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”
.

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

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
