4.3.4 Establishing mains connection
Only applicable for configurations with integrated power supply pack (DCU 110, DCU 180, DCU 310
and DCU 400). The DCU 002 receives the supply voltage via the electronic drive unit RS-485 interface.
Establishing mains connection for DCU
1.
Make sure that the “S1” power supply pack master switch is off prior to connection.
2.
Always ensure a secure connection to the earthed conductor (PE), protection class I.
3.
Insert the mains connector cable (not included in the shipment) in the "AC in" mains connection
plug at the rear side of the device.
4.
Secure the connection with the mounting bracket.
5.
Connect the mains cable to the mains power supply on the customer-side.
