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!
► Unplug all connections to the module. You may want to mark their positions, to make clear as-
signment easier later on.
Fig.59:
► To release the module, press the lever
(1) at the back of the module down and
then pull the module off the rail.
Installation
► Follow the removal instructions in reverse order for installation. Also observe the following
instructions:
– Set the voltage (see 3.4.8.1 "Setting the Voltage on the AC/DC Converters" [}61]).

3.4.8.1 Setting the Voltage on the AC/DC Converters
Parts, equipment and tools
●
Voltage measuring device
Overview
Fig.60: AC/DC converter
The AC/DC converters are located in the
rack unit between location 3 and 4.
A5) AC/DC converter (24 VDC, set to 25
VDC)
for Power Fail, safety circuit SSK, tape cut-
ter, PCB handling
The power fail signal is generated by the
AC/DC converter A5 and sent to the GCU
and HCU. (X200:9, X200:10)
A6) AC/DC converter (27 VDC)
for FCU (gantry 1 and 4)
A7) AC/DC converter (27 VDC)
for FCU (gantry 2 and 3)
A8) AC/DC converter (36 VDC, set to 42
VDC)
for HCU (gantry 1 to 4)
CAUTION
Check the values
► Check the set values and correct if necessary.
To A5:
There is 24V present at the following fuses:
F10 Conveyor electrics F11 Y motor fan, safety circuit (internal)
F12 Distributor power (line 1) F13 Distributor power (line 2)
F14 Power fail F20 Cover fan gantry 1 and 4
F21 Cover fan gantry 2 and 3
Setting
Fig.61: Setting the voltage
► Open the protective cap on the setting
screw(1).
► Use a flat-bladed screwdriver to set the
correct voltage on the AC/DC con-
verter.
Check the voltage with a suitable
voltage measuring device between the
terminals + and–.

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 screws fastening the cover and swing the cover towards the front. The AC/DC
converters are also fitted on the cover. These are swung away with the cover.
► Unplug all connections to the rectifiers. You may want to mark their positions, to make clear
assignment easier later on.
► Remove the screws fastening the rectifier and remove the rectifier.
Installation
► Follow the removal instructions in reverse order for installation. Also observe the following
instructions:
– Apply a heat-conductive paste between the metal frame and the rectifier.
