The brake rotor can stick to the housingt after a longer storage time. Then the motor cannot turn
even when the brake is bled. In this case, bleed or remove the brake and release the brake rotor
carefully from the housing.
Danger!
The levers for hand release must be removed after brake hand release action.

Triggering of the brakes
It is recommended to switch the brake through two contactors, one is switching the AC-side (K4) and
the other is switching the DC-side (K3).
To reduce noises during brake disconnect the brakes should be switched to the alternating current
side (K4), while normal operation. The brakes are switched-off slower and thus quieter through the
recti
fi
er.
To ensure instantaneous brake application in emergencies, during inspection drives and return rides,
use a second contactor (K3), which disconnects the brakes from the direct current side. Integrate this
contactor into the safety circuit.
CAUTION!
Caution!
Brakes, which are connected to the direct current side, must be protected against excess voltage from
the switching actions by using corresponding varistors!
Due to the high operating current, master contactors must be used to switch the brakes!
