Potential Electrocution Hazard. If this equipment is used outdoors or in potentially wet locations, a
Ground Fault Interrupt
device must be used for connecting the equipment to its mains power source.

Install the device in a location and position that gives easy access to the disconnect device and its operation.
Supply power to the instrument with conduit or a power cable. Make sure that a circuit breaker with
sufficient current capacity is installed in the power line. The circuit breaker size is based on the wire
gauge used for installation.
For installation with conduit:
• Install a local disconnect for the instrument within 3 m (10 ft) of the instrument. Put a label on the
disconnect that identifies it as the main disconnect device for the instrument.
• Make sure that the power and safety ground service drops for the instrument are 18–12 AWG and
the wire insulation is rated for 300 VAC or higher.
• Connect equipment in accordance with local, state or national electrical codes.
• Connect the conduit through a conduit hub that holds the conduit securely and seals the enclosure
when tightened.
• If metal conduit is used, make sure that the conduit hub is tightened so that the conduit hub
connects the metal conduit to safely 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. Refer to the requirements in
on page 3.
• Rated for at least 60 °C (140 °F) and applicable to the installation environment
• Not less than 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
