5.1.1 Diesel generator
The Diesel Mode function can be enabled via the Test Software. The UPS is already
provided with the internal wiring as well as with terminals XD1-XD2 to be connected to
the Generator. The diesel generator interface provides to limit the rectifier output
voltage in order not to recharge the batteries during the Gen Set operation. In this way
the rectifier needs a lower current to feed the DC loads (inverter) and a considerable
amount of energy is saved, therefore the rating of the generator power can be lower.
A contact indicating the Gen Set operation must be connected to two terminals XD1
XD2 already provided on the UPS terminal board.

5.1.2 Off-line
The OFF-LINE function can be enabled in the “single configuration” via the Test
Software. The load will be supplied by the electronic bypass until the bypass is present
and within tolerance. In the event of a bypass line failure, the load is transferred to the
inverter without interruption.
