The communications line -COM- constitutes a very
low voltage safety circuit. To maintain quality, it
must be installed separately from other lines that carry
dangerous voltages (power distribution line).
The RS232 interface is useful for firmware updating, while
the USB is useful for monitoring software.
It is not possible to use both RS232 and USB ports at the
same time.
The TX and RX signals of the RS-232 protocol are supplied
in the DB9 connector.
The RS232 port consists of serial data transmission, so
that a large amount of information can be sent through a
communication cable with only 3 wires.
USB communication port supports USB 1.1 protocol for
communication software.

To parallel equipment, it is necessary to interconnect both
ports (output of one, input of the next using the supplied
cables).

expansion card for communications, signaling and/or other
services. By default, the "Nimbus" communications card is
supplied, which allows connection to SALICRU's proprietary
"cloud" services.
4.6.3.2. Manual bypass auxiliary contact terminals
(EMBS).
The unit's manual bypass switch
hind its mechanical lock. This normally open contact is extended to
a two-terminal strip (EMBS) located behind the unit (see Fig. 19
and Fig. 24) and internally connected to the UPS control.
On distribution boards with a manual bypass supplied on request,
there is a two-terminal strip connected in parallel with the normally
open auxiliary contact of the manual bypass switch or disconnect
switch of the board itself. The manual bypass auxiliary contacts
are of the advanced when closing type.
The connection between the board's auxiliary contact and the UPS
or UPSs is in parallel with that of the board. As such, any of the
auxiliary contacts that close the circuit will activate the inverter stop
order, supplying output voltage via the static bypass, unless it is
disabled via the control panel, which will cut the power to the loads.
In parallel systems, the manual bypass switch or discon-
nect switch of the distribution board has an auxiliary con-
tact block for each unit. Under no circumstances join the different
contacts to each other, thus avoiding joining the different earths of
the control of each UPS.
If you acquire a manual bypass panel from another source,
check that it has the indicated auxiliary contact and con-
nect it to the terminal strip of the UPS or of each unit in parallel
systems. The auxiliary contacts must be the advanced when
closing type.
As a safety measure for the system, including the loads, it
is ESSENTIAL to connect the UPS strips to the strip with
the same functionality on the manual bypass panel. As such, an
incorrect action on any manual bypass switch or disconnect switch
with the UPS running will be prevented from causing the total or
partial failure of the installation, including loads.
