- Utility Failure
(def. Param. RL=1)
J2/4, 5, 6 - NO, C, NC - Load on Inverter (def. Param. RL=3)
J2/7, 8, 9 - NO, C, NC - Stop Operation (def. Param. RL=5)
J2/14, 15, 16 - NO, C, NC - Load on Utility (def. Param. RL=2)
J2/17, 18, 19 - NO, C, NC - General Alarm (def. Param. RL=4)
J2/20, 21, 22
- NO, C, NC
- Acoustic Alarm (def. Param. RL=6)
Signals on terminals X1 and on connector J2 are in parallel
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”.

Note: to enable this function, remove cable short-circuiting XB / 2 – 3 and
the Jumper JP3 on P4 – 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).

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
14- Rectifier Utility Failure
15- Battery Discharge

Some UPS functions can be activated with
parameters when an external Normally Open
contact is closed on:
X1-10, 21 / J2-10, 23 or X1-11, 22 / J2- 11, 24
Selectable functions by changing parameters
(password required) are:
0 - No function 1 - Inverter ON
2 - Inverter OFF 3 - Print All
4 - Status Relay 5 - Generator ON
6 - External Bypass ON
7 - External Battery Fuses, or External K3.
See Alarm 4104 - “Battery Fuses”.
