Connecting to an Existing AC Circuit
3–7
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 3-1 .
3. Remove the knockout on the DC end of the inverter.
4. Feed 3-conductor 14 AWG AC cable through the hole.
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 3-1 .
Ensure that you have maintained correct polarity and that there are no
loose strands of wire.
8. Replace the inverter’s bottom panel.
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.
