IVS 102 Operating Instructions
Voltages up to 975 V DC (@ 600 V AC) may occur between the terminals.
Illustration 4.30: Brake connection terminal for B3.
Illustration 4.32: Brake connection terminal for C3.
NB!
If a short circuit in the brake IGBT occurs, prevent power dissipation in the brake resistor by using a mains switch or contactor to
disconnect the mains for the frequency converter. Only the frequency converter shall control the contactor.
NB!
Place the brake resistor in an environment free of fire risk and ensure that no external objects can fall into the brake resistor through
ventilation slots.
Do not cover ventilation slots and grids.
