3. The battery neutral wire (if any) is correctly connected.
Short-circuit at
Check whether there is a short circuit between the positive, neutral, and
the upstream and
negative cables for circuit breakers, between copper bars, and between the

Power-On
•
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.
Status of Indicators on the BCU
The green indicator blinks at 4 Hz (at short intervals).
The green indicator blinks on for 1s and off for 4s
(intermittently).
The green indicator blinks at 10 Hz (blinking at super
short intervals), and the red indicator is steady on.
The green indicator blinks at 1 Hz or is steady on
(blinking at long intervals).
Communicating with the UPS
The UPS supports communication with SmartLi 3.0 and a communications cable is correctly
connected between the UPS and the SmartLi.
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.
•
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.
2. Obtain authorization on the battery cabinet.
3. Set the language, time, date, cloud service, network parameters, system
parameters, and alarm parameters on the Settings Wizard screen of the SmartLi.
