Page 8: Introduction
It is recommended that you carefully follow the instructions for programming the weight transmitter; performing actions not indicated in this manual could compromise the functionality of the scale.

Page 9: Transmitter Installation
Transmitter Installation Installation Requirements Observe the following conditions for correct installation of the transmitter and of the load receiver: • Flat, level support surface. • Stability and absence of vibrations. • Absence of aggressive dusts and vapours. • Absence of draughts. •... -
Page 10: Electrical Precautions
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. © Rice Lake Weighing Systems • All Rights Reserved... - Page 11 RECOMMENDED DISTANCES AND CABLE CLASSIFICATION Category I Category II Category III Category IV ≥ 3.94 in (100 mm) ≥ 7.87 in (200 mm) ≥ 19.66 (500 mm) Distance ≥ 3.94 in (100 mm) ≥ 19.66 (500 mm) ≥ 19.66 (500 mm) Fieldbus, LAN network (PROFIBUS or Ethernet).

Page 12: Grounding The System
Connect the serial cable shield to the earthing point (or earth bar) inside the panel. To avoid any undesired effects, the earth reference of the connection cable, power supply and transmitter must be at the same potential. © Rice Lake Weighing Systems • All Rights Reserved... - Page 13 GENERAL NOTES: • All earth cables must be of suitable length, so as to obtain an overall resistance of the earthing system of less than 1 Ω. • If the weighing system involves large and/or outdoor structures (weighbridges, silos, etc.): - the earth connection must be made by connecting the earth cables to an earth bar and the earth bar to the earth post with a cable having a cross-section of not less than 1-1/0 AWG (50 mm - the earth post must be placed at a distance of at least 33 ft (10 m) from the structure.

Page 17: Load Cell Installation
Load Cell Installation After carrying out the instructions for the platform or load receiver, the shielded cable from the cell(s) must be properly connected to the terminal block(s) of the transmitter (from CELL1 to CELL4; see page 17). The transmitter has one channel (CELL1) for 6-wire connection to load cells (using the REFERENCE), while for the remaining channels (CELL2, CELL3, CELL4) only 4-wire connection is allowed. -
