 Atmospheric pressure is introduced into an instrument via the
cable. If the cable is pressed due to a clamp, bush, or extreme
bend in the middle of the cable, or if the cable is long, the
exhaustion of pressure takes time. In this case, an output error
may be caused because of pressure within the case or a change
in temperature. Conduct wiring not to seal the cable end with
tape or adhesive.
 Be sure to select and use a transmission cable with an
appropriate outer diameter according to the size of the gland.
 Waterproof performance (equivalent to IPX7* (watertight)) is
ensured by using a cable conforming to the gland. Waterproof
performance is also affected by how you tighten the terminal box
lid and install a wire inlet.
 Be sure to check the waterproof performance when using
commercially available glands or cable conduits instead of the
supplied gland parts.
 Waterproof performance equivalent to IPX7 is guaranteed only
when the components are properly assembled. So, please check
it carefully.
* IPX7 (provision of protecting temporary immersion into water): Submerge the main unit in a tank with a
depth of 1 m for 30 minutes to check that the unit is not flooded (the amount of water causing harmful
effects is not intruded).
