0.5–0.6 N ⋅ m (4.4–5.3 lb ⋅ in.) of torque. Installing the Strain-Relief Bar The cFP-CB-1 is shipped with two strain-relief bars, one with a foam cushion for wires and one with grooves for jacketed cables. The cFP-CB-3 has one foam-cushion strain relief bar. The tie-wrap anchors on the connector block provide additional strain relief.
Figure 7. Installing the cFP-CB- x Thermocouple Wiring Compact FieldPoint thermocouple input modules can measure the temperature of the terminals on the cFP-CB-1 or cFP-CB-3 connector block. The modules use this measurement, called the temperature, to compensate for the thermoelectric cold junction voltages generated at these junctions.
