50 5163667/06 EN ETOS® IM 5.2.4 Information about shielding the CAN bus In order for the CAN bus to operate faultlessly, you have to connect the shielding using one of the following variants. If you are not able to use any of the variants detailed below, we recommend using fiber-optic cables. Fiber- optic cables decouple the devices and are not sensitive to electromagnetic interference (surge and burst). NOTICE Damage to the device! If you connect the CAN bus cable to devices with different potentials, cur- rent may flow across the shielding. This current may damage the device. ►Connect the devices to a potential equalization rail to equalize the poten- tial. ►If both devices have different potentials, only connect the CAN bus cable shielding to one device. Variant 1: The connected devices share the same potential If the devices to be connected share the same potential, proceed as follows: 1. Connect all devices to a potential equalization rail to equalize the poten- tial. 2. Connect the CAN bus cable shielding to all connected devices. Variant 2: The connected devices have different potentials Note that the shielding is less effective with this variant. If the devices to be connected have different potentials, proceed as follows: ►Connect the CAN bus cable shielding to just one device. Connecting shielding Connect the shielding for the CAN bus cable to the 9-pin D-sub connector: Figure 29: Connection of CAN bus cable shielding to the 9-pin D-sub connector

WARNING Electric shock! Connection errors can lead to death, injury or property damage. ►Ground the device with a protective conductor using the grounding screw on the housing. ►Note the phase difference of the secondary terminals for the current transformer and voltage transformer. ►Connect the output relays correctly to the motor-drive unit. Supply the voltage via separators and ensure that current paths can be short circuited. Fit the separator, clearly labeled, close to the device's power supply so that it is freely accessible. This ensures that the device can be re- placed with ease in the event of a defect. Wiring information Note this procedure for the wiring: ▪To obtain a better overview when connecting cables, only use as many leads as necessary. ▪Note the connection diagram. ▪Only use the specified cables for wiring. Note the cable recommendation.

58 5163667/06 EN ETOS® IM 5.6.1 Cable recommendation Please note the following Maschinenfabrik Reinhausen recommendation when wiring the device. Excessive line capacitance can prevent the relay contacts from breaking the contact current. In control circuits operated with alternating current, take into account the effect of the line capacitance of long control cables on the func- tion of the relay contacts. If you want to route Ethernet connections from a control cabinet or building, we recommend the use of fiber-optic cables (in accordance with the IEC 61850-90-4 recommendation).

61 5163667/06 EN ETOS® IM Figure 43: Example of a soldered shielding on a plug housing 5.6.3 Notes on connecting to the MR sensor bus The optionally available MR sensor bus function lets you connect digital and analog sensors to the device over Modbus RTU. The MR sensor bus sup- ports the connection of up to 31 sensors (Modbus slaves). The ISM® device operates as the Modbus master. Ensure that no other Modbus master is connected over the MR sensor bus. Assign a unique Modbus address to each sensor you are connecting over MR sensor bus. The MR sensor bus may experience errors if multiple sen- sors are using the same Modbus address. Observe the following notes for connecting the sensors: ▪ NOTICE! Damage to the device or sensor. Connect all of the sensors to the potential equalization rail to avoid circulating currents over the MR sensor bus. ▪The MR sensor bus uses Modbus in a 2-wire configuration (2W). The 4- wire configuration (4W) is not supported. ▪They have to connect the sensors over a shielded line with 3 conductors (D0, D1, Common). The data lines (D0, D1) have to be in twisted pairs. Note the cable recommendation. ▪Stubs of bus nodes for each node must be shorter than 20 m. ▪The CPU assembly contains a terminating resistor (120 Ω) at the COM2 interface. Install another terminating resistor (120 Ω, 0.5 W) at the other end of the bus. ▪The CPU assembly contains a pull-up resistor and a pull-down resistor (each of 680 Ω in accordance with the Modbus specification). No addi- tional pull-up/pull-down resistors are needed.
