Installation 7
2.0 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.
2.1 Location Selection
The following should be considered when selecting a location for the equipment:
* Dust-free
* Free of strong breezes or vapors
* Moderate temperature and humidity (59 to 86°F and 40-70%)
* Use waterproof sheaths and couplings in order to protect the load cell cables
* Use a waterproof junction box to connect the cells
* Avoid welding with load cells installed
2.2 Electrical Precautionary Measures
The following electrical precautionary measures must be considered when installing this equipment:
* Main power supply must be restricted to within ± 10% of the rated voltage
* Electrical best practices must be observed by the installing technician
* Follow recommended minimal separation distances given for cable categories. See Section 2.3.
* The extension leads of the load cells, or signal amplifiers connecting to the serial ports and analog
output, must be within stated maximum lengths. See Section 2.3
* It is recommended that load cell cables are shielded and run in conduit at an acceptable distance from
power transmission lines to avoid signal interference and signal noise
* All cable not in conduit or otherwise shielded should be of minimal length and terminated as close to
conduit exit as possible to avoid extraneous signal noise
* If the instrument is situated inside an electric panel, the power supply cable must be shielded and as
short as possible, separate from every coil supply cable, inverter, electromotive force, etc. In addition,
dedicate an uncoupler transformer in order to feed the instrument only
* Install RC filters on the contact coils, solenoid valves and all devices producing electric disturbances
* It is recommended to leave the instrument powered on at all times to avoid condensation forming on
the inside of the instrument

2.4 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.
2.4.1 Instrument
Create a single point ground in proximity to the instrument, on which to connect the ground of the instrument and
the connected shielded cables (load cell cable, serial ports cables, etc.).
Example: use an end connector terminal block and connect this point to ground with a 4 mm2cable.
In the SCT-1100 indicator, connect the terminal 2 (GND) to earth with a ground cable having a diameter as large as
possible (maximum diameter supported: 2.5 mm²).
2.4.2 Load Cells and Junction Box
When the load cells are connected to the instrument through a junction box, the shielding of the cell cables and the
instrument must be connected to the grounding of the junction box.
When the load cells are directly connected to the instrument, the shielding of the cell cables must be connected to
the single point ground. Use a cable having a 4 mm² diameter, if the single ground is a few feet away; use a copper
cable having at least a 16 mm² diameter, for longer distances.
Use a ground plate of a length to obtain a total resistance of grounding lower than 1 Ω.
System cabling should be kept as short as possible to minimize noise potential. After exiting conduit or other
shielding, a ferrite should be used prior to conductor termination.
Figure 2-1. Grounding Example
Procedures not expressly described in this manual are considered improper use of the equipment.
Ensure the platform is level or the loading cells are resting evenly.
All connections must be made with respect to local zone and environment standards.
Follow the recommended electrical precautionary measures described in Section 2.2 on page 7.
Make sure that the grounding is made correctly. See Section 2.4 on page 8.

2.5 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 3.
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.
Sense is always enabled and must be jumpered to the same polarity excitation, when not using
6-wire load cell.
The sense compensates for drops in voltage in the part of the cable connecting the instrument to the load cell. This
is useful when the distance between the instrument and the load cell is greater than 32' (10 m). Normally this is
based on the load cell being used. When exceeding the length of the load cell cable, six wires must be used to
compensate for voltage drop. It is, however, recommended to use the cable supplied with the load cell and not to
modify it in any way.
