7.3 Fan Unit
» Connect fan unit as specified in the wiring diagram.
The fan unit is activated/deactivated in parallel with humidifica-
tion.
Note: Terminals 37 und 38 are supplied with the unit only when
the fan unit and humidifier are purchased simultaneously. In
other cases (i.e. retrofitting) the fan unit motor phase can be
connected to Terminal 2 guided via the auxiliary contact of the
main contactor.
Only cables with same diameter are alllowed to be connected to
one common clamp.
7.4
Safety Interlock
Note: Install contact interlocks, i.e. max. hygrostat, vane relay,
pressure controller, air interlock etc. in series between Terminals
1 and 2.
Warning: It is standard practice to install a max. hygrostat in the
safety interlock. The max. hygrostat acts as a safety device in
the event of a humidity sensor malfunction and protects against
overhumidification.
