Step 2 Connect the SPD fuses FU9 and FU10.
If an SPD indicator is green, the SPD is running properly. If an SPD indicator is red,
the SPD is faulty and must be replaced immediately.
Step 3 Turn on the upstream power switch for the combiner cabinet to power on the
cabinet. If the power indicator of the combiner cabinet is on, the cabinet is
powered on properly.
Step 4 Turn on the output disconnectors in the combiner cabinet one by one to power on
the corresponding loads.
Step 5 Use a multimeter to measure the output voltage and input voltage of each
branch, which should be the same.
