Note
Open input
An open input is interpreted as "low".
Note
If terminals 3 ... 6 are not used, then you must connect 24 V DC to these.
To do this, use an external power supply or terminal 9 on the Control Unit.
The reference potential is connected to terminal X9:2, 7, and terminal 28 on the Control Unit.
WARNING
Danger to life as a result of a hazardous voltage at the 0 V to 48 V DC terminals
In the event of a fault, touching live parts can result in death or severe injury.
• Only connect protective extra-low voltages (SELV/PELV) to all connections and
terminals between 0 to 48 V DC.
Note
Line contactor control
When supplying the main contactor via terminals 11 and 12, separation from the line supply
using a control transformer is not required. A 250 V/8 A fuse in compliance with UL must be
used as protection.
