TC500K3US-O Installation Instructions
87
Check the DC voltage
DC shall connect combiner box to the inverter DC input terminals.
Ensure the DC input polarity is correct.
Measure and record the voltage of each DC (open circuit). The voltage
value of each phase shall be almost the same, and do not exceed the
allowable maximum DC voltage.
TC500K3US-O DC voltage shall not exceed 600Vdc. Very high DC
voltage will damage the inverter.
10.3 Preparing before Power on
Ready to power on when all the items have been checked and all has been
confirmed to meet the requirements.
Step 1
Make sure the grid line voltage is 200Vac again.
Step 2
Make sure that no person is operating the inverter inside and
outside cabinet.
Step 3
Install all the screws to its original position which are removed
when wiring, and then shut the front door of the cabinet, and lock the door.
