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 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 for the solution in use.
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.
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.
