Expected Result
● The lithium batteries are
correct in quantity and
intact.
● Lithium batteries are
connected based on the
design requirements and
installed securely.
Lithium battery
electrodes are correctly
connected.
● The voltage is within the
rated voltage range of
lithium batteries. The
battery string voltage
equals 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.
Outdoor unit air intake and
exhaust vents are not
blocked.
All smart cooling product
compressor pads are
removed.
