SAFETY AND INSTALLATION INSTRUCTIONS
complete, undismantled products have to be sent to our
customer service.
General Installation Instructions
 Low-voltage cables should be installed physically sepa-
rate from SELV cables.
 Sensor and control signals must never be led through
the same cable as power supply or load connections.
Separate sensor or control cables should not be laid in
parallel to low-voltage cables over long distances.
 Appropriate measures (e.g. wire-end ferrules with plastic
collars) must be taken to secure flexible conductors
against splicing.
 If inductive loads (e.g. contactors) are connected, addi-
tional EMC interference suppression measures may have
to be taken during installation.
 Devices mounted on a socket may only be removed if
the power is off. The device may be damaged if it is
plugged in or extracted under power.
 Products containing a processor should - in case of mal-
function - first of all be disconnected from power (via the
circuit
breaker). After waiting for about a minute, the power
may be switched on again. This often solves the prob-

lem. If this is not the case, please contact our customer
service.
 All tekmar sensors take their auxiliary energy from the
connected control unit. Connecting a sensor directly to a
voltage source destroys the sensor and may endanger
persons.
 Temperature sensors may be checked with an ohmme-
ter. However, they must not be connected to the control
unit during the check. Refer to the technical data or in-
stallation instructions for resistance and temperature
values for the check.
