prevented from penetrating the inside of the housing.
If available: Remove cover from slot X107, plug programming module of
defective component in slot X107 of new component, check sealing ring
of cover for damage (if sealing ring damaged: provide new sealing ring),
mount cover (screw tightening torque: 1 Nm)

11.4.5 "Release holding brake" service function
Lethal injury caused by errors when
controlling motors and working at moving
parts!
● Do not work at running or unsecured installations.
● Before starting to dismount, secure the machine against accidental
movements and unauthorized operation.
● Before dismounting them, secure the motor and the supply lines unit
against falling or movements, before unfastening the mechanical
connections.
Via the X141 interface, it is possible to "release" the integrated holding brake:
● A voltage of 30 … 46 V has to be applied at X103.1 (pins 11 and 12).
● Short-circuit pin 3 with pin 9 at X141.
