ANTSPACE HK3 Water cooling container & Dry-Wet Tower Product Manual

PLC, QFP2 and QFPZ2 are switches for system 24V power supply, QFP3 and QFPZ3 are switches
for 12V power supply, and QFP4 and QFPZ4 are switches for 5V power supply. After powering on,
the screen and PLC on the cabinet door begin to work.
When the main control cabinet door is closed and the system needs to be powered on, first
open all miniature circuit breakers and one molded case circuit breaker QFVF02 inside the cabinet,
then close the cabinet door and open QFWCU through the cabinet door operating handle. At this
point, the equipment has been powered on.
Trained electricians can operate the system through a touch screen, set parameters, modify
thresholds, change operating modes (automatic/manual), start and stop a certain motor separately,
or operate automatically. At this point, the Water cooling system can be run first, and the supply
temperature can be controlled within the required temperature range before meeting the conditions
for starting the high computing power server.
2: After the main control cabinet is powered on, according to the operation process of the control
system, it is only when the Water supply temperature is maintained near the target temperature that
the high computing power server can be turned on. At this point, the circuit breakers in distribution
cabinets A and B can be opened to start powering on the high computing power server.
The power on sequence of the distribution cabinet is as follows:
First open MCB-A1 and A2, then other circuit breakers, and then start rows of high computing
servers in an orderly manner as required. Due to a total of 210 high computing power servers, there
are a total of 14 rows. When starting a high computing power server, the next row should be
started at an interval of 20 seconds after starting one row (15 high computing power servers), and so
on.
4) System Power-off Sequence
When the system needs to power off for some reason, as required, first disconnect the power
supply of the high computing power server to ensure that the water temperature before and after the
power outage is consistent, which is equivalent to protecting the power module of the high
computing power server. After the power outage of the high computing power server, the Water
cooling system is manually stopped through the touch screen. At this time, the water temperature
will slightly rise, but it has no impact on the system. Finally, disconnect the main power supply of
