How to Install
NOTE
Dynamic brake calls for extra equipment and safety considerations. For further information,
see the Instruction Brake Resistors for Horizontal A pp lications,MI50SXYY.
1. Use cable clamps to connect the shield to the metal cabinet of the adjustable frequency
drive and to the decoupling plate of the brake resistor.
2. Dimension the cross-section of the brake cable to match the brake current.
NOTE
Voltages up to 975 V DC (@ 6 00 V AC) may occur between the terminals.
NOTE
If a short circuit in the brake IGBT occurs, prevent power dissipation in the brake resistor
by using a line switch or contactor to disconnect the line power for the adjustable frequency
drive. Only the adjustable frequency drive should control the contactor.
