Electrical connection
The connection of the equipment is via plug-in connectors, polarized to avoid mistakes when
plugged in. The connectors have screw terminals, as per VDE standards, to accept cables with
section of 1.5 mm
The pictures of the connections in this manual are always looking at the equipment from the
back.
To help in the wiring of the equipment, the description of the terminals is marked on a label
in the rear side of the device.
For the electrical installation it is recommended to use multiple conductor cables with
individual cable sections in the order of 0.25 to 0.5 mm
connect. It is better to maintain the cables with mains voltage (power supply) separated from
the cables with low level signals (4-20 mA, etc.).
To connect the cables, peel the outside insulation to free the inner cables.
recommended to put a terminal at the ends of the wires to avoid loose ends.
Then, screw the wires into the corresponding positions in the female aerial connector.
Finally, place each connector with its corresponding male connector on the rear side of the
converter.
IMPORTANT NOTE: In order to comply with the electrical safety requirements as per EN-
61010-1 (IEC 1010-1), the installation of the equipment must take into account the following:
•
The equipment must be installed in the front panel of an electrical mounting cabinet,
leaving only the front of the equipment accessible to the operator.
•
In case of AC power supply, a mains switch must be provided to disconnect the
equipment. This switch must be marked as the disconnecting device for the
equipment and be within easy reach of the operator.
•
The housing must not be opened when the instrument has mains supply
connected.
IMPORTANT NOTE: To ensure smooth operation of the equipment, it is recommended to
make the connection paying attention to the following points:
•
For the output signals, use shielded cable when possible.
•
Keep the cables away from strong sources of noise.
