Connecting to an Existing AC Circuit
AC Wiring Procedure
To make a permanent connection to existing AC wiring:
1.Make sure no DC voltage is being supplied to the inverter, and make sure no AC voltage is present on the AC wiring.
2.Remove the bottom plate from the inverter. This gives you access to the AC terminal blocks. See Figure
3.Remove the knockout on the DC end of the inverter.
4.Feed
5.Insert a cable clamp for electrical junction boxes to hold the cable in place.
6.Connect the ground lead of the AC cable (green or bare wire) to the internal terminal block labelled AC GND. Connect the other end of the ground lead to a grounding point on a junction box or breaker panel. Make sure the ground lead is cut as short as possible and is not touching any component within the inverter.
7.Strip 1/4 inch (6 mm) of insulation from the line (black) and neutral (white) leads, and connect them to the AC output terminal blocks on the PROwatt 1000 circuit board. These terminal blocks are labeled AC HOT and AC NEUT respectively as shown in Figure
CAUTION: Reverse Polarity
Improper connections (connecting a line conductor to a neutral conductor, for example) will cause the PROwatt 1000 to malfunction and may permanently damage the inverter.
Damage caused by a reverse polarity connection is not covered by your warranty.
Ensure that you have maintained correct polarity and that there are no loose strands of wire.
8. Replace the inverter’s bottom panel.
