Wiring Precautions
1. Care must be taken to ensure that maximum voltage rating specified on the label is not exceeded.
2. For the panel-mount version, it is recommended that near the equipment an external fuse and an
external switch rated at 2A/250 VAC should be equipped.
3. Beware not to over tighten the terminals screws. The torque should not exceed 0.7 N-m ( 6.3
Lb-in or 7.1 Kg F-cm ).
4. Except the thermocouple wirings, all wirings should be stranded copper conductor with
maximum gauge 18 AWG.
5. Connect a grounding conductor with 1.6mm diameter minimum to provide protective grounding
prior to turning on the equipment.
