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.

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.
