• 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.

Remove the front cover of the battery
8+8 scenario (example)
module, install the battery baffle
plate, and tighten the two screws.
Check the insulation performance of
the battery module. Set a multimeter
to the DC voltage mode and measure
the voltage between the positive and
negative terminals of each battery
module and the screws on the
battery baffle plate respectively. If
the readings are less than 6 V DC,
the insulation is good. Otherwise,
contact technical support engineers.
Place the front covers
properly to prevent the
light pipes from falling off.
