Fig. 38. Connection of the communication BUS.
• Together with each UPS of a parallel system, it is supplied a 15
wires bundle with HDB15 connectors at both ends, one male
and the other one female, with a length of 5 m. Therefore, there
will be as many communication BUS bundles (BC), as quantity
of equipments to parallel have the system.
5.2.10.1. Connection of the communication or BUS bundle (BC).
• Respect the sequence and connection order of the communica-
tion BUS among correlative equipments.
Although the order of the connections of communication BUS
among equipments are made, is not important, on condition
that the communication loop is completed or closed properly, it
is advisable to carry out the connections with the immediately
next equipments in order simplify the connection.
• The connection limit of the installation, will be determined by
the quantity of available equipments to parallel and in any case
till a maximum of four units.
• Each equipment has two HDB15 connectors for the communi-
cations among them, one male labelled as "Output" (X36
another one female as "Input" (X36
• In the same way, all the bundles supplied with the equipments,
are equal in connections and length.
DO NOT MODIFY THE COMMUNICATION BUS
BUNDLE, OR THE CONNECTORS UNDER ANY
CONCEPT.
• Take one of the bundles and insert the HDB15 female connector
located in one of its ends, into the male connector labelled as
"Output" (X36 ), in any of the equipments of the system and
o
insert the HDB15 male connector located in the opposite end of
the bundle into the female connector labelled as "Input" (X36
of the adjoining equipment.
• Repeat the previous step with each equipment of the system,
till closing the communication BUS loop or ring.

• As an example, Fig. 38 shows, how the communication BUS
connections have to be done.
Although this illustration is not representative for the complete
SLC CUBE3+ series, as for the format of the cabinet, terminal
layout or size and/or switches, as well as the own communica-
tion ports, it expects to be a guide to clarify the possible doubts
on how the communication loop has to be connected.
To see the physical layout of the COM connectors for each
power rate, refer to the illustrations of figures 6 to 14.
• The base of front door (PF) has a slot to facilitate the entering and
way out of the communication cables inside the UPS. Watch to not
trap them between the door and cabinet when closing it.
