Charge the battery within 24 hours after battery discharge; otherwise, the
battery capacity will be affected.
Do not open batteries as electrolyte leakage may cause personal injuries. If
you contact the electrolyte accidentally, immediately clean your skin with
water and seek medical advice from a doctor.
Replace batteries only with the ones of the same or equivalent type. Improper
battery replacement may cause an explosion.
Assign only professional engineers to perform O&M for the cooling system.
Do not operate valves of the cooling system arbitrarily.
Do not block the air exhaust and return vents of smart cooling products.
Promptly put serviced units into use after the cooling system is maintained;
otherwise, equipment cannot work at optimal status.
If the number of running smart cooling products in an area is less than the
rated minimum number, some loads must be powered off; otherwise,
temperature inside the pre-fab. module may go out of control.
For detailed configurations of the cooling system, see the initial configuration
parameter manual for the solution in use.
Do not smoke or use open flame inside the pre-fab. module.
Assign only professional engineers to perform O&M for the management
system.
Routine maintenance for the management system is critical for long-term
stable and efficient operation of the FusionModule1000 because most alarms
are reported over the management system.
Promptly handle reported alarms to prevent equipment damage or service
interruption.
Check and calibrate the hydrogen detection equipment sensors half a year
within the sensor service life (less than 5 years).
For detailed initial configurations for the management system, see the initial
configuration parameter manual for the solution in use.
Assign only qualified engineers to perform O&M for the fire extinguishing
system.
Before performing routine maintenance for the fire extinguishing system,
inform the related departments of the temporary downtime due to
maintenance. In addition, disable the logical control function of the area or
system to prevent false alarms. Inform the related departments of the system
recovery after the maintenance is complete.
Take antistatic measures before removing the front panel from a ASD;
otherwise, the ASD may be damaged.
