1 O&M Precautions
Power Supply and Distribution System
Before replacing a component, ensure that the component and its battery are powered
off.
When operating power distribution equipment, follow the local regulations and rules.
When performing high-voltage and AC operations, use dedicated tools and wear
protection equipment.
Before entering the power supply area, check the hydrogen density and take protective
measures.
Do not install or remove power cables for a device which is powered on. Transient
contact between the core of the power cable and the conductor may generate electric arcs
or sparks, which may cause fire or hurt human eyes.
Before removing component cables, mark the cables with their corresponding port
numbers for later connection.
Before connecting a power cable, check that the label on the power cable is correct.
Assess impact on the system before switching off the general circuit breaker or cutting
off the cooling system during parts replacement.
For the detailed power control relationships between devices, see the power distribution
system diagram.
During battery O&M, observe the following:
Insulate tools before battery O&M.
Assign only professional engineers to perform the O&M.
Do not use any organic solvent to clean batteries.
Do not remove the safety valve or fill anything into batteries.
Do not smoke or use fire around batteries.
Do not place tools on bare batteries terminals.
Do not short-circuit the terminals of lead-acid batteries; otherwise, a fire may occur.
Do not maintain batteries online. Replace a battery if it is faulty.
Charge the battery within 24 hours after battery discharge; otherwise, the battery
capacity will be affected.
Do not open lead-acid batteries as electrolyte leakage may cause bodily 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.
Cooling System
Assign only professional engineers to perform O&M for the cooling system.
Do not block the air exhaust and return vents of air conditioners.
Promptly put serviced units into use after the cooling system is maintained; otherwise,
equipment cannot work at optimal status.
If the number of running air conditioners 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 guide.
Management System (Monitoring System)
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 IDS1000 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 guide for the solution in use.
Fire Extinguishing System
Do not smoke or use open flame inside the container.
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.
