Injuries caused by parts falling over or off a forklift, pallet truck or transport vehicle. Only use means of transport that can carry the total weight and are suitable for it. 3.1 Notes on transport, installation and unpacking Improper transport of individual devices and minor machines, unsecured devices and minor machines stacked on top of each other or next to each other in packed or already unpacked condition is accident-prone and can cause damage or malfunctions for which we do not grant any liability or guarantee. Transport the scope of delivery secured against shifting or tilting with a sufficiently dimen- sioned industrial truck to the installation site. 3.1.1 General risks during internal transport CAUTION: DANGER OF TIPPING! The device may be lifted unsecured by a maximum of 2cm. Employees must be outside the danger zone, the reach of loads. Warn employees and, if necessary, advise employees of the hazard. Act responsibly during transport and always consider the consequences. Refrain from daring and risky actions. Gradients and descents (e.g. driveways, ramps and the like) are particularly dangerous. If such passages are unavoidable, special caution is required. Before starting the transport check the transport route for possible danger points, unevenness and disturbances as well as for sufficient strength and load capacity. Danger points, unevenness and disturbance points must be inspected before transport. The removal of danger spots, disturbances and unevenness at the time of transport by other employees leads to considerable dangers. Careful planning of internal transport is therefore essential.

15 Translation of original instructions DX17E EN DX17E_GB_3.fm 3.2 Unpacking the machine Transport the drilling machine in its packing crate near its final installation location with a lift truck before unpacking it. If the packaging shows signs of possible transport damage, take the necessary precautions not to damage the machine when unpacking it.

17 Translation of original instructions DX17E EN DX17E_GB_3.fm Please observe the following points:  The machine must only be installed and operated in a dry and well-ventilated place.  Avoid places near machines generating chips or dust.  The installation site must be free from vibrations also at a distance of presses, planing machines, etc.  The substructure must be suitable for the drilling machine. Ensure that the floor has suffi- cient load bearing capacity and is level.  The ground must be prepared in a way that potential coolants cannot penetrate the floor.  Any parts sticking out such as stops, handles, etc. have to be secured by measures taken by the customer if necessary in order to avoid endangering persons.  Provide sufficient space for the personnel preparing and operating the machine and trans- porting the material.  Also make sure the machine is accessible for setting and maintenance works. 3.6 Cleaning of the machine CAUTION! Do not use compressed air to clean the machine. Your new drill must be completely cleaned after it is unpacked to ensure that all moving parts and sliding surfaces are not damaged when the machine is operated. Each unit leaves the fac- tory with all exposed parts and sliding surfaces suitably greased to avoid oxidation during the time that elapses before it is placed into operation. Wipe all metallic surfaces with a clean cot- ton cloth. Clean the plastic parts with cleaning agents suitable for plastic. 3.7 First commissioning WARNING! First commissioning may only take place after proper installation. There is a danger to persons and equipment, if the first commissioning of the drilling machine is carried out by inexperienced personnel. We do not accept any liability for damages caused by incorrectly performed commissioning. 3.8 Warming up the machine ATTENTION! If the drilling machine and in particular the drilling spindle is immediately operated at maximum load when it is cold it may result in damages. INFORMATION To ensure a long service life of your drilling machine, we recommend that you do not exceed a maximum rotation speed of 500 rpm during the first hour of operation. If the machine is cold, e.g. directly after having transported the machine, it should be warmed up at a spindle speed of only 500 1/min for the first 30 minutes.

18 Translation of original instructions DX17E EN DX17E_GB_3.fm 3.9 Electrical connection The machine is installed and ready to operate. Please verify if the type of current, voltage and protection fuse correspond to the values specified. A protective earth ground wire connection must be available. Main Fuse 16A. Due to the design, the leakage current is greater than 3,5 mA. We ask for due attention while executing machine tests within the framework of industrial safety guidelines. The earth leakage current of the SINAMICS V20 inverter may exceed 3.5 mA AC. Due to this, a fixed earth connection is required and the minimum size of the protective earth conductor shall comply with the local safety regulations for high leakage current equipment. The SINAMICS V20 inverter has been designed to be protected by fuses; however, as the inverter can cause a DC current in the protective earthing conductor, if a Residual Current Device (RCD) is to be used upstream in the supply, observe the following:  The SINAMICS V20 single phase AC 230 V inverters (filtered or unfiltered) can be oper- ated on a type A1) 30 mA or type B(k) 30 mA RCD.  To use a type A RCD, the regulations in this FAQ must be followed: Siemens Web site (http://support.automation.siemens.com/WW/view/en/49232264) ATTENTION! Residual currents may already be present at your mains connection, or in the later course of time further residual currents from other devices may be added, which will then cause the residual current circuit breaker in conjunction with the SINAMICS V20 to trip. The 30mA residual current circuit breaker possibly used at your mains connection is then no longer sufficient or is already insufficient when the machine is installed. In this case it is only possible to use an RCD with 300mA at your mains connection. Whether then the RCD for personal protection with 30mA may be used against a 300mA RCD for fire protection alone, must be clarified by you with your network supplier, or your building insurance, or one of your electricians on site. Basically, 30mA RCDs are to be found on a normal household connection, which must not be replaced by 300mA RCDs. Industrial buildings usually have an RCD for fire protection with 300mA. INFORMATION The following pages contain general information on the operation of frequency inverters.

19 Translation of original operating manual GB Converter-plus-ELCB-plus-EMV_GB.fm 3.9.1 Regulated drives in connection with residual current devices Speed-controlled drives are one of the standard equipment in machine and plant construction and perform various tasks. Compared to a simple motor, the electronic rectifiers or converters require some special features for the necessary safety measures for electrical safety. Depend- ing on the application, the use of a fault current protection device, differential current monitor- ing or insulation monitoring can make more sense. For electrical safety, DIN VDE 0100-410 (VDE 0100 part 410): 1997-01 "Erection of heavy cur- rent installations up to 1000V" is a basic standard. It describes both, the admissible net forms and the necessary protective measures against dangerous body currents. Based on this stand- ard DIN EN 50178 (VDE 0160): 1998-04 "Equipping of heavy current systems with electronic equipment" specifies the protective measures to be applied to controlled drives in more detail. It calls for: "In the case of electronic equipment, the protection of persons against dangerous body currents must be carried out in such a way that a single fault does not cause any danger." Regulated drives with residual current devices The TN-S system is the most common network form for the operation of controlled drives. This is done, among other things, for EMV reasons and to avoid vagabonding currents. In accord- ance with DIN VDE 0100-410 (VDE 0100-410): 1997-01, fault current protective devices (ELCB) can be used as a protective measure against dangerous body currents. According to DIN VDE 0100-482 (VDE 0100 part 482): 2003-06 "Electrical installations of buildings", cables and wiring systems in fire-endangered plants must be protected by ELCBs with a rated differen- tial current of 300 mA. According to IEC 60755, ELCBs differ in the type of fault currents they can detect. In conjunction with electronic devices currents with DC components may occur. 3.9.2 Protection from Dangerous Shock Currents, use of ELCBs To achieve increased safety in all installation systems, and in power supply ranges for which the installation provisions stipulate or recommend the ELCB devices. Measure for “Protection from Dangerous Shock Currents”, as regulated in DIN VDE 0100 Part 410. All measures are to be mentioned:  Protection from indirect contact – as protection against fault by shutting down in the event of inadmissibly high contact voltage by short circuit shock on the operating resource.  Protection from direct contact – as additional protection by shutting down in the event of contact with a live conductor. Dangerous shock currents are shut down within the shortest possible time, if the rated fault current of the circuit breaker is 30 mA (e.g. Domestic environment), for a personal protection system 10 mA (e.g Bathroom).  Fire prevention – Prevention of the origination of electrically-ignited fires if the rated fault current of the circuit breaker is 300 mA. Operating premises at risk of fire to VdS 2033: 2002-02 300 mA (e.g. Factory halls). 3.9.3 Current in the protective earth conductor - Leakage current With EMC filters in frequency converters, the leakage current is always greater than 3.5 mA due to physics. Some types of frequency converters also achieve a leakage current of up to 300mA. Therefore, a fixed earth connection is required and the minimum cross section of the protective earthing conductor must conform to local safety regulations for devices with high leakage cur- rent. This is achieved by providing a permanent fixed earthing connection with two independ- ent conductors, each having a cross section the same as the power supply cord or greater. Preferably, machines with frequency converters are therefore to be permanently connected to a terminal box, otherwise an additional fixed earth connection is required, which is not routed over the plug, and must correspond to at least the cross-section of the cable in the plug. Since a direct current may be caused by the frequency converter in the protective earthing con- ductor, if an upstream residual current device (ELCB / RCD) is required in the network, the fol- lowing guidelines must be followed:

20 Translation of original operating manual GB Converter-plus-ELCB-plus-EMV_GB.fm To avoid an operating fault, you need an AC/DC-sensitive ELCB. Be absolutely sure which leakage current security is necessary for dangerous body currents, as regulated in DIN VDE 0100 part 410, at your mains connection. 3.9.4 When the ELCB triggers  Pulse current - sensitive ELCB type A ELCB type A independent of rated voltage, for triggering when changing fault currents and pulsing DC fault currents.  AC/DC - sensitive ELCB type B ELCBs of series type B also accept the detection of smooth AC fault currents as well as the detection of fault current shapes of type A; they are therefore suitable for all the circuits mentioned. ELCBs of this series therefore detect all types of fault current according to the triggering characteristic B, i.e. both smooth DC fault currents and also all AC fault currents of all frequencies and mixed frequencies up to 1 MHz are detected and switched off reliably in the event of a fault.  Alternating current - sensitive ELCBs of type AC (only alternating current) are unsuitable for frequency converters. Alternating current - sensitive ELCBs of type AC are not customarily used and are no longer permitted in Germany. Type B must be used with 3-phase converters. When using an external EMC filter, to avoid false error shutdowns, a time delay of at least 50 ms is required. The leakage current can exceed the threshold trigger value for an error shut- down if the phases are not switched on at the same time.
