Safety Precautions
WARNING
This product is not designed or rated for ensur-
ing safety of persons. Do not use it for such
purposes.
DIN Track Mounting Bracket (E8CC)
• Mounting
1. Fit the front part onto the bracket.
2. Press the rear part onto the bracket.
• Removing
3. Apply a flat-blade screwdriver to the rear hook. Then the
Pressure Sensor can be removed with ease.
Precautions for Correct Use
Do not use the product in atmospheres or environments that
exceed product ratings.
●
Mounting
Diaphragm
• If the diaphragm is damaged, the Pressure Sensor will not
operate properly. Do not insert a screwdriver or steel wire
into the interior of the pressure-sensitive parts through the
pressure inlet.
Mounting
• The pressure inlet has an R (PT)1/8 taper screw and an M5
female screw. Apply sealing tape around a screw that con-
forms to JIS Standards so that no pressure leakage will oc-
cur.
• Do not apply a tightening torque higher than 3.9 N·m.
• If the Pressure Sensor is directly connected to a conduit, be
sure to apply a wrench to the pressure inlet. Do not apply
the wrench to the plastic case.

Wiring
• If no linear output is used, cut off the black lead wire and ap-
ply insulation tape to the lead wire so that it will not come in
contact with any other terminal.
