5.1 Safety
DANGER
H
azard due to unexpected starting of the machine
Death or severe injury
b
Make sure that the dangerous state of the machine is and remains switched off.
DANGER
B
ypassing the protective device
Hazard due to lack of effectiveness of the protective device
b
Prevent incentives to manipulate the safety switch by taking at least one of the fol‐
lowing measures:
°
Universally coded variant only: Attach safety switches with a cover or with
shielding, or ensure they are out of reach.
°
If possible, use non-detachable mounting methods for actuators (such as
welding, gluing, non-removable screws, or rivets).
NOTICE
Incorrect mounting and unsuitable ambient conditions may damage the safety switch.
b
Arrange the sensor and actuator in a way that prevents damage from foreseeable
external influences.
b
Do not use the sensor and actuator as a stop.
b
The holder and mounting method for the sensor and actuator must be stable
enough to ensure that correct operation can take place.
b
Always use reliable mounting elements that can only be removed using tools.
b
If misalignment results in an opening on the physical guard, this must not impair
the protection that is provided.
5.2 Unpacking
b
Chec
k the components for completeness and the integrity of all parts, see "Scope
of delivery", page 44.
b
Please contact your respective SICK subsidiary should you have any complaints.
5.3 Mounting
Selecting the mounting location
If the machine documentation does not specify the mounting location, select one care‐
fully:
b
When the protective device is closed, the sensor and actuator must be located
opposite each other at assured switch-on distance S
ao
or closer (see "Sensing
ranges", page 40).
b
Select a mounting location that allows the sensor and actuator to be accessed for
maintenance work and protects them against damage.
b
If possible, mount the sensor and actuator on non-ferrous subsurfaces and at a
distance from metallic parts in order to avoid affecting the sensing range. If this is
not possible, the effect on the safe switch on distance S
ao
and the safe switch off
distance S
ar
must be checked.
