Installation
NOTE:
Before installation, please inspect the unit. Be sure that
nothing inside the package is damaged.
Connect to Utility and Charge
Plug in the AC input cord to the wall outlet. The unit will automatically charge the
connected external battery even though the unit is off.
Connect External Battery
Step 1- Take away the cover of external battery terminal.
Step 2-
Following battery polarity guide printed near the battery terminal!
RED cable to the positive terminal (+);
BLACK cable to the negative terminal (-).
WARNING!
Please use the appropriate battery cable. Please refer to
Important
Safety Warnings Section
for the details.
Step 3- There are two terminal types.
Type 1: Screw battery cables to terminals with the M5 nuts. Do NOT place
anything between the flat part of battery terminal and the battery
cable ring terminal, or overheating may occur.
Type 2: Simply screw battery cables to terminal with flat screwdriver.
(See Fig. 1)
Step 4- Install a DC Breaker in a positive battery line. The rating of the DC
Breaker must be according to the inverter's battery current (50 Amp). Keep
the DC breaker off. (see Fig. 2)
Step 5- Connect battery cables to the external batteries.
Note:
For the user operation safety, we strongly recommend that you should use tapes
to isolate the battery terminals before you start to operate the unit.
1)Single battery connection(Refer to Fig. 2):
When using a single battery, its
voltage must be equal to the Nominal DC Voltage of the unit (see below Table 1).
2)Multiple batteries in series connection(Refer to Fig. 3):
All batteries must
be equal in voltage and amp hour capacity. The sum of their voltages must be equal
to the nominal DC Voltage of the unit.
3)Multiple batteries in parallel connection(Refer to Fig. 4):
Each battery's
voltage must be equal to the Nominal DC Voltage of the unit.
Step 6- Make sure to connect the polarity of battery side and the unit correctly.
Positive pole (Red) of battery to the positive terminal (+)of the unit.
Negative pole (Black) of battery to the negative terminal (-) of the unit.
Step 7- Put the covers back to the external battery terminals.
Step 8- Take the DC breaker on.

Problem Probable Cause Solution
Utility power is
normal but the unit
is in battery mode.
When power fails,
the backup time is
shorten.
No LED display on
the front panel when
the utility power is
normal.
AC input power cord is not
connected well.
Input breaker is activated.
The unit is overload.
Battery voltage is too low.
Battery capacity is not full
even after charge the unit
for at least 8 hours.
The unit is not turned on.
Battery is not connected
well.
Battery defect.
Battery voltage is too low.
Check AC input power
connection.
Reset the input breaker.
Remove some non-critical
loads.
Charge the unit at least
8 hours.
Check the date code of the
battery. If the batteries
are too old, replace the
batteries.
Press power switch to turn
on the unit.
Check the external battery
cable and terminal. Make
sure all the battery
connections to the unit are
all correct.
Replace the batteries.
Charge the unit at least
8 hours.
