8.1.4
Derating factors
Given an ambient temperature > 40 °C or installation altitude > 1000 m above sea level, the
permissible torques/powers must be determined with the factors from the following table.
The factors refer to the static torque M
0
. Shift the S1 characteristic curve in parallel.

Calculate the derating value for ambient temperatures that are not shown here and installation altitudes
below the maximum values by interpolating. For example: 40 °C at 1500 m above sea level = derating
factor 0.975
8.1.5
Degree of protection
The degree of protection designation in accordance with EN 60034-5 (IEC 60034-5) is
described using the letters IP and two digits (e.g. IP64).
IP = International Protection
1st digit = protection against the ingress of foreign bodies
2nd digit = protection against water
DIN 60034-5 is valid for water as potentially occurring medium, not for oil or other creeping
fluids.
Configure the motor in the required degree of protection.
Degrees of protection available for the 1FK2
The 1FK2 motors are available with the following degrees of protection:
● IP64
● IP65 optional
The motors with IP65 degree of protection have a radial shaft seal.
