Step 4: Switch on all AC breakers of Line wires in AC input. If AC connection is detected and three phases are
matched with unit setting, they will work normally. Otherwise, the AC icon
will flash and they will not
work in line mode. Under this circumstance, you can switch wires of AC inputs from L2 phase and L3 phase.
Or you may exchange the LCD program 28 of P2 and P3 to solve this problem.
LCD display in L1-phase unit
LCD display in L2-phase unit
LCD display in L3-phase unit
Step 5: If there is no more fault alarm, the system to support 3-phase equipment is completely installed.
Step 6: Please switch on all breakers of Line wires in load side. This system will start to provide power to the
load.
Note 1:
To avoid overload occurring, before turning on breakers at
load side, it’s better to have
the whole
system in operation first.
Note 2:
There is some transfer time for this operation. Power interruption may happen to critical devices,
which cannot tolerate transfer time.
