Terminal assignment
Terminals Designation Function
REMOTE OFF If the terminals are short circuited by a normally
open contact (R < 1 kΩ), for instance, the power
supply unit is switched off remotely.
If the resistance R between the terminals is
> 10 kΩ, the power supply unit is switched on.
Attention:
Terminal potential = Input voltage
INPUT OK

Potential-free change-over contact
11-14 closed and 11-12 opened, when the power
supply unit input voltage is > 85 V AC / 90 V DC.
11-12 closed and 11-14 opened, when the power
supply unit input voltage is 82 V AC / 70 V DC.
11-14 also closed with REMOTE OFF.
OUTPUT OK
