tion before
Operation
Check the following before operation:
1) Check whether the connection is correct.
For single-phase 200V series, check whether the power supply is
connected correctly to the L1/L and L2/N terminals. Also check
whether the inverter grounding terminal
G is securely connected.
2) Check for short-circuits and ground faults between terminals and be-
tween live parts.
3) Check for loose terminals, connectors, and screws.
4) Check whether the motor is separated from mechanical equipment.
5) Set switches to OFF before turning on the power so that the inverter
will not start or operate abnormally at power-on.
6) Check the following after power-on:
a) Check for alarms displayed on the keypad panel.
1. Always install the surface cover before turning on the power.
Do not remove the surface cover during conduction.
Otherwise electric shock could occur.
2. Do not operate a switch with wet hands.
Otherwise electric shock could occur.
