Verifying the Installation
Do not remove the dust cover
before power-on.
Item
Acceptance Criteria
Cabinet
installation
The cabinet is securely installed and does not tilt due to vibration.
Neat arrangement
The adjacent cabinets are neatly arranged and secured with connecting kits.
Cable layout
Cables are routed properly as required by the customer.
Cable labels
Both ends of a cable are labeled. Labels are concise and easy to understand.
Cable ties
Cable ties are secured evenly and no burr exists.
Cable or copper
bar connections
Battery cables or copper bars are securely connected, the spring washers are
crimped properly for cables secured by screws, and the cables are intact.
Grounding
The resistance between the cabinet ground bar and the equipment room
ground bar is less than 0.1 ohm.
Battery cable
connections
1.The cabinet is correctly connected to the UPS.
2.Battery cabinets in parallel are correctly connected.
3.The battery neutral wire (if any) is correctly connected.
Short-circuit at
the upstream and
downstream of
circuit breakers
Check whether there is a short circuit between the positive, neutral, and
negative cables for circuit breakers, between copper bars, and between the
cables, copper bars, and enclosure. If there is a short circuit, check whether
the cables are damaged or short-circuited. If yes, repair the cables.
Foreign matter
cleaning inside
the cabinet
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.
Cover installation
All the covers are reinstalled after checks are performed.
Storage
environment
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.
Insulation
resistance of
output power
cables
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).
Installation
protection
If batteries are not powered on after installation, take dustproof and anti-
condensation measures (for example, using a dust cover, plastic film, or
fabric cloth) to prevent battery condensation or dust corrosion. Remove the
protective material when batteries need to be used.
•
The BCB off alarm (the red indicator is steady on) is displayed on the SmartLi LCD. No action is
required. After the battery circuit breaker is switched on, the alarm will be automatically cleared.
•
The green indicator blinks intermittently. After 1 minute, the BCU starts. The green indicator blinks at
super short intervals and the red indicator is steady on.
1. Press and hold the POWER ON/OFF button on the BCU of the SmartLi cabinet for more than 2s. The
green indicator of the BCU blinks at short intervals.
Status of Indicators on the BCU
Description
The green indicator blinks at 4 Hz (at short intervals).
Status after the switch button is pressed.
The green indicator blinks on for 1s and off for 4s
(intermittently).
The SmartLi circuit breaker cannot be switched on,
and the UPS cannot be cold started.
The green indicator blinks at 10 Hz (blinking at super
short intervals), and the red indicator is steady on.
The SmartLi circuit breaker can be switched on, but
the UPS cannot be cold started.
The green indicator blinks at 1 Hz or is steady on
(blinking at long intervals).
The UPS can be cold started.
3. Set the language, time, date, cloud service, network parameters, system
parameters, and alarm parameters on the Settings Wizard screen of the SmartLi.
•
Turn on the ready switch on the BCU.
•
Ensure that the UPS runs stably in normal mode and the rectifier shown in the energy flow diagram is started.
