Switch various switches, change wiring and perform inspections at least 10 minutes after the
power supply has been shut off; after confirming that the Operator is OFF and that a tester or
similar tool has been used to confirm that the voltage between the main circuit terminals P(+)
and N(-) has dropped to a safe voltage (25 VDC or less).
There is a risk of severe injury due to electric shock.
Wiring work must be carried out only by qualified personnel. Do not touch cables when the

Do not touch the cooling fins, braking resistors and the motor, which become too hot during
the power supply and for some time after the power shut off.
Doing so may result in a burn.
Inspection of the inverter must be conducted after the power supply was turned off.
Not doing so may result in a serious injury due to an electric shock.
The main power supply is not necessarily shut off even if the safety stop function is activat-
