Connection
•
All connections should be as short and low-impedance as possible.
•
For the observance of the EMC-guideline (in accordance to actual standards like
VDE 0160 and EN 50178) screened wires have to be used.
•
Connect the mains supply wires at the terminals L1, L2, L3 (at the mains choke)
of the power feedback unit. Only three phase connection is allowed.
•
A defined phase sequence (clockwise rotation field) must be observed at the
main circuit connection of the power unit. The power feedback unit is equipped
with a phase-sequence control unit. In case of an incorrect rotation field an error
message is displayed via LED as follows: "rotation field failure" or "phase fail-
ure". In this case two phases, connected to the power unit, have to be exchanged.
•
Connect the earthing wire of the supply cables to the earthing screw of the
power feedback unit.
•
The wires for the DC-bus coupling between controller and power feedback unit
have to be connected to the DC-terminals. It is absolutely necessary to observe
the correct polarity.
Danger!
Interchanging of + (PLUS) and – (MINUS) avoids the correct function of the power feedback
unit.
Danger!
It is in no case allowed to pre-connect uncompensated direct inductances!
