Figure 3-38 Brake resistor installation on size 5
1. Remove the terminal covers as detailed in section 3.3.1 Removing
the terminal covers on page 22.
2. Remove the brake resistor bung from the hole in the chassis, the
closed end of the bung will need to be pierced so that the cable has
access to be routed through.
3. Feed brake resistor bung onto outer insulation of brake resistor
cable. The wider end of the bung should be inserted first. The
Narrow end should align with end of insulation.
4. Install the braking resistor to the heatsink using captive screws. The
screws should be tighten to a maximum torque of 2 N m (1.5 lb ft).
5. Route the cables through the provided hole at the rear of the
heatsink as shown in Figure 3-38 and take the cable out from the
front side of the drive. Ensure the cables are routed between the fins
of the heatsink, and the cables are not trapped between the heatsink
fins and the resistor.
6. Crimp the cable ends and make appropriate connections. The brake
terminals must be tightened to a maximum torque of 2 N m (1.5 Ib ft).
7. Replace the terminal covers on the drive, tighten to a maximum
torque of 1 N m (0.7 lb ft).
