SALICRU
The UPS accepts an external signal from relays connected
through the relay interface and Phoenix terminals. Through
software programming, these signals are activated when these
contacts are connected to +24 V to earth. The cables connected
to the DRY terminal must be separated from the power
cables. In addition, these cables must have double insulation
with a typical cross section of 0.5 to 1.5 mm
2
for a maximum
connection length between 25 and 50 metres.
5.3.4.1. Relay interface.
The relay interface includes ports J2-J10
(1)
. The functions of
the relay interface ports are shown in Tab. 7.

Make sure that the rectifier and bypass input cables
have no voltage when connected.

Tab. 7. Functions of the relay interface ports.
The adjustable functions for each port can be modified
from the control software.
The default functions of each port are described as follows:
Output relay interface for ambient temperature detection
Ports J2 and J3 can detect, respectively, the temperature of the
batteries and the environment, and be used to monitor the envi-
ronment and compensate for the temperature of the batteries.
The diagram of ports J2 and J3 is shown in Fig. 41 and the
description in Tab. 7.

Tab. 8. Description of J2 and J3.
A specific temperature sensor is required for
temperature detection (R25 = 5 kOhm, B25/50 = 3275):
check with the manufacturer or contact the maintenance
engineers when ordering.
Relay interface for remote EPO
J4 is the input port for remote EPO. During normal operation,
24 V with NC and open the jumper between NO and
+24 V.
The EPO trips when opening the jumper between NC and +24 V
or when jumpering NO and +24 V (J4-3). The diagram of the port
is shown in Fig. 42 and the description in Tab. 7.
