3.3.5 Permissible ambient temperature range
For all motors, the permissible ambient temperature range is -20°C...+40°C. For IE1/IE2 motors for
operation in Zones 21 and 22, an extended ambient temperature range from -20°C...+ 60 °C is
permissible. In this case, the rated power must be reduced to 72 % of the value stated in the catalogue.
If the maximum ambient temperature is b40°C and + 60 °C, the power output should be inversely
linearly interpolated between 100 % and 72 %. Thermal motor protection by PTC resistor temperature
sensors is mandatory. The motor connection cables and the cable glands must be suitable for
temperatures of at least 80°C.
The extended ambient temperature range does not apply for optional attachments such as a brake, an
encoder and/or an external fan. Contact the manufacturer in case of doubt with regard to permissibility!

3.3.6 Painting
The motors are equipped with a suitable, electrostatically tested painting ex-works. Subsequent painting
may only be carried out in consultation with Getriebebau NORD or a repair workshop approved for the
repair of explosion-protected electric motors. The valid standards and regulations must be observed.

3.3.7 IEC-B14 motors
Please comply with the information in Section 1.3.2. Otherwise, explosion protection is not ensured.

3.3.8 Motor position – special features IM V3, IM V6
If the end of the shaft faces upwards, e.g. version IM V3, IM V6, a cover must be provided by the
operator / installer, which prevents foreign bodies from falling into the fan cover of the motor (see
EN IEC 60079-0:2018). This must not obstruct the fan from cooling the motor. If the end of the shaft
faces downwards (AS, inclination 20° to 90°), e.g. versions IM V1, IM V5, the motors are to be used with
a protective cover on the fan cover. For an inclination of less than 20°, an appropriate protective device,
which meets the above mentioned conditions, must be provided by the operator / installer.
A hand wheel on the second shaft end is not permitted.
