Braking Resistor (10% Duty Cycle) Installation
Since the Braking Resistor Unit generates heat during the dynamic
braking operation, install it in a location away from other equipment
which emits heat.
1. Mount the Braking Resistor Unit on a vertical surface, maintaining minimum 1.18 inch (30
mm) clearance on each side and 5.91 inch (150 mm) clearance top and bottom.
2. Open the Braking Resistor Unit terminal box to access its terminal block. Connect the
Braking Resistor Unit to the drive and external control circuit according to the following table
and Figure A6-2.
