Front view
Status: – Main switch open (OFF)
Material: – Complete Module C5G-UPS (refer to
Tab. 9.2 - Uninterruptible Power
Supply (UPS) on page 92)
Equipment: – Cross-headed screwdriver
Preliminary procedures / notes
Handle the module with care as it hosts a battery.
This module hosts a battery and shall be disposed of in compliance
with the environmental protection principles and laws in force. For
further details about the battery removal, refer to par. 10.5 Removing
the pile and battery from the Control Unit on page 99.
– Before replacing the UPS module due to an alleged fault, make sure it cannot be
ascribed to the battery protection fuse installed on the module.
Operating procedure
a. The UPS module is usually reachable and there is no need to remove other
components. If this is the case go to step c.
b. In case of optional modules mounted frontally that hinder the access, we
recommend acting as follows:
b.1 if possible, release the UPS module from the omega guide (releasing lever in the
upper part) passing behind the hindering components / plates and place the UPS
module on the electric cabinet inside base
b.2 or, remove the optional module on the far right to reach the UPS module from the
front. Normally it is not necessary to disconnect the option cables and it can be
moved on the side, allowing the operator to reach the module.
