Safety Precautions
WARNING
Be sure to use this limit switch within the ranges specified on page 1 for certified explosion-pro-
tected electrical equipment. Failure to do so may cause a serious accident.
To maintain explosion-proof performance, do not disassemble the limit switch, except for removing
the cover when wiring, or changing the direction of the lever or head. Otherwise it will not satisfy
explosion-proof specifications.
CAUTION
The environmental conditions for the safe use of this limit switch in hazardous atmospheres are de-
scribed in the product specification sheet. Use this limit switch within the allowable ranges for each
characteristic as stated in the specifications.
Check the limit switch periodically to make sure that it is operating normally.
If the cover or exterior of the limit switch has some abnormality (dent, large crack or tiny cracks, etc.)
replace the switch immediately. Failure to do so may result in an ineffective seal or loss of explosion-
proof performance.
Wiring should comply with “Recommended Practice for Explosion-Protected Electrical Installations
in General Industries.”
