Electrocution hazard. In order to maintain the NEMA/IP environmental ratings of the enclosure, use
only conduit fittings and cable glands rated for at least NEMA 4X/IP66 to route cables in to the
instrument.
To keep the environmental rating and for safety:
• Make electrical cable connections through the cable strain reliefs. To supply power with conduit,
replace a cable strain relief with a conduit hub. Seal the conduit with plumber's putty.
• Make sure that the diameter of the cables used is 4.3 to 11.4 mm (0.17 to 0.45 in.) so that the
cable strain reliefs hold the cables securely when tightened. Use 24 to 12 AWG to connect to the
terminals.
• Do not put more than one cable in a cable strain relief.
• Close all enclosure openings that are not used with cable strain reliefs or hardware (not
conductive) approved by local electrical codes. Seal the cable strain reliefs that are not used with
rubber cords (supplied) or cables.
Items to collect:
• Screwdriver, phillips
• Screwdriver, flat-head, small
• Wrench, 8.7 mm (11/32 in.)

Connect to AC power with the manufacturer/customer-supplied AC power cord or with conduit. Make
sure that a circuit breaker with sufficient electrical current capacity is installed in the power line.
Installation with a power cord
For installation with a power cord, make sure that the power cord is:
• Less than 3 m (10 ft) in length
• Rated for 300 VAC, 10 A minimum
• Rated for at least 70 °C (158 °F) and applicable to the installation environment
• If installed outdoors, the power cord jacket insulation is rated for outdoor use
• Not less than 0.82 mm
2
(18 AWG) with applicable insulation colors for local code requirements
• 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
• Make sure that the power cord plug is near the instrument and is easily accessible
