11.4 Inspection of the DC link capacitors of the PM modules
Power module
PE
Power module to be formed
Forming circuit comprising power modules with PTC resistors
Before forming the DC link capacitors, it is imperative that the DC link bridge
is removed.
Ensure that the power module does not receive a switch–on command.
Connect the forming circuit.
Over the course of the forming time, the incandescent lamps must become
darker/go out completely. If the incandescent lamps are continually lit, then
there is a fault in the power module the wiring.
When forming using PTC resistors, the modules must remain in the circuit
for approximately 1 hour. If there is a fault in the power module, then the
resistors will become very hot (surface temperature > 80 °C).
