Fig. 4.1-1 Customer interface
The connectors J4 and J5 can be used for additional SNMP Card , Environmental Card (not available yet)
or an additional Customer Interface (installation only when the UPS is switched Off).
XA : terminals for 24VDC Auxiliary Power Supply connection.
Programmable user relays
On terminals X1 or J2 connector, six of the following 26
signals can be selected from the display, entering with the
appropriate password .
0- No Information
1- Buzzer
2- General Alarm
3- Load on Utility
4- Stop Operation
5- Load on Inverter
6- Utility Failure
7- DC Over Voltage
8- Low Battery
9- Overload
10- Over Temperature
11- Inverter-Utility not syncr.
12- Bypass Locked
13- Bypass Utility Failure

and therefore not separated galvanically from each other.
The programmable signals on X1 and J2 will be disabled with Q1
open, with the exception of the signals for "16 - Manual Bypass ON"
and "26 - EPO".

C = common
XB : terminals for EPO connection.
Programmable functions on contacts (X1 - J2)
Some UPS functions can be activated with
parameters when an external Normally Open
contact is closed on:
X1-10, 21 / J2-10, 23
Selectable functions by changing parameters
(password required) are:
0 - No function
2 - Inverter OFF
4 - Status Relay
6 - External Bypass ON
7 - External Battery Fuses, or External K3.
See Alarm 4104 - "Battery Fuses".
