Danger!
Danger of personal injury! Destruction of the controller!
Damaged control cables in the controller (master and slave) may
cause a faulty control of the output stage.
Possible consequences:
ƒ When switching on the mains voltage, high energies may
discharge like an explosion.
ƒ Explosive noises may damage your hearing. A shock by an
unexpected and loud explosion may cause distress.
ƒ The controller will be destroyed.
Protective measures:
ƒ When working with the DC busbars, make sure that you do
not damage any internal connectors and cables.
ƒ Before attaching the cover again:
– Check all plugs selected in Fig. 5.5−5 for damage and correct
fit.
– Check all cables involved for damages.
– If the plugs do not fit correctly, or the plugs or cables are
damaged, commissioning is prohibited. Contact the Lenze
service.
