Connection scheme and fan motor absorption
( * ) Inner protection thermal contacts
The thermal contacts are temperature sensing, switching ele-
ments built directly into the windings of the motors. They interrupt
an electrical contact when maximum admissable sustained tem-
perature has been reached.
The thermal contacts must be connected to the control circuit of
the mains contactor to prevent automatic reconnection of the
motor in the event of a fault.

Caution
Application of adequate thermal control systems on feeder lines is mandatory.
Performance of all electric heaters must be periodically controlled to avoid damage due to ice build-up.
The manufacturer is not liable in any way for defects caused by non detected malfunctions.

Caution
To avoid possible motor damage strictly follow the electric sche-
mes shown.
Before using motor speed control systems verify the compatibility
with the motors; non compatible systems may damage motors or
increase noise level; the manufacturer will not be responsible for
model performance with speed control systems.
