7.2 Supply voltage
► Connect the supply voltage of the device to terminals L+ and L-.
For safety reasons the unit can only be restarted by separation from the voltage
supply in case of a fault.
It is thus recommended to install a RESET button in series with the L+ circuit.

The external supply unit must have a safe separation. In case of a fault the
supply voltage can exceed the value of 60 V DC for a maximum of 200 ms,
but must not exceed the value of 120 V DC.
After power on or a RESET the device carries out self diagnostic functions.
This self diagnosis lasts approx. 6 seconds. The unit is then ready for
operation.
7.3 Switch point setting
► Set the requested switch point via a hard-wired bridge on the terminals S33,
S44, Y2 or Y6.
Only change the switch point when disconnected from power.
When switched on, a change of the circuitry will produce an error message
of the device.
