3.7.1. DCS880/DCT880 control panel

The control panel of the DCS880/DCT880 unit enables the user to control, read the status
messages and set the parameters of the DCS880/DCT880 unit. The panel can also be used to
copy parameters from one DCS880/DCT880 unit to another DCS880/DCT880.
For more information, see Section 8.5, "EXU control panel", page 124.

3.7.2. Output disconnector

The optional output disconnector is used to disconnect the EXU from the motor for
maintenance purposes.

3.8. Door interlocking system

Each PCU has an electromechanical interlocking system to keep the PCU doors locked and
secure during operation to prevent contact with hazardous voltages. The main protection
features of the interlocking system are locking bars (1) and grounding switches (2).

You can only connect the main power supply to the drive when all of the locking bars are in the
locked position and the grounding switches in the ungrounded position. Similarly, you can only
open the PCU doors after the main power supply has been disconnected, the DC-link capacitors
have been discharged, and the grounding switches are in grounded position.
The doors of the COU (control unit and motor terminal section) and the WCU are not integrated
into the interlocking system and can be opened any time.
CAUTION! DO NOT open the swing frame of the control unit while the drive is in operation.
For instructions on how to open and close doors, see Section 10.6.3, "Opening and closing the
doors", page 171.
