Operating Instructions
Precision Single Limit Switches N1A
Inspection of the following is necessary to ensure
trouble-free long-term operation:
f
correct switching function
f
secure mounting of all components
f
precise adjustment of trip dog in relation to single
limit switch
f
damage, heavy contamination, dirt and wear
f
sealing of cable entry
f
loose cable connections or plug connectors.
Information : The year of manufacture can be seen
in the bottom, right corner of the type label.
Exclusion of liability and warranty
In case of failure to comply with the conditions for
correct use stated above, or if the safety instruc-
tions are not followed, or if any servicing is not
performed as required, liability will be excluded and
the warranty void.
Notes about
The following information applies to devices
with cable entry:
For use and applications as per the requirements
of
, a copper wire for the temperature range
60/75 °C is to be used.
The following information applies to devices
with plug connector:
For use and applications as per the requirements of
, a class 2 power supply according to UL1310
must be used. Connection cables for safety switches
installed at the place of use must be separated
from all moving and permanently installed cables
and un-insulated active elements of other parts
of the system which operate at a voltage of over
150 V. A constant clearance of 50.8 mm must be
maintained. This does not apply if the moving cables
are equipped with suitable insulation materials which
possess an identical or higher dielectric strength
compared to the other relevant parts of the system.
