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 / Generator ON (NO) (def. = RL2)
NO
= Normally Open
C
= Common
NC
= Normally Closed
The connectors
J4
and
J5
can be used for additional
3-ph SNMP/WEB plug-in adapter
or an additional
Customer
Interface
(installation only when the UPS is switched Off).
XA
: terminals for 24Vdc Auxiliary Power Supply connection.
XB
: terminals for
EPO
connection.
Programmable user relays
Programmable functions on contacts (X1 - J2)
On terminals
X1
or
J2
connector, six of the following
26
signals
can be selected from the display, entering with
the appropriate password.
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”
