Expected Result
washers are flattened, prevent falling off and
safety accidents. Ensure that there is no
disconnection or potential risk.
Signal cables are connected properly and
securely.
Both ends of each cable are labeled. Labels
are easy to understand.
The ground cable is securely connected to the
equipment room ground bar. Measure the
resistance between the UPS ground cable and
the equipment room ground bar, which must
be less than 1 ohm.
Distances between cable ties are the same, and
no burr exists.
Cables are properly connected according to
wiring diagrams.
Input and output live wires and neutral wires
are correctly connected. Mains input terminals
1L1, 1L2, 1L3, and N, bypass input terminals
2L1, 2L2, 2L3, and N, and output terminals U,
V, W, and N are properly connected.
In single UPS mode, mains and bypass input
and output live wires are connected in a
correct sequence; in a parallel system, mains
and bypass input and output live wires are
connected in the same sequence for each UPS.
Check that the voltages on the positive and
negative battery terminals and battery N are
correct using a multimeter.
Clean the conductive air and other sundries.
Check that copper busbars are open-circuited
using a multimeter.
