1. Safety instructions
These instructions are part of the device. They contain texts and
drawings concerning the correct handling of the controller and must
be read before installation or use.
Observe the information of these mounting and installation instructions as well as
all documentation referred to. Non-observance of the instructions, operation
which is not in accordance with the intended use, incorrect installation or
handling can seriously affect the safety of people and equipment.
These instructions are intended for "authorised" persons according to EMC and
Low-Voltage directives. The controllers must be installed and commissioned by a
qualified electrician (programmer or service technician).
It must be ensured that the external voltage is generated and supplied according
to the criteria for safe extra-low voltage (SELV), since this voltage is supplied
without further measures to supply the connected controller, the sensors and the
actuators.
The wiring of all signals in connection with the SELV circuit of the device must
also meet the SELV criteria (safe extra-low voltage, safe electrical separation from
other dangerous contact circuits).
If the supplied SELV voltage is externally grounded (SELV becomes PELV), the
responsibility lies with the user and the respective national installation regulations
must be complied with. All statements in the operating instructions refer to the
unit which is not grounded with respect to the SELV voltage.
The connection terminals may only be supplied with the signals indicated in the
technical data and/or on the unit label and only the approved accessories of ifm
electronic gmbh may be connected.
The device can be operated within a wide temperature range according to the
technical specification indicated below. Because of the additional internal heating
the housing walls can have high perceptible temperatures when touched in hot
environments.
In case of malfunctions or uncertainties please contact the manufacturer.
Tampering with the device can seriously affect the safety of people and
equipment. It is not permitted and leads to the exclusion of liability and warranty.
Observe the notes on function and features, programming and commissioning
of controllers of the series "SafetyController R 360" (see page 3).
