3.6 Output Connections
3.6.1 Output Wiring
The output terminal block is located at the rear of the unit. Output connections are made to the
terminal block labeled OUTPUT. This terminal block has four posts: A, B, C and N (neutral or
common).

The output power cables must be large enough to prevent a total voltage drop exceeding 3 % of the
programmed output voltage between the power source and the load. Note that wires must be sized to

Always use the current available on the low voltage range to size the wires.
For cable lengths less than 25 feet, the following wire gauge is recommended:

3 Phase
1 Phase
Cable lengths must not exceed twenty-five (25) feet. For lengths greater than 25 feet, calculate the
voltage drop from the following formula:
2 X DISTANCE X CABLE RESISTANCE PER FT. X CURRENT = VOLT DROP
