The 2500W INVERTER has a lug on the rear panel. This is to connect
the chassis of the 2500W INVERTER, 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 2500W INVERTER
is connected to the chassis.
The chassis ground lug must be connected to a grounding point,
which will vary depending on where the 2500W INVERTER 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 entrance 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 2500W INVERTER AC output
circuit is connected to chassis ground. Therefore, when the chassis
is connected to ground, the neutral conductor will 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 ground in the same way that
the neutral conductor from the utility line is tied to ground at
the AC breaker panel.
WARNING! Do not operate the 2500W
INVERTER without connecting it to ground. Electrical shock hazard
STEP 1 -Ensure that the ON/OFF switch on the 2500W INVERTER
is in the OFF position. If you are using a battery selector switch,
switch it off as well.
STEP 2 - Connect the cables to the power input terminals
on the rear panel of the 2500W INVERTER. The red terminal is positive
( +) and the black terminal is negative (- ) Tighten the wire connections
STEP 3 - Connect the cable from the negative (black) 2500W
INVERTER to the negative terminal of the battery. Make a secure
CAUTION! Loose connectors result
in excessive voltage drop and may cause overheated wires and melted
STEP 4 - Before proceeding further, carefully check that
the cable you have just attached connects the negative terminal
of the 2500W INVERTER to the negative terminal of the battery. Power
connections to the 2500W INVERTER must be positive to positive and
negative to negative.
CAUTION! Reverse polarity connection
(positive to negative) will blow the fuses in the 2500W INVERTER
and may permanently damage the 2500W INVERTER. Damage caused by
reverse polarity connection is not covered by your warranty.
CAUTION! We recommend a Main Fuse in the
battery positive cable to protect against dc wiring short circuits
(external to the inverter). The fuse should be as close to the battery
as possible. We recommend an approved class R or class J fuse, such
as Bussmans JJN or FRN, Little fuses JLLN or FIN or equivalent.
The specific fuse ampere rating should be sized to allow operation
of all your dc powered equipment and to properly protect your battery
Very little maintenance is required to keep your
2500W INVERTER operating properly; You should clean the exterior
of the unit periodically with a damp cloth to prevent accumulation
of dust and dirt. The air intake on the rear panel and air exhaust
slots on the front panel are especially prone to dust and dirt
accumulation. A regular maintenance check is recommended, and
the screws on the DC input terminals should be tightened periodically.
