Each power module has again two LED's to indicate the power state, the right LED Input power good [4] is
lightened if the connection to the power supply is OK. The left LED Output power good [2] is lightened, if the
output power of the module is OK. The table below lists the different LED status combinations and their meaning:

If you detected that one power module must be exchanged then, switch off the power supply by means of
the respective power switch [26] on the back of the
LED Input power good [4] should then be off.
•
On the front loosen the securing screw [1] of the defective power module. You need an Allen key size 3/16"
to turn the screw. This Allen key was provided with the system. When the screw is loosened use the handle
