Power Cable Wiring
CAUTION
•
The power cable must be wired through a conduit at the entrance of the cabinet for the
following reasons:
•
To prevent the power cable from being damaged through direct contact with the met-
al plate.
•
To prevent an excessive load being applied to the power supply connection terminals
due to the weight of the cable itself.
•
Turn off the power supply source, and be sure that no electricity is flowing into the power
cable to be connected before starting the work.
•
After the power cable has been connected, turn on the power to the power cable with the
breaker in the power panel turned OFF. Then, confirm with a tester that normal power is
being supplied to the power input terminal.
•
Wire the power cable by keeping a minimum distance of 1 cm from other signal wiring.
