Power supply
a) Before connecting the instrument, check that the the power supply tension is within the permitted limits and that
it corresponds to the one indicated on the tag.
b) Carry out the electrical connections with the instrument disconnected.
c) For the power line to instruments and sensors, a power supply line separate from that of the power is required :
it is necessary to use an isolating transformer.
d) The power line should forsee a device that separates the set fuses of the instruments and should not be used to
regulate, meters, etc.
e) If the network tension is very disordered (eg. from the change-over of the power units, motors, inverters,
welders,
etc.), use the appropriate filters of the network.
f) If an earth connection is needed, ensure that the plant has a good earth system: tension between neutral and
earth <1V and the resistance <6 Ohm.
Connections entries and exits
a) Physically separate the entry wires from those of the power supply, the exits and the power connections; use
twined and shielded wires with the display connected to the earth only at one point.
b) Connect the exits of adjustments, alarms (meters, electrovalves, motors, ventilators, etc.) assembling units RC
(resistance and condenser in series) parallel to the charged inductives that work alternatively.
Assembly of the instrument
To carry out the correct installation of the instrument, it is necessary to follow the shown procedure:
1. Insert the instrument in the opening provided.
2. Screw the screw on the fixing block.
3. Hook the block to the instrument through the joints.
4. Block the instrument by screwing the screws of the two blocks.
5. Then carry out the electrical connections.
To assemble several instruments placed side by side, it is necessary to follow the interaxes as shown in the
design.
The articles A and B can be read under space dimensions found in the present manual.
