Vertical with power connection at the top
100 mm above and below
The requirements to IEC 61800-3 are complied with when the regenerative
power supply module is installed according to the demands of the CE-typical
drive system
The limit class A to EN 55011 is complied with when the regenerative power
supply module is installed according to the demands of the CE-typical drive
system
Compliance with the limit values to IEC 61800-3
Overvoltage category III to EN 50178
> 3.5 mA; i.e. fixed installation is required; the PE connection must be carried
out to EN 50178
No restrictions
Not permitted
Not permitted
Please observe the permissible mains voltage and current limits (
higher voltage or current destroy the regenerative power supply module.
Regenerative power supply modules must not be connected in parallel in
the DC bus.
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.
Please observe the circuit proposals (
Please observe national and local regulations!
