Operating Instructions
Safety Switches NZ.VZ
Exclusion of liability and warranty
In case of failure to comply with the conditions for
correct use stated above, or if the safety regula-
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 application as per the requirements
of a copper wire for the temperature range
60/75 °C must be used.
The following information applies to devices
with plug connector:
This device is intended to be used and applied with
a Class 2 power source in accordance with UL1310.
Connecting 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 that
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 that possess an
identical or higher dielectric strength compared to
the other relevant parts of the system.

EU declaration of conformity

The declaration of conformity is part of the operating
instructions, and it is included as a separate sheet
with the device.
