2.4.1 Wiring Precautions
Care must be taken to ensure that the maximum voltage rating specified on the label is not exceeded.
For the panel-mount version, it is recommended that near an external fuse or an external switch rated
at 2A/250 VAC should be used.
Beware not to over tighten the terminals screws. The torque should not exceed 0.4 N-m (3.6 Lb-in or
4.0 Kg F-cm).
With the exception of the thermocouple wires, all wires should be stranded copper conductor with
maximum gauge of 18 AWG.
Connect a grounding conductor with 1.6mm diameter minimum to provide protective grounding prior to
turning on the equipment.
