Braking resistors may be subject to unexpected overloads due to faults.
Resistors MUST be protected using thermal cutouts. These devices must not interrupt the circuit in which the resistor is
inserted but their auxiliary contact must cut off the power supply to the power section of the drive. If the resistor requires a
protection contact, this must be used together with that of the thermal cutout.
A la suite de pannes, les résistances de freinage peuvent être sujettes à des surcharges imprévues. La protection des résist-
ances au moyen de dispositifs de protection thermique est absolument capitale. Ces dispositifs ne doivent pas interrompre le
circuit qui abrite la résistance, mais leur contact auxiliaire doit couper l’alimentation du côté puissance du drive. Si la résist-
ance prévoit un contact de protection, ce dernier doit être utilisé conjointement à celui du dispositif de protection thermique.
Note! Refer to the Gefran LIFT catalogue (cod. 1S9CLM) for resistor weights and dimensions.
