 Stop!

Please strictly observe the following operating conditions, otherwise the

regenerative power supply module may be destroyed.

ƒ Please observe the permissible mains voltage and current limits ( 86). A

higher voltage or current destroy the regenerative power supply module.

ƒ Regenerative power supply modules must not be connected in parallel in

the DC bus.

ƒ The use of an additional brake chopper is only permitted if the brake

chopper only limits the DC bus voltage if a power failure or a failure of the

regenerative power supply module occurs; i. e.

– the regenerative power supply module must be designed in a way that the

entire braking energy can be dissipated in every operating state.

– the feedback operation and the brake chopper must not be operated at

the same time.
