Maintenance
Module Removal and Replacement
The modules in the frame can be removed for maintenance. Unscrew the
two front panel catches and lower the front panel. Note that the Local
Control Panel, if fitted, is attached to the plug-in modules by a pair of
ribbon cables. Switch off the unit with the standby/on switch (left off or
standby) at the front of the power module. Open the latches of the ribbon
cable connectors and disconnect the panel.
A blank front panel, usually with a power on indicator board, is fitted to
most units not having a control panel. It is attached to the power supply
module by a flying lead which can be detached from the power supply
module by pulling upwards. Do not allow the blank front panel to hang by
the lead as this may apply excess stress to the lead and cause premature
failure.
The plug-in modules can be removed using the handles. These handles act
as levers to aid removal and insertion of the modules plus they incorporate
a locking mechanism to prevent the modules coming loose, especially
useful in a mobile application. Pull the handles to initially release the lock
and then to withdraw the module.
When replacing the module it is essential to ensure that the handles are
wide open as you push the module into the guides until the resistance of
the edge connectors is felt. Then push evenly on the handles to push the
module securely in place.
