WARNING

②

Twist the connection cable. When extending the connection cables, the cables

must be shielded additionally and connected on both sides.

Protective earthing is provided via the housing.

Wiring of an intrinsically safe braking resistor

Intrinsically safe braking resisitors behave in error case

such as a safety fuse. They interrupt themselves without

fire risk.

Use of non-intrinsically safe braking resistors

Fire or smoke in case of overload or fault !

► Only use braking resistors with temperature sensor.

► Evaluate temperature sensor.

► Trigger a fault on the drive controller (e.g. external input).

► Switching off input voltage (e.g. input contactor).

► Connection examples for non-intrinsically safe braking resistors
