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

Status relay
Voltage free contacts:
Max. DC / AC: 24V / 1.25A
IEC 950 (SELV circuit)
Min. signal level: 5VDC / 50mA
Gen Set signaling
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.
4.4-1 / X1 and J2
).
When this contact closes, it causes the change of certain settable functions such as:
•
Enabling or disabling of synchronization 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.
