Installation

Read the entire Important Safety Information section at the beginning of this manual including all text under subheadings therein before set up or use of this product.

TO PREVENT SERIOUS INJURY FROM ACCIDENTAL OPERATION:

Make sure that the Power Switch is in the off‑position and unplug the tool from its electrical outlet before performing any procedure in this section.

Note: For additional information regarding the parts listed in the following pages, refer to Parts List and Diagram on page 11.

Maintenan

CAUTION! This Inverter must only be connected to batteries with a output voltage of 12 volts DC. Lower voltage will not operate the Inverter properly, and more voltage could damage the Inverter

or the device being powered. Do not use this Inverter with positive ground electrical systems.

The Inverter is configured to have a number of shut-down points, for the safety of the operator, the unit, and the devices being used with it.

•If the DC input voltage drops too low, the alarm on the Inverter will sound. Should the input voltage drop further, the Inverter will shut down automatically to prevent permanent battery damage. Recharge the battery soon.

•If the DC input voltage exceeds 15V the Inverter will shut down automatically.

•If the output load power rises higher than the rating power of the Inverter; the unit may shut down automatically.

•The Inverter may automatically shut down if its internal temperature gets too high.

Note: Even though this inverter has built-in mechanisms to minimize damage, these situations should be avoided because they can still damage the inverter or battery.

1.Place the Inverter on a dry, level, non-flammable, stable surface. Make sure the Inverter has adequate ventilation and is not in direct sunlight.

2.Connect one end of a ground wire (not included, use at least recommended wire thickness from specification sheet) to the wing nut located on the back of the Inverter. Then connect the other end of the ground wire to a paint/rust free grounded metal surface, such as the vehicle chassis.

3.Battery Type Selection:

•Use only deep cycle lead-acid batteries with this inverter, such as 12 volt marine/RV deep-cycle batteries. Do not use automotive, engine starting (SLI), or maintenance-free wet cell batteries with this inverter; they are designed for repeated, shallow discharge and will wear out quickly.

•Gel and AGM (Absorbed Glass Mat) batteries can be used with this inverter, but they require special charging procedures. Refer to battery supplier’s instructions.

4.Battery capacity selection:

	about 1 hour	about 4 hour
Inverter	discharge time	discharge time
Output	(Minimum battery	(Optimal battery
	capacity)	capacity)
500W	80 Ah	200 Ah
1000W	150 Ah	400 Ah
1500W	240 Ah	700 Ah
2000W	300 Ah	1000 Ah
3000W	450 Ah	1500 Ah
4000W	600 Ah	2000 Ah
5000W	750 Ah	2500 Ah

Consult the chart above for approximate run time at different battery capacities. If the battery does not have a capacity this large individually, use a bank of batteries as explained below.

5.Battery Bank assembly instructions:

a.Read the following safety rules before assembling the battery bank:

•Connect batteries in parallel (negative terminals together to one cable; positive terminals together to the other cable) as shown in Battery Bank Example illustration only.

•Do not connect 12V batteries in series (from negative of one battery to the positive of the next). This connection can result in voltage high enough to cause electrocution.

•Wear splash-resistant ANSI-approved safety goggles and electrically insulated gloves while assembling battery bank.

•Only connect similar batteries together in a battery bank. Do not connect old and new batteries together, wet and gel cells together, or batteries of different capacities together.

•Connect all batteries in the battery bank together using cables of the thickness recommended on the specification sheet or thicker. Since amp draw on this low-voltage circuit will be very high, thinner cables present a fire hazard.
