Chapter 6. MAINTENANCE AND INSPECTION

WARNING

Be sure to use this limit switch within the ranges specified on page 1 for certified explosion-protected
electrical equipment. Failure to do so may cause a serious accident.

CAUTION

After inspecting the limit switch, firmly tighten the cover and conduit.
Insufficient tightening because of corrosion, etc., not only results in the loss of sealing and insulating
performance, but also nullifies the switch’s explosion-proofing.
Individual parts of this limit switch cannot be replaced. Replace the entire switch.

To ensure safe use the limit switch must be inspected periodically.
Adjust the frequency of inspection depending on the service conditions.
