Mains Voltage and Connection
The Power supplies are equipped with a “World”- mains input (rated voltage range: 100-240
VAC, frequency: 50-60 Hz, rated current: 16 A). Before connecting to the mains please
double-check correspondence.
Mains input connection at the power supply side is done with a 3-pin HIRSCHMANN
connector or power terminals. There is no main fuse inside. A circuit breaker for overcurrent
protection 16A, type B or C (EN / IEC 60898, VDE 0641), has to be installed externally.
Before disconnection the HIRSCHMANN connector, the power supply should be switched
into standby state. (Use the ON/OFF-Switch of the front pannel of the MPOD system)

Safety
After connecting the Power box to the mains, the mains input module is powered permanently.
Filter and storage capacitors of the power factor correction module are charged with about
400VDC
. Any DC-On-Signal as well as a power switch at control board (if any installed) operates
as a low voltage DC on/off switch only and not as a mains breaker.
Therefore it becomes
dangerous if the box cover is open. In this case a lot of components on high voltage potential
get touchable!
Before starting any kind of work inside the power box remove the unit from mains and wait
a couple of minutes with your activities! Discharge the primary DC Filter-capacitors by use
of a well isolated 22 ohm 10W resistor.
We recommend in case of any malfunction to send the power box to Wiener or to one of our
representative for service
The backplane is connected to 385 V DC voltage. So never touch the backplane or its
connectors!
