Acceptance Criteria
01
System configurations
The system configurations, including models
and the number of modules, comply with the
contract.
02
Cable routing
Cables outside the cabinets are properly routed
and arranged neatly without jump cables or
suspending cables. Cables are routed based on
the drawing.
03
Secure cable connections
Input and output power cables and battery
cables are securely connected, and spring
washers have been flattened to prevent them
from falling off and causing accidents. There is
no risk of disconnection.
04
Marks for tightened screws
Tightened screws are marked.
05
Signal cable connections
Signal cables are connected properly and
securely.
06
Cable labels
Both ends of each cable are labeled. Labels are
easy to understand.
07
Ground cable connections
The ground cable is securely connected to the
equipment room ground bar. Use a multimeter
to measure the resistance between the UPS
ground cable and the equipment room ground
bar. The resistancemust be less than 1 ohm.
08
Distances between cable ties
Distances between cable ties are the same
(recommended distance is 30 cm), and no burr
exists.
09
Correct cable connections
Cables are properly connected according to
wiring diagrams.
10
Input and output cable
connections
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.
11
Battery input connections
The positive and negative battery input
terminals, and battery N are connected
correctly.
12
Phase sequence of live wires
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.
13
Battery strings
Use a multimeter to check that the sum of the
absolute voltage of the negative battery string
and the voltage of the positive battery string is
