G1.2 - SPACE HEATERS
Severe climatic conditions may require the
use of space heaters (fitted to the motor
windings) which serve to maintain the
average temperature of the motor, provide
trouble-free starting, and eliminate problems
caused by condensation (loss of insulation).

No. of
poles
The space heaters use 220/240V, single phase, 50 or 60 Hz.
G1 - Electrical options
The heater supply wires are brought out to a
domino or terminal block in the motor
terminal box. The heaters must be switched
off while the motor is running. They must
only be switched on when the motor is cold
and stationary.

G2 - Mechanical options - Non-standard flanges
Optionally, LEROY-SOMER motors can be
fitted with flanges and faceplates that are
larger or smaller than standard. This means
that motors can be adapted to all types of
situation without the need for costly and
time-consuming modifications.
