Description
(230V 50 Hz; 400-415V 50 Hz and 440V 60 Hz)
The motor is mounted under the drum and drives the drum directly on its output shaft. To
reduce motor noise and vibration the entire drum unit has rubber dampers. On flexibly-
mounted models this damping is provided by either eight or ten rubber straps, while the
drum models this of R- models is mounted on two relatively rigid rubber bushings.
Electrical connection is to block X1 in the control unit.
The extractor connection is to block X1 in the control unit.
The extractors are prepared for switching between star connection (400 - 415V) and
delta connection (230V). Switchover is performed by changing a cable set between relay
and motor. For 440V 60 Hz, cable set A is used.
Cable set A = star connection
When switching over the auxiliary transformer the strap on the transformer connection
block should be moved to the desired voltage.
Please note!
When the extractor connection type is being switched over,
the auxilliary transformer must also be switched accordingly.
