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 failure". 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!
An interchanging of + (PLUS) and – (MINUS) avoids the correct function of the power feedback
unit.
Danger!
It is in no case allowed to pre-connect not current compensated direct inductances!
