A user supplied remote option is available for both the GPSW150 and GPSW300 inverters. When the ON / OFF switch is moved to the remote setting, the inverter becomes operational only when a connection is made between the two terminals of the remote input. A switch may be placed between the two terminals and the inverter can then be turned off using the switch. A ⅛” (3.0 mm) precision screwdriver is recommended for tightening the two terminals. It is recommended that a #18 gauge wire no longer than 150 feet (45.72 m) (terminal to terminal) is used for this application.
