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
22.5 V
For devices with an interface (…-1AY0, …-2AY0), the coding switch has an additional
position (REN, see the following figure). 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, the connection X2.13 (INTERRUPT - reset after buffer operation) of the
signal terminal (see Section Signal terminal (Page 16)) has no effect.

Note
It is only permissible to actuate the rotary coding switch using an insulated screwdriver.
For notes on actuating the rotary coding switch (screwdriver, torque), see Figure 2-3
UPS1600 terminal data (Page 15).
