Cable connections
There are 2 types of cable connections:
•
APM UPS to APM UPS
•
APM UPS to non-APM UPS
APM UPS to APM UPS
To connect an APM UPS to another APM UPS, proceed as follows:
1.
Connect the LBS adapter power cables to the Phase A, neutral, and ground output of each UPS.
2.
Connect the end of the LBS cable with a DB9 port to the COM1 port on the LBS adapter.
3.
Connect the other end of the LBS cable, with an RJ45 port, to the J19 port on the UPS bypass module.
4.
Connect the communication cables (up to 150m) to the COM2 port on each LBS adapter.
5.
Set the switch on both the LBS adapters to the right position.
Figure 9-8 illustrates the connections between the two LBS adapters:

APM UPS to non-APM UPS
To connect an APM UPS to another UPS (any UPS other than an APM UPS), proceed as follows:
1.
Connect the LBS adapter power cables to the phase A, neutral, and ground output of each UPS.
2.
Connect the end of the LBS cable with a DB9 port to COM1 port on the LBS adapter, and connect the other
end of the LBS cable, with a RJ45 port, to the J19 port on the bypass module of the APM UPS. Do not
connect anything to the COM1 port on the LBS adapter connected to the non-APM UPS.
3.
Connect the communication cable (up to 150m) to the COM2 port on each LBS adapter.
4.
Set the switch on the LBS adapter connected to the APM UPS to the right position
5.
Set the switch on the LBS adapter connected to the non-APM UPS to the left position.
The circuit diagram in Figure 9-9 illustrates the connection between the 2 LBS adapters in the case of an APM
UPS and non-APM UPS.

LBS Cable
The LBS cables are shielded and double-insulated parallel controlled cables available in a variety of lengths (10m,
15m, and 20m). The LBS cables must be interconnected in a ring configuration between LBS 1 and LBS 2 of the
UPS modules, as explained in Chapter 8, which covers the LBS systems.
9.1.8
Parallel Cable
The shielded, 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. To do this, connect a parallel cable
between the PARA1 port of the first module to the PARA2 port of the next module and continue in this way until
all the modules have been connected and the ring has been formed by connecting the PARA1 port of the last
module to the PARA 2 port of the first. Connecting the modules in a ring configuration ensures the reliability of
the control of the parallel system. Make sure that all the cables have been connected securely before starting the
system!
