Install the 6-pin RJ12 cable in your desired location and connect the RJ12 cable to the unit
and the other end of the cable to the Display Panel. See appendix II for more details.
Test the Inverter Connection:
Turn the DC disconnect switch ON to provide battery power to the unit.
Turn the external AC Branch Breaker ON to provide AC Input power to the unit. The display on
the panel should turn on automatically showing "888" briefly, then the software revision
number of the detachable panel and the main unit (e.g. "r0.4" and "u1.6" respectively), before
finally passing from the initiation routine to normal operation showing the battery voltage and
providing AC-Output power.
Once the display starts showing the battery voltage (with AC-Input power available) the
'Status' LED will turn green to indicate that the unit is in Bypass mode, which means the AC
output is running from the AC input source. If the unit is set to "PS1 ("factory default) it will take
about 20 sec for entering Bypass mode. In that case, meantime the "Status" LED remains
flashing amber to indicate the unit is running in Battery (Inverter) mode and is going to pass to
Bypass soon (within a 20 sec period). If the unit is set to "PS4", it has to be turned on manually
by pushing the "Power" button (see Feature Setting section for more details).
Once the "Status" LED goes solid green, disconnect the AC input source by turning the exter-
nal AC Input Branch Breaker OFF. Doing so, the 'Status' LED on the display changes immedi-
ately from solid green to solid amber, to indicate the unit is running in Battery (Inverter) mode.
Both AC output and 5V USB are now available and the unit is running on battery power.
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: (120V model only)
Use the following instruction to perform a monthly test of the AC Output GFCI Socket to ensure
the GFCI is functioning properly.
Turn the unit on and plug a small AC load (e.g. a light bulb) to the AC Output GFCI Socket.
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.
4. UNIT OPERATION
Auto Backup Mode (whatever "PS" setting except "PS0"):
The unit is fully automatic. When utility power is available, the unit is running in AC Bypass mode.
AC output is supplied from the utility. When there is a power failure from the utility or an AC
source is not available, the unit will run on battery power and the inverter will generate sinewave
AC output to maintain and operate the load continuously (With 'PS2' setting, there is a minimum
of 10W AC-Load sense threshold for the inverter to fully turn on).
Non-Backup Mode (with "PS0" setting)
Same as Auto Backup Mode but when there is a power failure from the utility or the AC input
source is not available; the inverter will not turn ON automatically. To turn the inverter on, you
have to get into the setting mode and change the "PS" setting from "PS0" to "PS1" or others.
