CAUTION:
It’s only allowed to connect the load to “AC Output
Connector”. Do NOT connect the utility to “AC Output
Connector”.
CAUTION:
Be sure to connect L terminal of load to L terminal of
“AC Output Connector” and N terminal of load to N terminal
of “AC Output Connector”. The G terminal of “AC Output
Connector” is connected to grounding of the load. Do NOT
mis-connect.
CAUTION:
This inverter is not allowed to operate in parallel.
Please do NOT parallel connect more than one unit in AC
output connector. This will damage this inverter.
WARNING!
It's very important for system safety and efficient
operation to use appropriately sized cable for battery connection.
To reduce risk of injury, please use the proper recommended
minimum cable size as below.

CAUTION:
Before connecting to the batteries, please install a
separate
DC circuit breaker between the inverter and the
batteries.
NOTE:
Use only sealed, vented or Gel lead acid batteries. Check
the minimum and maximum charging voltage and current when
first using this inverter. If using Lithium iron or Nicd battery,
please consult with the installer for the details.
NOTE:
Use a 60VDC/100A circuit breaker.
Follow the steps bellow to implement battery connection:
Step 1:
Check the nominal voltage of batteries. The nominal
input voltage for hybrid inverter is 48VDC.
Step 2:
Use two battery cables. Remove 12mm from the
insulation sleeve and insert the bare conductor into cable ring
terminal. Refer to Chart 6.
Step 3:
Following battery polarity guide printed near the battery
terminal! Place the external battery cable ring terminal over the
battery terminal. Refer to Chart 7.
RED cable to the positive terminal (+);
BLACK cable to the negative terminal (-).
Step 4:
Make sure the wires are securely connected. The
reference tightening torque is 2.04 N.m.

CAUTION:
To prevent further supply to the load via the inverter
during any mode of operation, an additional disconnection
device should be placed in the building wiring installation.
WARNING!
It's very important for system safety and efficient
operation to use appropriate cable for AC connection. To reduce
risk of injury, please use the proper recommended cable size as
below.
Step 1:
Remove 8mm from the insulation sleeve for three
conductors. Shorten phase L and neutral conductor N by 3 mm.
Refer to Chart 8.
Step 2:
Connect wires according to polarities indicated on
terminal block. Be sure to connect PE protective conductor (
Ground symbol to be inserted ) first. Refer to Chart 9.
L→LINE (brown or red)
→Ground (yellow-green)
N→Neutral (blue or black)
Step 3:
Make sure the wires are securely connected.
The reference tightening torque is 0.82 N.m.
