1 O&M Precautions

Issue 04 (2018-01-05)

1 O&M Precautions

Power Supply and Distribution System

 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 replacing a component which is not hot swappable, you must switch off the

upstream circuit breaker, and verify that the component to be replaced is power off.

 Assess impact on the system before switching off the general circuit breaker or cutting

off the cooling system during parts replacement.

 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.

 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 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.

Management 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 FusionModule1000 because most alarms are reported over the

management system.

 Promptly handle reported alarms to prevent equipment damage or service interruption.

 For detailed initial configurations for the management system, see the initial

configuration parameter manual for the solution in use.

Fire Extinguishing System

 Do not smoke or use open flame inside the pre-fab. module.

 Assign only qualified engineers to perform O&M for the fire extinguishing system.

 Before maintaining the fire extinguishing system or its components, inform the related

administrative departments.

 During fire extinguishing system commissioning, disconnect the solenoid valve, and

insert the fire cylinder safety pin to prevent agent release by mistake.
