___________________________________________________________________________ ___________________________________________________________________________ version 1.0 page 2 1. Safety Regulations VERY IMPORTANT: Instruments and components supplied by npi electronic are NOT intended for clinical use or medical purposes (e.g. for diagnosis or treatment of humans), or for any other life-supporting system. npi electronic disclaims any warranties for such purpose. Equipment supplied by npi electronic must be operated only by selected, trained and adequately instructed personnel. For details please consult the GENERAL TERMS OF DELIVERY AND CONDITIONS OF BUSINESS of npi electronic, D-71732 Tamm, Germany. 1) GENERAL: This system is designed for use in scientific laboratories and must be operated by trained staff only. General safety regulations for operating electrical devices should be followed. 2) AC MAINS CONNECTION: While working with the npi systems, always adhere to the appropriate safety measures for handling electronic devices. Before using any device please read manuals and instructions carefully. The device is to be operated only at 115/230 Volt 60/50 Hz AC. Please check for appropriate line voltage before connecting any system to mains. Always use a three-wire line cord and a mains power-plug with a protection contact connected to ground (protective earth). Before opening the cabinet, unplug the instrument. Unplug the instrument when replacing the fuse or changing line voltage. Replace fuse only with an appropriate specified type. 3) STATIC ELECTRICITY: Electronic equipment is sensitive to static discharges. Some devices such as sensor inputs are equipped with very sensitive FET amplifiers, which can be damaged by electrostatic charge and must therefore be handled with care. Electrostatic discharge can be avoided by touching a grounded metal surface when changing or adjusting sensors. Always turn power off when adding or removing modules, connecting or disconnecting sensors, headstages or other components from the instrument or 19” cabinet. 4) TEMPERATURE DRIFT / WARM-UP TIME: All analog electronic systems are sensitive to temperature changes. Therefore, all electronic instruments containing analog circuits should be used only in a warmed-up condition (i.e. after internal temperature has reached steady-state values). In most cases a warm-up period of 20-30 minutes is sufficient. 5) HANDLING: Please protect the device from moisture, heat, radiation and corrosive chemicals.

PWR-03D The external power supply PWR-03D is capable of driving up to 3 EPMS-E housings or an EXT-16DX amplifier with R/I-T1DX. Each housing is connected by a 6-pole cable from one of three connectors on the front panel of the PWR-03D to the rear panel of the respective EPMS-E or EXT-16DX / R/I-T1DX housing (see Figure 1, Figure 3). A POWER LED indicates that the PWR-03D is powered on (see Figure 1). Power switch, voltage selector and fuse are located at the rear panel (see Figure 2). Note: The chassis of the PWR-03D is connected to protective earth, and it provides protective earth to the EPMS-E housing if connected. Figure 1: PWR-03D front panel view Figure 2: PWR-03D rear panel view Note: This power supply is intended to be used with npi EPMS-E or EXT-16DX / R/I-T1DX systems only. 2.2. System Grounding EPMS-E-07 (EXT-16DX) The 19" cabinet is connected to the CHASSIS connector at the rear panel. It can be connected to the SYSTEM GROUND (GND) on the rear panel of the instrument (see Figure 3). Without this connection, the EPMS chassis and the chassis of all modules plugged in is free floating. Note: The EPMS-E-07 / EXT-16DX chassis is not connected to protective earth. Important: Always adhere to the appropriate safety measures. Figure 3: Rear panel connectors of the EPMS-E-07 (left) and EXT-16DX (right). 2.3. Technical Data PWR-03D Input: 115/230 V AC, 60/50 Hz, fuse 1.6/0.8 A, slow Dimensions: (W x D x H) 225 mm x 210 mm x 85 mm
