1 Operation and Maintenance 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 entering the power supply zone, verify that no hydrogen alarm is

displayed on the ECC800 or NetEco LCD.● Before replacing a component which is not hot swappable, you must switch

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

● Assess impact on the system before switching off the general circuit breakeror 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 conductormay generate electric arcs or sparks, which may cause fire or hurt humaneyes.

● Before removing component cables, mark the cables with their correspondingport numbers for later connection.

● Before connecting a power cable, check that the label on the power cable iscorrect.

● For the detailed power control relationships between devices, see the powerdistribution system diagram for the solution in use.

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.● Never smoke or use fire around batteries.● Do not place tools on bare batteries terminals.● Do not short-circuit the terminals of batteries; otherwise, a fire may occur.● Do not maintain batteries online. Replace a battery if it is faulty.

Issue 04 (2021-02-10) Copyright © Huawei Technologies Co., Ltd. 1

● Charge the battery within 24 hours after battery discharge; otherwise, thebattery capacity will be affected.

● Do not open batteries as electrolyte leakage may cause personal injuries. Ifyou contact the electrolyte accidentally, immediately clean your skin withwater and seek medical advice from a doctor.

● Replace batteries only with the ones of the same or equivalent type. Improperbattery 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 therated 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 configurationparameter manual for the solution in use.

Management System (Monitoring System)● Do not smoke or use open flame inside the pre-fab. module.

● Assign only professional engineers to perform O&M for the managementsystem.

● Routine maintenance for the management system is critical for long-termstable and efficient operation of the FusionModule1000 because most alarmsare reported over the management system.

● Promptly handle reported alarms to prevent equipment damage or serviceinterruption.

● Check and calibrate the hydrogen detection equipment sensors half a yearwithin the sensor service life (less than 5 years).

● For detailed initial configurations for the management system, see the initialconfiguration 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 tomaintenance. In addition, disable the logical control function of the area orsystem to prevent false alarms. Inform the related departments of the systemrecovery after the maintenance is complete.

● Take antistatic measures before removing the front panel from a ASD;otherwise, the ASD may be damaged.



● During fire extinguishing system commissioning, disconnect the solenoidvalve, and insert the fire cylinder safety pin to prevent agent release bymistake.
