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.
ƒ Please observe the circuit proposals (
¶ 124) .
ƒ Please observe national and local regulations!
