•
Connect the power supply cable to the terminal on the backside of the unit.

When connecting the power supply cable, tighten the terminal screws to the following torque.
•
The power source must be within the allowable voltage fluctuation.
•
Use a power source with low noise between the cables or between the ground and the cable.
•
Use as thick a power supply cable as possible to minimize drop in voltage.
•
Keep the power supply cable a sufficient distance from high-voltage, large-current carrying cables.
•
Be sure to attach the terminal cover to the terminal block.
Grounding
•
An independent earth pole must be used for POD.
•
Use a cable which has a nominal cross section of more than
2 mm

for grounding.
•
Set the grounding point near the POD to shorten the distance
of grounding cables.
