Expected Result
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 0.1 ohm.
Distances (recommended: 30 cm) between
cable ties are the same, and no burr exists.
Cables are properly connected according to
wiring diagrams.
The connections are correct. Connect the input
1L1, 1L2, 1L3, 1N, 2L1, 2L2, 2L3, and 2N
wires correctly. Connect the primary and
secondary ATS power cables correctly
In single UPS mode, mains and bypass input
and output live wires are connected in a
correct sequence.
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 or an insulation resistance
tester.
The surge protection switch is turned on.
The inside and outside of the cabinet, and
other operating components, are free from
conductive dust.
