Installation Altitude and Ambient Temperature
Nominal data
The motor performance data specified are applicable for
●
Ambient temperatures from 0° ...+40°C
●
Installation altitude of 0 ... 1,000 m above sea level.
Exceeding the nominal data
MKE motors are certified by the regulation office for the temperature range
0° ... +40° C. Any deviations repeal the certification. Please contact your re‐
sponsible sales office, if you use the motors outside the specified area of use.
They can give you some recommendations for special certifications.
9.3
Degree of Protection
The degree of protection is specified by the IP-Code. The code consists of
the abbreviation IP and two characteristic numbers describing the degree of
protection.
The first digit defines the degree of protection against contact and penetra‐
tion of foreign particles. The second digit defines the degree of protection
against water.
1st digit
Degree of protection
6
Protection against penetration of dust (dust-proof);
complete contact protection
2nd digit
Degree of protection
5
Protection against a water jet from a nozzle directed against the
housing from all directions (jet water)
Fig.9-5:
IP types of protection
The second characteristic number defines the degree of protection
against water. If cleaning is effected using high pressure and/or solvents,
coolants, or penetrating oils, it might be necessary to select a higher degree
of protection.

Compatibility with Foreign Materials
All Rexroth controls and drives are developed and tested according to the
state of the art.
However, since it is impossible to follow the continuing further development
of every material with which our controls and drives could come into contact
(e.g. lubricants on tool machines), reactions with the materials that we use
cannot be ruled out in every case.
For this reason, you must execute a compatibility test between new lubri‐
cants, cleansers, etc. and our housings and device materials before using
these products.
