Installation Rice Lake Weighing Systems recommends the instrument and the platform (transducer) be installed on a flat level surface, that is stable and vibration free. Location Selection IMPORTANT The following should be considered when selecting a location for the equipment:...
Grounding the System For proper grounding and optimal functioning of the system, it is necessary to create a single point ground in proximity of the instrument on which to connect the ground of the instrument connected cables. Connect the ground point of the instrument, load cells and weighing structure directly to the ground bar of the electric panel or to a grounding rod.
Connection to the Load Cell After proper grounding of the platform and the load cell, connect the shielded cable from the load cell to the instrument ground. See Figure 1-1 on page The load cell terminal board of the instrument may be connected to the 6-wire load cell; 4-wire load cell must jumper sense to the excitation.

Operation Power Supply and Start Up The instrument must be powered with stabilized voltage at 12 VDC or 24 VDC supplied from an AC/DC external charger (not included) which should be connected to appropriately rated AC main voltage. To power the instrument, connect the two power supply cables to the appropriate terminal board (Figure 1-1 on page 3) on the side or the back of the instrument.
