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.

2. PWR-03D

2.1. 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.

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.
