Acceptance Criteria
1. The cabinet is correctly connected to the UPS.
2. Battery cabinets in parallel are correctly connected.
NOTE
When ensuring that the SmartLi and UPS are not powered on:
● If cabinets are installed close to each other, use a multimeter to check
whether the copper bars of the corresponding polarity in the adjacent
cabinets are conducted to verify the wiring polarity.
● If cabinets are installed far away from each other, short-circuit any
wiring copper bar and PE (enclosure) in one cabinet, and use a
multimeter to check whether the copper bar of the corresponding
polarity in another cabinet are conducted with PE (enclosure) to verify
the wiring polarity. Before the copper bar in cabinet 1 is short-circuited
with PE, the copper bar of the corresponding polarity in cabinet 2
should not be conducted with PE. After the copper bar in cabinet 1 is
short-circuited with PE, the copper bar of the corresponding polarity in
cabinet 2 should be conducted with PE. After the check is complete,
remove the cable between the copper bar and PE.
3. The battery neutral wire (if any) is correctly connected.
Check whether there is a short circuit between the positive, neutral,
and negative cables for circuit breakers, between copper bars, and
between cables and ground. If there is a short circuit, check whether
the cables are damaged or short-circuited. If yes, repair the cables.
If the pressure gauge pointer at the front door of the cabinet is
obviously lower than the initial position, contact Huawei technical
support.
The inside and outside of the cabinet are free from conductive dust
or other sundries.
1. There is no foreign matter (such as copper wires and screws) on
the top of the cabinet.
2. There is no foreign matter on the copper bar terminals.
3. There is no foreign matter around circuit breaker terminals.
4. There is no foreign matter on the bottom plate of the cabinet.
5. There is no foreign matter on the rear module subrack.
All the covers are reinstalled after checks are performed.
After the installation is complete, do not store the equipment in an
environment where the temperature and humidity are
uncontrollable for a long period of time. Otherwise, the equipment
may be damaged due to condensation.
The battery cabinet output cables are intact. The insulation
resistance of the positive, negative, and neutral output cables to the
ground and that between the positive, negative, and neutral output
cables are greater than 2 megohms (using a 500 V megohm meter).
