connects the metal conduit to safety ground.
For installation with a power cable, make sure that the power cable is:
• Less than 3 m (10 ft) in length
• Rated sufficient for the supply voltage and current.
• Rated for at least 70 °C (158 °F) and applicable to the installation environment
• Not less than 1.5 mm
• A power cable with a three-prong plug (with ground connection) that is applicable to the supply
connection
• Connected through a cable gland (strain relief) that holds the power cable securely and seals the
enclosure when tightened
• Does not have a locking type device on the plug
