DO NOT attempt to operate the actuator with the
brake applied. Allowing the actuator to operate
with the brake applied may cause serious damage
to the actuator and/or the brake. Do not use the brake to
support heavy loads while an operator is under the load.
Provide another means to lock the load in position. The
brake is a spring applied friction mechanism and does not
provide a positive lock.
2.8 Ingress Protection Rating
The standard IP rating for GSM Series actuators is IP54S with an
option for IP65S. Ingress protection is divided into two categories; solids
and liquids. For example, in IP65 the three digits following
“IP” represent
different forms of environmental influence:
• The first digit represents protection against ingress of solid objects.
• The second digit represents protection against ingress of liquids.
• The suffix digit represents conditions of motion during the operation.
Digit 1 - Ingress of Solid Objects
The IP rating system provides for 6 levels of protection against solids.
1
Protected against solid objects over 50mm e.g. hands,
large tools.
2
Protected against solid objects over 12.5mm e.g. hands,
large tools.
3
Protected against solid objects over 2.5mm e.g. wire,
small tools.
4 Protected against solid objects over 1.0mm e.g. wires.
5
Limited protection against dust ingress.
6 Totally protected against dust ingress.
Digit 2 - Ingress of Liquids
The IP rating system provides for 9 levels of protection against liquids.
1
Protected against vertically falling drops of water or
condensation.
2
Protected against falling drops of water, if the case is
disposed up to 15 degrees from vertical.
3
Protected against sprays of water from any direction, even if
the case is disposed up to 60 degrees from vertical.
4 Protected against splash water from any direction.
5
Protected against low pressure water jets from any
direction. Limited ingress permitted.
