Installation
4.Install a fuse and fuse holder in the cable that will be used for the positive side of the DC circuit. The fuse must be as close to the battery as possible, be rated for DC circuits, and have an Ampere Interrupting Capacity (AIC) that exceeds the
5.Insert the stripped ends of the cables into the cabling terminals on the DC end of the inverter and tighten the screws securely. The red terminal is positive (+); the black terminal is negative
6.Attach the connector on the negative cable to the negative battery terminal. Make a secure connection. Loose connectors cause excessive voltage drop and may cause overheated wires and melted insulation.
CAUTION: Reverse Polarity
Power connections to the PROwatt 1000 must be positive to positive and negative to negative.
A reverse polarity connection (positive to negative) will blow a fuse in the inverter and may permanently damage the unit. Damage caused by a reverse polarity connection is not covered by your warranty.
7.Before proceeding, make sure that the cable you have just installed connects the negative terminal of the inverter to the negative terminal of the battery.
WARNING: Explosion or Fire
Do not complete the next step if flammable fumes are present. Explosion or fire may result. Thoroughly ventilate the battery compartment before making this connection.
8.Connect the cable from the positive (red) terminal of the PROwatt 1000 to the positive terminal of the battery.
This is the last cable connection. A spark is normal when you make it.
9.If you have installed a battery selector switch, use it to select one of the batteries or battery banks.
10.Turn on the inverter’s On/Off switch.
