The external connection ports shown in the previous figures are
described below:
•
RS-232/USB
: for connection to proprietary programming
and control software.
•
SRC-2 (optional)
: relay card used for remote signalling of
states and alarms.
•
Parallel (optional)
: used for parallel UPS communication.
•
MODBUS (optional)
: used for the transmission of data to
the outside through the MODBUS RTU protocol (RS-485).
•
Thermal probe (optional)
: used to measure the
temperature of the cabinet/battery room and adjust the
charging voltage automatically.
•
SNMP (optional)
: used for the external transmission of
data through a LAN.
•
Normal/Bypass selector
.
5.2.5. Relay interface connection.
The SLC X-PERT UPS, in its complete configuration, is equipped
with a 5-relay interface in order to transmit alarms and operating
states remotely. The electrical connection is made directly to
the terminals located on the front of the SRC-2 interface slot.
