2.7.8 AC
Wiring
The 700 W Model comes either factory-wired or has the option of being
hardwired. The 1,000 W to 2,500 W Models require permanent, hardwired
connections.
Wiring must comply with local regulatory code for the
specifi c site.
WARNING: RISK OF FIRE
Ensure wire sizes comply with local regulatory code.
IMPORTANT:
• A circuit breaker or fuse is required on the hot AC line wire near the inverter.
• Refer to Section 2.7.2 for recommended AC circuit breaker/fuse ratings
• Refer to Section 2.7.3 DC and AC Power Wire Sizing Requirements for AC
wire sizing.
• Use a proper crimping tool to crimp the terminals to the bare ends of the wires
where required. Connections should be tight so they can’t slide out.
• There must be one and
only one AC neutral ground bond
. Do not install
The SureSine inverter with an external neutral-ground bond unless the internal
neutral-ground bond has been removed. Refer to Section 2.7.4.1 for details.
A three-conductor copper cable with at least a 75°C insulation rating can be
used for wiring the AC circuits.
2.7.8.1 AC Wiring Procedure
STEP 1.
Before wiring, verify that the AC Output Mode Switch is in
the Center/ OFF position, all breakers in the system are in the open/
disconnected position, and all fuses are removed from the holders.
STEP 2.
a. Connect the AC line wire between the AC Line terminal of the SureSine
inverter and the fuse or AC circuit breaker.
b. Then connect another wire between the fuse or AC circuit breaker and
the line connection of the AC receptacle or AC distribution panel.
STEP 3.
Connect the AC Neutral wire between the AC neutral terminal of
the SureSine inverter and the neutral connection of the AC receptacle or
AC distribution panel. Ensure that the distribution panel does not have a
neutral ground connection.
STEP 4.
Connect the earth/ ground wire between the Earth terminal of the
SureSine inverter and the earth ground connection of the AC device, AC
receptacle, or AC distribution panel.
