Set the battery circuit breaker I1.
1
If the load of a single battery cabinet is greater than 50 kW and less than or
equal to 100 kW, set I1 to the MED position.
2
If the load of a single battery cabinet is less than or equal to 50 kW, set I1 to
the MIN position

Appearance
•
The following figure shows how to connect a communications cable between the
SmartLi and the integrated UPS (COM: 6 pins).
•
Communications cables between the SmartLi and other UPS models (COM: 8 pins) are
connected using standard network cables.
•
If more than eight SmartLi cabinets are connected in parallel, a maximum of four 15 m
parallel communications cables are supported.

For W1 and W2, use any set of twisted-pair
cables and remove any excess wires. The same
goes for W3 and W4. Other redundant core
wires are cut off.

Press the open buttons on the left of battery modules and open the wiring terminal
covers. Check the insulation performance of the battery modules.
Set a multimeter to the DC voltage mode and measure the voltage between the
ground point and the positive and negative terminals of each battery module
respectively. If the readings are less than 6 V DC, the insulation is good. Otherwise,
contact technical support engineers.
Insulation performance test points (using
eight battery modules as an example)
4
Install copper bars and cables.
•
After removing the insulation cap from a power cable, install the cable
immediately to prevent the exposed terminal from touching the shell, which
may cause sparks or burns.
•
To avoid short circuit, do not insert tools such as screwdriver directly into
threaded holes of positive or negative terminals of the battery module.

Excessive bolts will be used as spare parts.
