ENGLISH
Use only suitable and high-class connection parts and seals to connect the machine to the water circuit.
In environments with a risk of sub-zero temperatures, a glycol/water mixture can be used with a 40/60 mixture
(glycol/water), with a recommended minimum environment temperature of -20°C.
The lower the cooling water input temperature, the better the cooling of the motor.
For some cases, a higher input temperature can be allowed when requested and checked by the manufacturer.
Theoutlet water temperature rise is 2–10K.
The minimum pressure and amount of cooling water for the basic construction of a water cooled motor is shown in
Table 5 Water pressure and flow rate. Please check the requirements for pressure and the amount of cooling water in
the case of special constructions.
(If the amount of water varies, its temperature rise will be inversely proportional to the flow rate.)

1.5.2.2 Air cooling (M3ET, M3FT )
WARNING:
All the IP23 motors (M3FT) have a forced-air cooling system which uses radial blowers. Air is blown inside the motor
and cools the frame and the active parts.
WARNING:
WARNING:
IP55 air cooled motors (M3ET) frame size 250 and above have a forced-air cooling system which uses radial blowers.
IP55 air cooled motors (M3ET) from frame size 80 up to 225 use an axial fan mounted on the NE side.
Air is moved by a component mounted on the motor, the power for which is obtained in such a way that it is
independent of the rotational speed of the machine.

DO NOT USE ANY COOLANT OTHER THAN AIR!
For IP23 M3FT 200-400 and M3ET 250-355, never connect a 50Hz fan unit with 60Hz
supply! This can lead to the production of severe damage to the fan and to the fan
motor.
For IP23 M3FT 200-400 and M3ET 250-355, never connect a 60Hz fan unit with 50Hz
supply! This can lead to the overheating of the HDP motor, due to the reduced air-
flow.
