Enclosure
General Information
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
Enclosure
Protection against accidental contact
and penetration of foreign bodies
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
