Usage of an earth leakage circuit breaker
If you want to use an earth leakage circuit breaker, please take note of
the varying requirements for protection against fire and the protection of
individuals.
Regatron recommends the usage of an earth leakage circuit breaker
sensitive to AC and DC leakage currents.
6.2.3.3. DC connection/load connection
The output connections are laid to the rear side of the device as current
bars.
For the load connection you must pay attention to the following aspects:
Use a cable cross-section to suit the device power and nominal
voltage. (See Table 42, unterhalb.)
Screw cable to current bars using cable lugs
Hole diameter: 9 mm
Follow the standards applicable to the related application and type of
cable laying. The values in the table are only a recommendation.
Nominal voltage
on DC side
Cross-section [mm 2 ] – cable on DC side
20 kW device 32 kW device
50 V 95 150
100 V 70 70
200 V 35 50
500 V 16 25
1000 V 6 10
1200 V 6 10
Table 42 Cross-section sizing for the load cable as a function of the output voltage.
For cable lengths of more than 5 m the next size cross-section up
should be selected to keep the voltage drop over the load cable in
limits.
