2.3.1 SITOP UPS1600
2.3.1.1 Rotary coding switch, switch-in threshold
The switch-in threshold can be set using the rotary coding switch ⑦ on the device front
between 21.0 V and 25.0 V (21 - 21.5 - 22 - 22.5 - 23 - 24 - 25 volt). The delivery state is
21.5 V
For devices with an interface (…-1AY0, …-2AY0), the coding switch has an additional position
REN. If this is selected, the software settings (for the switch-in threshold and the backup
time) apply rather than the hardware settings. In the switch position REN, connection X2.13
(INTERRUPT - reset after buffer mode) of the signal terminal (see Chapter Signal terminal
(Page 28)) has no effect.

Note
It is only permissible to operate the rotary coding switch using an insulated screwdriver.
The stop buffering voltage is a voltage to be set, which must not be fallen below in the case
of a buffering event. This ensures that the undervoltage monitoring of the device supplied
from the UPS does not trip as a result of the decreasing output voltage during the buffering
event. Customers can set the voltage.
For notes on actuating the rotary coding switch (screwdriver, torque), see Figure 2-5
