Installation/Operation
NOTE
n
Use a qualified installer or technician/electrician. Consult your RV/motor
home/vessel dealer for guidance.
n
Use stranded 14 AWG min. copper (CU) wiring only for AC connections.
1. Disconnect or turn off all power sources prior to installation.
2. Connect the
AC Output
(loads) cable to an input branch circuit such as a 15A
maximum circuit-protected load sub-panel in your RV or motor home/vessel.
3. Connect the
AC Input 1
cable to your PROwatt SW inverter
only
.
4. Connect the
AC Input 2
cable to a 15A maximum circuit-protected mains supply
output branch circuit such as a utility sub-panel in your RV or motor
home/vessel.
5. Turn on all power sources.

SPECIFIC CIRCUIT BREAKER MANUFACTURER AND TYPE LISTING
When the transfer switch is protected by a circuit breaker (of a specific manufacturer, type,
and ampere rating), determine the circuit breaker’s compatibility by making sure it is
suitable for use in circuits capable of delivering the short-circuit current at the maximum
voltage stated below:
• Short Circuit Current (RMS Symmetrical Amperes X 1000) : 10
• Voltage (Volts AC Maximum): 240
• Rating (Amperes): 15
