Outdoor operation
ZB motors are supplied with IP 54 as standard. For brake sizes B003 - B680, IP 54
dust protection only applies for non-magnetic and non-magnetisable particles in
this case. All motors are available with IP 55 and IP 65 enclosure, on request,
which then also provides protection against magnetic or megnetizable particles.
Brief explanation of enclosures:
Protection against harmful dust accumulation, protection against splashwater from
all directions.
Protection against harmful dust accumulation, protection against hose-water from
all directions.
Detailed descriptions of these enclosures and test methods can be found in
EN 60034 part 5 (DIN VDE 0530, part 5).
Complete protection against dust accumulation, protection against hose-water
from all directions.
Detailed descriptions of these enclosures and test methods can be found in
EN 60529.
If a motor is operated under arduous conditions outdoors, e.g. unprotected
installation in wind and rain or installation at great heights, standard IP 54
enclosure may not be sufficient.
In these cases the motor must be provided with IP 55/IP 65 enclosure or protected
by suitable measures, e.g. wind and rain deflector. For vertically mounted motors
with the shaft facing downwards, a canopy/round protection panel is available at
an extra price.
