Installation

WARNING: Risk of electrical shock or fire.

The PROwatt SW Inverter does not come with a DC-rated fuse (or circuit breaker) to safely withstand the short- circuit current batteries can produce. To avoid the risk of electrical shock or fire, install a DC-rated fuse (and fuse holder) on the positive battery terminal.

3.Install a DC-rated fuse on the positive battery terminal.

Alternatively, install a DC-rated circuit breaker that connects to the positive battery terminal.

The fuse (or circuit breaker must have an Ampere Interrupting Capacity (AIC) that exceeds the short-circuit current available from the battery. For guidance, see “Cold Cranking Amps / AIC” on page 11.

4.When configuring for heavy loads (see Figure 5), install a battery selector switch and connect it to the DC-rated fuse (or circuit breaker).

5.On the inverter side, attach the connectors of the positive and negative cables into the cabling terminals of the inverter.

Note: Make a secure connection. Loose connectors cause excessive voltage drop and may cause overheated wires and melted insulation.

Note: The red terminal is positive (+) and the black terminal is negative (–). Power connections to the PROwatt SW Inverter must be positive to positive and negative to negative.

CAUTION: Risk of inverter damage due to reverse polarity.

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.

6.Attach the connector on the positive cable to the DC-rated fuse (or circuit breaker) which is connected to the positive terminal of the battery.

When configuring for heavy loads (see Figure 5), attach the connector on the positive cable to the battery selector switch that is already connected to the DC-rated fuse (or circuit breaker).

Note: Make a secure connection. Loose connectors cause excessive voltage drop and may cause overheated wires and melted insulation.

WARNING: Risk of 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.
