Connection of several units
If necessary, several units (also dif-
ferent sizes) can be operated paral-
lel via a control unit (accessory).
The total capacity of the con-
nected units must not exceed the
maximum switching capacity of
the respective control unit.
For thermal motor protection, the
thermal contacts of all motors
must be connected in series. See
separate wiring diagrams.
Only one external control device
(thermostat, day/night control,
etc.) can be connected per control
unit.
terminal box on unit
Fuse protection in the supply
to the control unit must be in
compliance with the applicable
regulations.
The connections in the terminal
box must be connected to the
respective control unit (accessory).
Electrical connections of the unit
must only be established by au-
thorised specialists in compliance
with the applicable regulations of
the local electricity supply compa-
ny as well as the VDE installation
requirements relating to the unit.
Unit connection
The units are fitted with two-
speed, 400V three-phase axial fans
as standard.
With the appropriate control units
(accessory), speed selection takes
place via Y/D switching.
Motor protection is provided
via built-in thermal contacts
that drop out at a fan motor
winding temperature of 130°C in
conjunction with a suitable control
unit (accessory).
Connection of the three-phase
motors to the respective control
units takes place via the associated
electrical wiring diagrams.
