6.2.2. Replacement of Power Supply Plug-in Modules
The power supplies can be set up redundantly. Therefore, the system stays in
operation during replacement of one PSU. When replacing a broken PSU by a new
one, proceed in the following order:
- Disconnect mains from the defect PSU by unplugging the IEC power
connector.
- Pull out the defect PSU plug-in module carefully at the locking device from the
front side. Use your finger for pressing down the spring inside the locking
device.

- Note: To get access to the PSU, the sheet by which the PSU is covered must
be removed. Therefore, unscrew the four M3x6 Phillips countersunk-head
screws.
