(Do not use your finger or any metallic object.)
2. Never turn on the power supply unit until all installation work has been completed.

4. Check that the voltage is -10% of the rated voltage (198V, 1 phase or 342V, 3 phase) or higher when starting the unit.
The unit will not operate if the voltage is less than -10% of the rated voltage (198V, 1 phase or 342V, 3 phase).
5. If test operation continues for more than 30 minutes, test operation finishes and shifts to normal operation.
