Chapter 2 Installing the ICA Range
Pre Installation
See Specification details in Chapter 8 for details of Environmental Approvals.
Carefully remove the ICA unit from its shipment box. Check that the unit is complete and undamaged.
The ICA units can be operated in any industrial environment providing the following limits are not exceeded.
The following installation practices are advised:
Minimise vibration
Do not mount next to strong electrical fields (transformers, power cables)
Ensure easy access to the module
Install electrical protection device as the unit is not internally fused – a short across the excitation terminals could
cause permanent damage
Always ensure the package is secure and protected
Figure 2.1 Dimensions
The module is designed to fit in the strain gauge pocket. Use the 2.1mm hole to secure the unit.
The mounting hole will accept an M2 screw or American equivalent #0-80.
Important Note: DO NOT USE #2 screw size.
Take care when soldering cables to the pads.
Use a temperature controlled soldering iron set to a maximum 330 ºC, for no longer than 2 seconds per pad. Excessive
heat or increased soldering time may result in damage to the PCB.
If changing the gain resistor 'R
The ICA1-6 solder pads are as shown in the following wiring diagrams:
Four pads for the strain gauge.
Power supply and output pads
Two pads for sink or source option (ICA4H only)
The fixing screw hole provides a ground connection to improve EMC performance by capacitively coupling the
electronics to the strain elements in the load cell
N.B The voltage between either of the power supply connections and the load cell chassis should not exceed 50 V. Any
leakage will be greater than 10 M ohms.
