and Output connection and that the DC disconnect switch is turned OFF.
The AC Output connection has three types of configurations:
1) Use of the provided GFCI AC socket for AC load:
This configuration does not require AC Output installation. Plug in the AC load to the provided
GFCI output socket. During the by-pass mode, the AC output is limited to 15A for 1000W
model (IC121040) and 20A for 2000W model (IC122055).
2) Hardwire AC Output with GFCI protection:
This configuration is for AC hardwire connection with a load that requires GFCI protection.
During by-pass mode, the AC output is limited to 15A for 1000W model (IC121040) and 20A
for 2000W model (IC122055).
• Remove AC compartment cover located on the front panel of the unit.
• Hardwire the AC load to the AC Output port 2. Please verify the ‘L’ and ‘N’ connection
between the AC load and the AC Output port.
3) Hardwire AC Output without GFCI protection:
This configuration is for AC hardwire connection with a load that does not require GFCI
protection and maximizes the by-pass mode current to the rating of the branch breaker
installed (maximum 30A).
• Remove AC compartment cover located on the front panel of the unit.
• Hardwire the AC load to the AC Output port 1. Please verify the ‘L’ and ‘N’ connection
between the AC load and the AC Output port.
Note: During Battery Power Mode, all AC output is limited to 8.3A for 1000W model (IC121040)
or 16.6A for 2000W model (IC122055).
Remote Display Connection:
• The Remote Display on the unit is detachable. To install the remote to different location, an
optional 6 pin standard RJ12 cable (not provided) is required.
• Remove the 2 screws at the front of the Display Panel and remove the small RJ12 cable.
• Install the optional RJ12 standard cable to your desired location. Please note polarity.
• Connect one end of the RJ12 cable to the unit and the other end of the cable to the Display
Panel. Please note polarity.
Test the Inverter-Charger connection:
• Switch DC disconnect switch to ON.
• Switch the Branch circuit breaker to ON.
• The LED on display will turn on. If AC input source is available, ‘Status’ LED turns green. This
indicates the unit is running in by-pass mode meaning AC output is running from the AC input
source.
• LED located at the GFCI will also turn ON
• Disconnecting the AC input source by turning OFF the 30A branch breaker will change the
‘Status’ LED on the Display to amber.
• Both AC output and 5V USB are now available.
• Plug in a small AC load like a 40W table lamp or small appliance to the AC socket to verify AC is
available.
• The unit is successfully installed and functioning properly.
Test the GFCI monthly:
• Use the following instruction to perform a monthly test of the GFCI to ensure the GFCI is
functioning properly.
• Turn unit on and plug a small AC load (e.g. 40W light bulb) to the GFCI.
• Check that the AC load is ON.
• Press ‘Test’ button and observe a clicking sound. Check that the AC load is turned off.
• Press ‘RESET’ button and check that the AC load is back ON again.
