2.5.2 Split-Phase Supply Connections 120–0–120V
1. Remove the protective cover from the terminal block.
2. Route the cables through the strain relief device. Refer to Table 3–2 for cable
recommendations.
3. Connect NEUT to 120V.
4. Connect LINE to the other 120V.
Wiring across the full voltage will allow lower line currents to be used.
5. Reinstall the protective cover on the terminal block. Tighten the strain relief device.
2.5.3 Three–Phase Supply Connections
1. Remove the protective cover from the terminal block.
2. Route the cables through the strain relief device. Refer to Table 3–2 for cable
recommendations.

WARNING!
To protect the operator, the wire connected to the GND
terminal must be connected to earth ground. This unit should not be operated
without an adequate ground connection.
CAUTION!
A device to disconnect the CW system from the energy supply
source is required. This switch or circuit breaker must be close to the CW
system, within easy reach of the operator, and clearly labeled as the
disconnection device for the CW system.
CAUTION! Use wire rated for currents drawn as specified
on equipment label.
