This is how you remove a Motor Module

Overview
The activities required when replacing a Motor Module are subsequently described.
If a Motor Module has a hardware defect, then it must be replaced by an identical module.
Preconditions:
● The module is defective and must be replaced.
● The control cabinet is in a no-voltage condition, all of the connectors and cables are labeled.
Removing
Procedure:
1. Switch-off the control: Completely switch off the system. Check that the system is in a no-
voltage condition and is locked-out so that it cannot be switched on again without the
appropriate authorization.
2. Access the control cabinet where the infeed module is located.
3. If it has not already been done, label all connectors and cables that lead to the module now.
Only then, can it be ensured that the cables are not interchanged.
4. Withdraw the enable terminals X21 (and X22 if available).
5. Withdraw the connected DRIVE-CLiQ cables X200 - X202.
6. Release the fixing screw (Torx) and remove the motor connection X1 (and X2 - if available).
Danger to life through electric shock due to the residual charge of the DC link capacitors
As a result of the DC link capacitors, a hazardous voltage is present for up to 5 minutes after
the power supply has been switched off.
Contact with live parts results in death or serious injury.
● Do not open the protective cover of the device until 5 minutes have elapsed.
● Before starting any work, check that the system is in a completely no-voltage condition by
● Ensure that the associated warning plate in the appropriate language is attached.
1. Open the protective cover of the DC link voltage of the defective module as well as the
adjacent module - if available - using a suitable tool (e.g. a screwdriver).
2. Withdraw the 24 V terminal adapter.
