Note: All wire sizes based on 75°C copper wire, 40°C ambient temperature, 4-6
conductors per conduit or raceway.
Power Connections The signals are shown in Figure 3-5 and described in
Table 3-3.
1. Remove the cover, shown in Figure 3-2.
2. Loosen the grounded cable clamp, Figure 3-5.
3. Connect the Mains Cable, Motor Cable, Dynamic Brake Cable and
Thermistor Cable wires, if used to their proper clamp terminal, Figure
3-5. Be sure the shields of all shielded cables are in contact with the
grounded cable clamp.
Note: This control must have two separate mains earth grounds connected as
shown in Figures 3-5 and 3-6.
4. Tighten the grounded cable clamp screws to securely hold the cables.
