Test Running

1. Turn on all the DC wiring switches, and confirm that "d-47" is displayed on the LCD display. If "d-
47" is not displayed, the DC connections are incorrect. Check the polarity of all the DC wiring.
2. Turn off the AC&DC disconnect switches, and wait for 5 minutes to avoid the risk of electric
shock.
3. 5 minutes after the AC&DC disconnect is turned off, insert the GDFI fuse to the fuse socket. And
then turn on the AC&DC disconnect switches.

MODE" buttons of the solar power conditioner display simultaneously. Then "CLEAR" will be

may be blown because some of the DC connections are incorrect. Check the polarity of all the DC
wiring.
