WIRING
See wiring diagram. For output signal, use twisted pair or
cables with performance equivalent to 600V vinyl insulate cable.
For wiring in high or low temperature, use a wire or cable
suitable for such temperature. Use cables and wires which
meet atmospheric conditions. Take necessary measure to avoid
corrosion or damage of cables and wires.
Important
When mounting on a sensor head, do not overtighten the
screws.
