• Remove the terminal covers.
• Remove the brake resistor bung from the hole (1) in the chassis, the closed end of the bung will
need to be pierced so that the cable has access to be routed through.
• 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.
• Install the braking resistor to the heatsink using the captive screws. The screws should be tighten
to a maximum torque of 2 N m (1.5 lb ft).
• Route the cables through the provided hole at the rear of the heatsink as shown in Figure 3-21
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.
• 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).
• Replace the terminal covers on the drive, tighten to a maximum torque of 1 N m (0.7 lb ft).
