Stop!

Possible overheating of the brake resistor during
operation

Inadequate heat dissipation during operation can
cause the brake resistor to overheat.

Possible consequences:

ƒ

The brake resistor is destroyed.

ƒ

The drive is not braked but coasts to a standstill.

Protective measures:

ƒ

Always connect the thermal contact of the brake
resistor.

ƒ

Integrate the thermal contact into the overall
equipment monitoring apparatus in such a way
that the supply of power to the standard device is
switched off if the brake resistor overheats (e.g.
switch−off by means of mains contactor control).
