Check if the PVS can operate normally after installation:
Step 1
Connect the connection terminal of each PV string.
Step 2 Measure the input voltage of positive pole and negative pole of each input
to make sure they are basically same and the positive pole and negative pole
are connected correctly.
Step 3
Fasten the fuse holder.
Step 4
Close circuit breaker; monitoring unit power indicator “PWR” lights up and
status indicator “RUN” flashes. When push switch K2 is pressed, if there is a
value on the LED digitron, the operation is normal.
Step 5
Lock the door, remove the key and tighten the key-hole water-proof cover.
