Mains connection
Connection to earthed three-phase power supply system (TN-C mains supply).
Asymmetrically earthed supply systems must be connected via an isolating
transformer!
Connection to the T-NC mains
DS400-Netzanschluss-T-NC
The max. supply voltage of 528 V~ must not
be exceeded at any time (not even for short
intervals)!
Danger of damage!
F1 = device protection
safety fuses FF, F, or semi-conductor
automatic fuses
Install an additional power line filter for high
EMC requirements.
Bus filter and input capacitors are installed.
Leakage current > 60 mA
Connection to the T-NC mains using an auto-transformer
DS400-Netzanschluss-T-NC-Trafo
The max. secondary voltage of the
transformer of 528 V~ must not be exceeded
at any time (not even for short intervals)!
Danger of damage!!
Slow-acting transformer fuses
F1 = device protection:
safety fuses FF, F, or semi-conductor
automatic fuses
Install an additional over-voltage protective
device for protecting against switching surges
of the transformer.
Install an additional power line filter for high
EMC requirements.
Bus filter and input capacitors are installed.
Leakage current > 60 mA.
If the supply voltage is < 30 V the output stage is electronically de-activated.
