Danger to life through electric shock due to incorrectly laid brake cables
If brake cables are laid without safe electrical separation, the insulation can fail and cause
an electric shock.
Install the brake in one of the following ways:
• Connect the holding brake with the specified MOTION-CONNECT cable.
• Only use third-party cables with safe electrically separated brake cores or lay the brake
Risk of fire as a result of overheated motor cables if permissible cross-sections are fallen
below
Excessively thin motor cables can result in overheating. This can result in severe injury or
death due to fire and smoke.
• Use cables that correspond to the Motor Module currents. Take into account the routing
• If smaller cross-sections are selected, you must ensure the appropriate level of
NOTICE
Temperature signal disturbances and failure of components as a result of unshielded or
incorrectly routed cables
With unshielded or incorrectly laid cables, it can be expected that interference will be
coupled into the signal processing electronics from the power side. This can result in
significant disturbances (fault messages) up to failure of individual components (destruction
of the devices).
• Only use shielded cables as temperature sensor cables.
• Only use temperature sensor cables that are routed together with the motor cable and
• Connect the cable shield to the chassis potential at both ends over a large surface area.
NOTICE
Premature wear of the motor holding brake when operated outside its permissible voltage
range
Operating the motor holding brake outside its permissible voltage range at the motor
connection will damage the brake.
• Ensure that the motor holding brake is only operated within its permissible voltage
