(3) Changeover switch description
Refer to page 5 for the location of the switches.
- Adjustment of the switch must be done during power off. Otherwise there is a risk of electric shock.
- Power ON must be done after closing the front cover. Do not open the front cover during power up, or when there is a remaining voltage.
There is a risk of electric shock.
