How to Install
NOTE
Voltages up to 975 V DC (@ 600 V AC) may occur between the terminals.
NOTE
If a short circuit in the brake resistor occurs, prevent powe r dissipation in the brake resistor
by using a mains switch or contactor to disconnect the ma ins for the adjustable frequency
drive. Only the adjustable frequency drive can control the contactor.
