Do not tin the cable ends with solder. Doing so will
result in a poor long-term connection.
A solid, low resistance connection to the DC power
source is essential for proper operation.
The other ends of the cables, which are connected to the battery,
must be terminated with battery terminals that clamp to the posts on
the battery.
5.4 Connections
5.4.1 AC Wiring
You can plug your AC loads directly into the receptacles on the
inverter front panel. Output power to each receptacle is limited
by a circuit breaker, to 1500 Watts (15A).
You may also make a permanent AC connection via the AC
knockout. This connection must be made in accordance with
applicable electrical codes. If you are not familiar with the
applicable electrical codes and wiring practices, we
recommend you have the inverter installed by a qualified
electrician.
5.4.2 Ground Wiring
The Portawattz 3000 has a lug on the rear panel. This is to
connect the chassis of the Portawattz 3000, and therefore the
inverter’s AC output ground, to your AC distribution system
ground. The ground wire in the AC junction box on the front
panel of the Portawattz 3000 is connected to the chassis.
The chassis ground lug must be connected to a grounding
point, which will vary depending on where the Portawattz 3000
is installed. In a vehicle, connect the chassis ground to the
chassis of the vehicle. In a boat, connect to the boat’s
grounding system. In a fixed location, connect the chassis
ground lug to earth ground by connecting to a ground rod (a
metal rod pounded into the earth), or other proper service en-
trance ground. Use a #8 AWG or larger copper wire (preferably
with green/yellow insulation) to connect the chassis ground lug
to the grounding point.
The neutral (common) conductor of the Portawattz 3000 AC
output circuit is connected to chassis ground. Therefore, when
the chassis is connected to ground, the neutral conductor will
also be grounded. This conforms to National Electrical Code
requirements that separately derived AC sources (such as
inverters and generators) have their neutral conductors tied to
