Output signals on voltage-free contacts
On terminals X1 or J2 connector 6 of the following 28 signals can be selected from the display
(access only with password): SETUP / SETUP / LEVEL 2: SERVICE.
0 - No signal 15 -
Programmable functions on input contacts (X1 - J2)
Some UPS functions can be activated by parameters (access with password only) when an external
NO contact is closed on:
No function Inverter On
Inverter OFF Generator ON
Print all Status relay
External bypass ON External battery fuses
Voltage free contacts:
Max. DC / AC: 24V / 1.25A
IEC 60950 (SELV circuit)
Min. signal level: 5Vdc / 5mA
Gen Set signalling
If an Emergency generator set supplies the UPS in case of utility failure and the generator is particularly
unstable in frequency, it should be suitable to install the signal “generator on” on terminals X1 / 11, 22
(Normally Open voltage-free contact) or on connector J2 / 11, 24 (see Fig. 10.2.1-1 / X1 and J2).
Since the Parameter for of the reading of the Generator function is password protected, call the nearest
Service Centre for it's activation.
When this contact closes, it causes the change of certain settable functions such as:
• Enabling or disabling of synchronisation and consequently the load transfer to generator.
• The battery recharge inhibition during the generator operation, or after what delay from generator
start the battery will start to be recharged.
Consult your nearest Service Centre for more information.
In a Parallel System a separate NO (Normally Open) contact must be connected to
each individual unit.
