IS-485L Card

Figure 8-18 IS-485L card

The IS-485L card can be used to convert the UPS internal protocol to Modbus RTU protocol, enabling the user can
use the Modbus RTU protocol to manage the UPS, acquire the UPS parameters, operating status and fault types for
UPS monitoring purposes.
For more information about the IS-485L card, refer to the

Liebert IntelliSlot Modbus 485, Modbus IP And BACnet IP

Reference Guide

.

The installation procedure for the IS-485L card is the same as for the IS-WEBL card, as described in 8.1.5

IS-WEBL

Parallel Cables

Shielded and double-insulated parallel cables available in lengths of 5m, 10m and 15m, must be interconnected in a
ring configuration between the UPS modules, as shown in Figure 7-2.
Method: connect a module parallel cable from its PARA1 port to the PARA2 port of another module, repeat for all the
other parallel cables.
The ring connection ensures the reliability of the parallel system control circuit. Be sure to verify the parallel cables
have been connected correctly before starting up the system!

8.1.10

LBS Cables

The shielded and double-insulated parallel cables are available in lengths OF 5m, 10m and 15m. Connect the two
optional LBS cables in a ring configuration: from the LBS1 port of one UPS module to LBS2 port of another UPS
module, and from the LBS2 port of one UPS module to LBS1 port of another UPS module, as shown in Figure 7-6 and
Figure 7-7.
