WARNING<br />
F0801.EPS<br />
•All wiring shall comply with local installation<br />
requirements and local electrical code.<br />
• In hazardous locations, the cable entry devices<br />
shall be of a certified ATEX flameproof type,<br />
suitable for the conditions of use and correctly<br />
installed.<br />
• Unused apertures shall be closed with suitable<br />
flameproof certified blanking elements. (The<br />
plug attached is flameproof certified.)<br />
