1.2 Field of use
Use of the motors:
The motors may only be used for their intended purpose (to drive machinery).
The motors are constructed with at least protection class IP55 (for the protection class: see rating plate).
They may be installed in dusty or damp environments.
In principle the conditions of use and the ambient conditions determine the necessary protection class
and any other additional measures. For outdoor installation and vertical versions, e.g. V1 or V5 with the
shaft pointing downwards, Getriebebau NORD recommends the use of the double fan cover option
[RDD].
Motors must be protected against intensive sunlight, e.g. by the use of a protective cover. The insulation
is tropicalised.
Installation altitude: ≤ 1000 m
Ambient temperature: -20°C...+40°C
For standard motors an extended ambient temperature range from -20°C... +60 °C is permissible.. In this
case, the rated power must be reduced to 82 % of the value stated in the catalogue. If the maximum
ambient temperature is b 40 °C and + 60 °C, the power output should be inversely linearly
interpolated between 100 % and 82 %.
T he motor connection cables and the cable glands must be suitable for temperatures ≥ 90°C.
