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.
