3.4.4 Checking the Input Voltage at the Inrush Current Limitation Board
DANGER
Observe the safety instructions
There is a risk of dangerous touch voltages and short circuits occurring in inrush current
limiter boards which have been made accessible and are connected for measurement pur-
poses or bridging checks.
Nonobservance of these safety instructions may cause injury to personnel and dam-
age to the machine!
Measurements may only be performed by specially trained service technicians, with appro-
priate qualifications and expertise.
► Observe in particular the sections 1.1.3 "Safety instructions for the power supply
(without SMPS)" [}12] and 1.1.4 "Safety instructions for the power supply (with
SMPS)" [}13].

X1, X2, X3: connectors for configuring the
inrush current limitation on the board(2)
The inrush current limiter board must be set
to 400 V, irrespective of the supply voltage.
Use plug-in jumpers for this. Observe the
label on the protective grid.
Checking/setting
► Remove the mesh cover on the boards. To do this, remove the four screws on the side of the
cover.
► Check the jumper arrangement and correct if necessary.
Take note of the position of jumper J1 (see 3.4.7 "Inrush current limiter servo (A1)" [}59]).
► Fit the protective grid into place.

Removal
► Switch off the machine, disconnect it from the power supply and secure it to prevent
unauthorized reactivation.
1.2 "Preparatory work..." [}16]
► Before you start working, check the power supply for absence of voltage and observe the
waiting times!
► Remove the mesh cover on the boards. To do this, remove the four screws on the side of the
cover.
► Unplug all electrical connections to the inrush current limiter transformer. Mark their positions,
to make clear assignment easier later on.
► Remove the screws fastening the inrush current limiter for the transformer and then remove
this.
Installation
► Follow the removal instructions in reverse order for installation. Also observe the following
instructions:
– Make sure that the input voltage has been set correctly at the inrush current limiter trans-
former (see label on the mesh cover).
