3 – INSTALLATION AND USE WARNING
3.1 – USE ALLOWED
The instrument has been projected and manufactured as measuring and control device to be used according to EN61010-1
approval.
The use of the instrument for applications not expressly allowed by the above mentioned rule has to adopt all the necessary
protective measures.
The instrument CAN’T be used in ambient with dangerous atmosphere (flammable or explosive) without a proper protection.
The user has to take care that EMC rules are respected, also after the instrument installation, possibly using proper filters.
Whenever a failure or a wrong functioning of the device may cause dangerous situations for persons, thighs or animals we
remind that the plant has to be equipped with additional electromagnetic devices in order to grant the safety.
3.2 – MECHANICAL MOUNTING
The instrument, in DIN case 48 x 48 mm, is designed for flush-in panel mounting.
Make a hole 45,5 x 45,5 mm and insert the instrument, fixing it with the provided special bracket.
We recommend to mount the gasket to obtain the front protection degree as declared. Do avoid to place the instrument in
ambient with very high humidity or dirt that may create condensation or introduction into the instrument of conductive
substances.
Ensure the adequate ventilation to the instrument and avoid the installation within boxes where are placed devices which
may overheat or have as a consequence the instrument’s functioning at higher temperature than allowed and declared.
Connect the instrument as far as possible from source of electromagnetic disturbances so as motors, power relays, relays,
electrovalves,etc. The instrument is removable from its housing by the front side : is recommended to disconnect the power
supply from the instrument when it’s necessary to effectuate this operation.
3.3 – ELECTRICAL CONNECTION
Carry out the electrical wiring connecting only one wire for each terminal , according to the following diagram, checking that
the power supply is the same as indicated on the instrument and the loads current is not higher than the maximum current
admitted. The instrument, being a built in equipment with permanent connection into a cabinet, is not equipped neither with
switches nor with internal devices protecting from overcurrent : the installation shall employ a two-phase circuit-breaker,
placed as near as possible to the instrument, located in a position easily reachable by the user and marked as instrument
disconnecting device.
It's recommended, furthermore, to properly protect all the electric circuits connected to the instrument, with devices (ex. fuses)
proportionate to the circulating currents. It's strongly recommended to use cables with proper insulation, according to the
working voltages and temperatures. Furthermore, the input cable of the probe has to be kept separate from line voltage
wiring. If the input cable of the probe is screened, it has to be connected on the ground with only one side. It is advisable to
check that the parameters are those desired before connecting the outputs to the actuators so as to avoid malfunctioning .
Whenever a failure of the instrument could cause dangerous or damaging situations, it should be kept in mind that the plant
has to be provided with additional devices to ensure the safety.
GREISINGER and its legal representatives do not assume any responsibility for eventual damages to persons, things or
animals deriving from violation wrong or not proper use or in any case not conforming with the instrument’s features.
