Not all events can be displayed and please consult the operational manual for operational related problems.
On all relay contacts and power inlet voltage terminal suppressors are placed to limit the surge voltage and current
as well absorbing energy. The surge protecting devices protect the rack input voltage and relay contacts against
surges generated by electromagnetic effects such as lightning or electrostatic discharge, over-voltages and high
inductive loads. If a device is overloaded it can explode during the protection process. Consult OPW if this has
happened.
Do NOT replace fuses if the reason of a blown fuse is unknown.
Caution: When replacing the fuses, always make sure that you replace the fuse with original
ones with an equal stated value.
