INSTALLATION

CONTROL WIRING

More advanced installations will require additional wiring to interface the inverter to other components of the system. Proper installation is important to ensure the reliability of the system.

Although the circuits may carry little or even no actual power, the use of quality wire in conduit is recommended to provide good results. All circuits should also be fused at the source of the power in the circuit to provide both protection and indication of problems with the control circuit. Consult local code and the NEC for minimum wire size and type required based on the length that you want to run.

The AC circuit board provides male type push on connectors and you are provided crimp-on terminals in your hardwire package to connect to these Aux and Gen Control relays. These terminals allow easier connection of a variety of wire sizes and allow faster installation and troubleshooting. This circuit board also includes two LED indicators to allow visual indication of the generator control sequence provided by relays RY7 and RY8. These relays are not intended to directly control the starter motor or operate the ignition system - rather they can be used to send a signal or operate the coil of another higher amperage device which does the actual switching of the power.

CAUTION: A fuse rated at 5 amps or less must be included to protect each of the relays. Damage to these relays is not covered by the Warranty and requires the inverter to be returned to a service center for repair.

GEN CONTROL WIRING

The configuration of the starting relays on all SW Series inverters allows starting of both Honda and Onan type generators. The COM terminals of relay RY7 and RY8 are separated and both the normally open and normally closed contacts are provided.

It is much easier to make the connections to the generator if a remote control terminal or connector is available on the generator. This sometimes requires that the generator optional remote control panel be purchased. This allows examination of how the generator remote control panel works - which is what the inverter’s generator control system in the inverter must duplicate.

Connection of the inverter’s generator control relays in the inverter to the generator’s remote control panel also eliminates the need to make modifications and thus violate the generator’s warranty.

You should also ensure that there is a switch to allow disabling of the automatic generator control system at the generator. This will allow local control of the generator, preventing starting while servicing, etc.

AUX RELAY WIRING

The auxiliary relays are RY9, RY10, and RY11 and can be used to control external power sources or loads. The voltage settings that determine when the relays are activated are individually adjustable. The relays are connected to a terminal block located in the wiring compartment at the left end of the inverter and must be fused to prevent damage if they are miswired or a short-circuit occurs . The maximum fuse size must not exceed 5 amps and the fuses should be located as close as possible to the source of power e.g. generator battery.

REMOTE CONTROL WIRING

An optional remote control panel for the SW Series Inverter/Charger is available (Trace™ part number SWRC or SWRC/50FT) which provides complete duplication of the control panel on the front of the inverter. It is connected to the REMOTE PORT on the left side (AC side) of the inverter (see page 12 for the location of the REMOTE PORT) through a provided cable. Two cable lengths are available - 25 feet (8 meters) or 50 feet (16 meters). Distances longer than 50 feet (16 meters) are not recommended. The remote control cable should be kept away from sources of radio frequency interference such as motors and antennas. The cable must be protected from abrasion and hot surfaces.
