Enclosure
Installation
The motors can be installed outdoors and in dusty and chemically aggressive environment (industrial climate) at ambient temperature from -20 to +40°C.
Mechanical protection
The mechanical protection systems for electric motors are classified with the IP code followed by 2 numbers and (in some cases) by a letter.
IP (International protection)
1st digit: 0-6
It stands for the kind of protection against accidental contacts of foreign bodies.
2nd digit: 0-8
It stands for the kind of protection against water

Protection against accidental contact
|
Protection against water |
IP23: Standard design for series AB, KA-A, AHV |
Protected against solid objects over 12mm (e.g. fingers) |
Protected against rain water at an inclination up to 60° |
IP54 | Complete protection to prevent contact with live parts and approaching live parts as well as contact with moving parts inside the enclosure. Protection against harmful dust deposits. No complete protection against dust, but sufficiently protected to maintain satisfactory operation of the machine |
Motor will not be damaged by splashing water |
IP55: Standard design for series K, AK, MK KHV, TMKHV |
A jet of water from a nozzle, pointed at the motors from any direction, will not damage the motor |
|
IP56: (option for K, AK, MK, KHV, TMKHV) |
Protection is sufficient to prevent a damaging amount of water from entering the enclosure if the motor is exposed to heavy sea movement or if a concentrated jet of water is directed at the motor |
|
IP65 (option for K, AK, MK) Acc. DIN 40 050/ July 1980 (first ID no [6] dustproof, not contained in DIN IEC 34 Pt 5) |
Complete protection to prevent contact with live parts and approaching live parts as well as contact with moving parts inside the enclosure. Sealed to prevent ingress of dust (dust proof) |
A jet of water from a nozzle, pointed at the motors from any direction, will not damage the motor |
