Potential Free Contact - Miele DSM 400 Operation & Installation

Potential free contact.

(connection must be made a suitably
qualified electrician only)
^ Before connecting to an additional
light switch the lid of the control
module has to be taken off. It is
refitted later.
Potential free contact can be made
using terminal c on the control module.
This enables another appliance to be
controlled according to the switch
setting on the cooker hood fan.
If a window contact switch has not
been connected to the control module,
terminal a will have to be bridged.
Electrical connection
Because contact c supplies no
defined voltage (it is potential free) it
can be used anywhere.
In the illustration shown the potential
free contact is used to switch on an air
intake fan as soon as the cooker hood
is switched on, and thus ensure an
adequate supply of fresh air into the
room.
All connected components must be
tested for safety after they have
been connected.
