
Replace batteries only with the ones of the same or equivalent type. Improper battery
replacement may cause an explosion.
Cooling System

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
container may go out of control.

For detailed configurations of the cooling system, see the initial configuration parameter
manual for the solution in use.
Management System (Monitoring System)

Do not smoke or use open flame inside the container.

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.
Fire Extinguishing System

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 VESDA; otherwise, the
VESDA may be damaged.

During fire extinguishing system commissioning, disconnect the solenoid valve, and
insert the fire cylinder safety pin to prevent agent release by mistake.
