Electrical precautions
• Use a regulated mains supply within ± 10% of the rated voltage.
• The electrical protections (fuses, etc.) are the responsibility of the installer.
• Observe the recommended minimum distances between cables of different categories
(see table on page 10)
.
• The following cables must comply with the maximum permissible lengths
(see table on page 10)
, they must be shielded and must
be inserted alone in metal conduits or pipes:
- the load cell extension cables;
- the signal amplifier cables;
- the cables for connecting the serial ports;
- the analog output cables.
• The cell or amplifier cables must have an independent input in the electrical panel. They must be connected (if possible) directly to
the terminal block of the transmitter without passing through the conduit with other cables.
• Fit “RC” filters:
- on the contactor coils;
- on the solenoid valve coils;
- on all devices that produce electrical interference.
• If condensation can occur inside the weight transmitter, it is advisable to keep the equipment powered at all times.
• Connections to load cells and any external device must be as short as possible.
• The cable ends (connectors, leads, terminals, etc.) must be installed correctly; the cable shielding must be kept intact until close to
the connection point.
• If the transmitter is placed inside an electrical panel, a shielded cable must also be used for the power supply.
