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.
