Assembly, electrical installation and inauguration, maintenance:
Assembly, electrical installation, inauguration, operation and maintenance of the device must be carried out by an qualified employee.
The electrical installation of the device must be carried out according to the respective country specific standards.
An incorrect assembly or adjustment could cause applicationally conditioned risks.
The device is maintenance free.
The voltage applied to the clamps may not exceed 50 V at devices of the variants _A0 or _AS and 35 V at devices of the variants _B0 to avoid damage of the
electronic.
All connections are polarity protected.
Use only shielded signal and measurement wires and install these wires separated from power leading wires.
Connect the shield only at one side to earth, ideally at the installation place of the device.
If inductive loads, e.g. relays are connected to the PNP output, an RC protection circuit must be used to avoid high voltage peaks, because they could influence
the properly function of the device
Safety notes:
If a device of the variant Ex KTM_A0 is installed and operated in a hazardous area, the general Ex construction standards (EN60079-14, VDE0165), this safety
notes and the enclosed EC conformity certificate must be observed.
The assembly of an Ex system must be carried out principally by specialist staff.
The devices meets II 1 G EEx ia IIC T4

The devices are conceived for measurement of temperatures in hazardous areas.
The measured medium may also be combustible liquids, gases, fogs or steams.
A warning marking points out to the dangers through electrostatic charging of the plastic housing and to the safety measures, that must be applied because of
this dangers in operation mode and especially in the case of maintenance activities.
