WARNING
Handling precautions:
(1) Potential electrostatic charging hazard Electrostatic charge may cause an explosion hazard.
Avoid any actions that cause the generation of electrostatic charge, e.g., rubbing with a dry
cloth.
(2) With sensors that have a solution ground tip made of titanium (-TN), ignition sources due to
impact and friction sparks are excluded.
(3) IEC60079-14 (Electrical installations in hazardous areas) requires a label indicating 'simple
apparatus', stick this label to this sensor if necessary.
