CAUTION:
To prevent risk of electric shock, ensure that the
ground wire is properly earthed before operating this hybrid
inverter no matter whether the grid is connected or not.
Before connecting to AC utility, please install a
separate
AC
circuit breaker between the inverter and AC utility. This will
ensure that the inverter can be securely disconnected during
maintenance and fully protected from over current on the AC
input side.
NOTE1:
Although this inverter is equipped with a 250VAC/30A
fuse, it’s still necessary to install a separate circuit breaker for
safety consideration. Please use a 250VAC/30A circuit breaker
between inverter and AC utility.
NOTE2:
The overvoltage category of the AC input is III. It should
be connected to the power distribution.
5.2 Connecting to the AC Utility
Step 1:
Check the grid voltage and frequency with an AC
voltmeter. It should be the same as the “VAC” value on the
product label.
Step 2:
Turn off the circuit breaker.
Step 3:
Remove 8mm of the
insulation sleeve on three of the
conductors. Shorten phase L and
neutral conductor N by 3 mm.
Refer to chart 1.
Step 5:
Make sure the wires are
securely connected. The reference
tightening torque is 0.82 N.m.
Step 6:
For safe operation, please use a wire with a ring
terminal to connect grounding. Refer to Chart 3.
L→LINE (brown or red)
→Ground (yellow-green)
N→Neutral (blue or black)
Step 4:
Connect wires according to polarities indicated on the
terminal block. Be sure to connect PE protective conductor
( ) first.
WARNING!
It's very important for system safety and efficient
operation to use the appropriate cables for grid (utility)
connection. To reduce risk of injury, please use the proper
recommended cable size as below.
