Inverters 12v dc to 240v ac

5.4 Connections

Ground Wiring
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 may result.

DC Wiring

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 securely.

STEP 3 - Connect the cable from the negative (black) 2500W INVERTER to the negative terminal of the battery. Make a secure connection.

CAUTION! Loose connectors result in excessive voltage drop and may cause overheated wires and melted insulation.
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 cables.

8 Maintenance

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.
