4.1 CUSTOMER INTERFACE
J3 - Serial port RS 232 (sub D - female 9 pin)
Suitable for GE protocol
Pin 2: TX (out) Pin 3: RX (in) Pin 5: GND
J2 - (subD-female 25 pin) – Output signals on voltage free contacts
J2/1, 2, 3 NO, C, NC Utility Failure (default Parameter RL=1)
J2/4, 5, 6 NO, C, NC Load on Inverter (default Parameter RL=3)
J2/7, 8, 9 NO, C, NC Stop Operation (default Parameter RL=5)
J2/14, 15, 16 NO, C, NC Load on Utility (default Parameter RL=2)
J2/17, 18, 19 NO, C, NC General Alarm (default Parameter RL=4)
J2/20, 21, 22 NO, C, NC Acoustic Alarm (default Parameter 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”.
Terminals for EPO connection (for XB terminals see Section 4.1.6)
XB/1, 4 or J2/12, 25 NC EPO (Emergency Power Off) - See Section 4.7.1
Note: to enable this function, remove cable short-circuiting XB / 2 – 3 (see
Section 4.1.6) and the Jumper JP3 on P4 – Customer Interface.
X1 – Output signals on voltage free contacts - terminals
X1/1, 2, 3 NO, C, NC Utility Failure (default Parameter RL=1)
X1/4, 5, 6 NO, C, NC Load on Inverter (default Parameter RL=3)
X1/7, 8, 9 NO, C, NC Stop Operation (default Parameter RL=5)
X1/12, 13, 14 NO, C, NC Load on Utility (default Parameter RL=2)
X1/15, 16, 17 NO, C, NC General Alarm (default Parameter RL=4)
X1/18, 19, 20 NO, C, NC Acoustic Alarm (default Parameter RL=6)
Input contacts
X1/10, 21 or J2/10, 23 Programmable (default = RL1)
X1/11, 22 or J2/11, 24 Programmable / Generator ON (NO) (def. = RL2)

NO = Normally Open C = Common NC = Normally Closed
J5: This connector can be used for additional 3-ph SNMP/WEB plug-in adapter (installation only when the UPS is
switched Off).
P27 - IM0108: Interface to External Bypass (see Section 3.9.5 and 3.9.6).
XA: terminals for 24Vdc connection (see Section 4.1.5). XB: terminals for EPO connection (see Section 4.1.6).
Programmable user relays Programmable functions on contacts (X1 - J2)
On terminals X1 or J2 connector, six of the following 27
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 syncron.
12- Bypass Locked
13- Bypass Utility Failure 14- Rectifier Utility Failure
15- Battery Discharge
16- Manual Bypass ON
17- Rectifier ON
18- Inverter ON
19- Boost Charge
20- Battery Earth Fault
21- Battery Fault
22- Relay Input 1
23- Relay Input 2
24- Relay Output ON
25- Relay Output OFF
26- EPO (Emergency Power Off)
27- eBoost/IEMi mode
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”
8 – eBoost/IEMi control
