Check Operation Method
Item
Phase Verify the phase sequences of
sequence upstream and downstream power
distribution devices of the
FusionModule1000 using a phase
sequence meter.
Voltage Measure the voltage at the ATS
input end using a multimeter.
Frequency Measure the frequency at the ATS
input end using a multimeter.
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.
Phase Verify that the L1, L2, L3, N, and
sequence of PE wires are connected for the
indoor and indoor and outdoor units in the
outdoor unit correct phase sequence using a
cables phase sequence meter.
Water refill Check whether the water refill
for the air valve is open, and whether the
conditioner water refill pressure meets the
humidifier requirement.
Water refill Check whether the water refill
from the valve is open, and whether the
automatic water refill pressure meets the
water refill requirement.

5 Items to Be Checked Before Power-On
Expected Result
The phase sequences are
consistent.
 The voltage is in the range
of 342-456 V.

Frequency range for the 50
Hz scenario: 49-51 Hz
 Frequency range for the 60
Hz scenario: 59-61 Hz
 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.
The phase sequence is correct.
The water refill valve is open,
and the water refill pressure is
0.1-0.7 MPa.
The water refill valve is open,
and the water refill pressure is
greater than 0.15 MPa.
