Power Supply Cable Connection
Connect the power supply cable to the terminal on the backside of the unit.
Power Supply Cable Specifications
For information on specifications of the power supply cable and the tightening torque of the screws
on the power supply terminal block, refer to the following table.
Notes on the Power Supply:
•
Power supply must be within allowable voltage fluctuations.
•
Use power supply 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 power supply cables away from high-voltage, large-current carrying cables.
Grounding
•
An independent grounding must be used for MONITOUCH.
•
Use a cable which has a nominal cross section of more than 2 mm
2
for grounding.
•
Set the grounding point near MONITOUCH to shorten the distance of grounding cables.
DANGER
Electric shock hazard
Shut the power off before connecting the power supply cable.
