2. Power Supply Cable Connection
Power Supply Cable Connection
• 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
2mm
2
for grounding.
• Set the grounding point near the POD to shorten the distance
of grounding cables.
DANGER
Electric shock hazard
Shut the power off before connecting the power supply cable.
