Replacing overvoltage protection

AC overvoltage protection
↻ NOTE: If the message "Overvoltage protection module defective" ap-
pears in the web interface, these modules must be replaced.
↻ NOTE: Ensure that the device is completely free of AC/DC voltage.
1. [ [See section 7.2} Page 24]].
2. Remove faulty modules individually from the plug-in frame and replace with a
module of the same type.
NOTE: Different AC surge protection modules are used. The designation
on the PCB must match the module code (GTD/MOV).
1. Insert the AC overvoltage protection modules into the plug-in frame one after
another.
2. Ensure that all protective elements are properly secured.
ð Proceed with the installation of the device.
DC overvoltage protection
↻ NOTE: If "defective" appears in the status display of the overvoltage
protection module, it must be replaced.
↻ NOTE: Absence of AC/DC voltage ensured.
1. [See section 7.2} Page 24].
2. Unlock faulty modules via the locking latch.
3. Remove the defective modules one-by-one out of the DC base and replace with
a module of the same type.
. NOTE: The coding at the base plug-in position must match the cod-
ing on the module.
4. Insert the DC overvoltage protection modules into the DC base one after an-
