Connection
Voltage supply for the 8279 plug-in module:
- Plug the module on the controller.
- Bridge terminals 7 and 39.
Note:
With this type of wiring there are 2 or more wires connected to
one terminal. To avoid this, provide an external connection facility.

Danger!
There is no mains isolation between external supply and unit
mass.
There is no double mains isolation between the mains and the
terminals.
Therefore, the unit is not electrically isolated, i.e. not protected
against contact.
