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.
