Operation Method
Expected Result
Phase
sequence
Verify the phase sequences of
upstream and downstream power
distribution devices of the
FusionModule1000 using a phase
sequence meter.
The phase sequences are
consistent.
Voltage
Measure the voltage at the ATS
input end using a multimeter.
The voltage is in the range
of 342-456 V.
Frequency
Measure the frequency at the ATS
input end using a multimeter.
Frequency range for the 50
Hz scenario: 49-51 Hz
Frequency range for the 60
Hz scenario: 59-61 Hz
Battery
Check the number of batteries.
Check battery connection.
Measure the battery cell
voltage using a multimeter.
Measure the battery string
voltage using a multimeter.
The batteries are correct in
quantity and intact.
Batteries are connected
based on the design
requirements and installed
securely. Battery electrodes
are correctly connected.
The voltage is within the
rated voltage range of
batteries. The battery string
voltage is the single battery
voltage multiplied by the
number of batteries.
The voltage measurement
result meets the
requirement of system
power backup.

Phase
sequence of
indoor and
outdoor unit
cables
Verify that the L1, L2, L3, N, and
PE wires are connected for the
indoor and outdoor units in the
correct phase sequence using a
phase sequence meter.
The phase sequence is correct.
Water refill
for the air
conditioner
humidifier
Check whether the water refill
valve is open, and whether the
water refill pressure meets the
requirement.
The water refill valve is open,
and the water refill pressure is
0.1-0.7 MPa.
Water refill
from the
automatic
water refill
valve
Check whether the water refill
valve is open, and whether the
water refill pressure meets the
requirement.
The water refill valve is open,
and the water refill pressure is
greater than 0.15 MPa.
