Risk of electric shock if dismounting steps are continued before the electric device is
discharged and a safe voltage level has been measured.
Do not touch the electric device or continue to work with the electric device until it cools
down.
Do not use excessive force when you disconnect the connector, because the plastic housing of
the connector can break. Release the retaining clip of the connector before you disconnect
the connector.
Do not try to unplug the X1 or X2 connectors by pulling from their wires.
Support the electric device during dismounting, handle it with care.
When the device is dismounted and stored and packed for delivery, measure that there is no
voltage and then install short circuit wire to the conductor rails to prevent charge from
building up.
Refer to Chapter
on page 34 for additional information.
Dismounting procedure
1. Switch off the electric device.
2. Make sure that the cooling system remains operational.
3. Release the retaining clip of the X1-connector (control signal connector, low voltage, 35-pin) and
disconnect the connector.
4. Wait until the electric device has fully discharged. Always measure that no voltage is present on the
power terminals before you proceed.
5. Wait until the temperature of the electric device and cooling liquid has decreased below +40°C.
6. Remove the mounting screws and dismount the electric device from the mounting base.
7. Dismount the connector shield (mechanical safety component).
8. Dismount the connection box lid (power terminal cover).
9. Disconnect the power terminal cabling and the grounding cables (protective earth).
10. Disconnect the liquid cooling system.
11. Install the connection box lid and other parts and plug all electrical and cooling connections for
longer storage.
12. Lift off the electric device according to Chapter
on page 27.
