SHOCK AND FIRE HAZARD
Make sure wiring is disconnected from all electrical sources
n
before handling.
Do not connect an AC source (such as a generator or utility
n
power) to the AC wiring output of the XPower inverter
Potentially hazardous or damaging conditions may occur, if
n
its output is connected to an AC voltage from another source.
These conditions can occur even if the inverter is off. If
installing the XPower inverter in a system with another AC
source (utility power or generator), an approved and suitably
rated break-before-make AC transfer switch must be
installed.
Failure to follow these instructions can result in death, serious
injury, or equipment damage.
To make the AC output wiring connections:
1. Disconnect all DC power sources from the XPower Inverter
3000.
2. Install a dedicated AC load panel or an additional circuit
breaker in an existing AC load panel.
This circuit breaker must have a current rating based on the
975-0556-01-01
WARNING
load current the circuit will carry, and must be rated for 120
Vac branch circuits. For installations subject to the US NEC,
the required breaker size is 30 A based on No. 10 AWG
(using 75 °C minimum wire) and the 2500 W continuous
output rating of the inverter.
3. Remove the AC wiring knockout from the XPower inverter
AC panel.
4. Remove the screws securing the XPower inverter AC
panel.
5. Locate the white terminal block whose connectors are all
properly labeled – (L)ine, (N)eutral, and (G)round.
6. Prepare and strip the line, neutral, and ground (if not bare)
wires. Strip at a length of 0.35 inches (9 mm).
7. Install a strain-relief device (not provided) on the AC
knockout.
8. Run each of the line, neutral, and ground wires through the
knockout and through the strain-relief device.
9. Loosen the screws on the left side of the terminal block, if
not already loose at the factory. Be careful not to loosen the
right side screws.
