Electrical shock and/or fire hazards.
Install the instrument in accordance with local, regional and national regulations.
Externally connected equipment must have an applicable country safety standard assessment.
A local disconnect is needed for a conduit installation.
Make sure to identify the local disconnect clearly for the conduit installation.
For a cord-connected instrument, make sure to install the instrument so that the cord can be
disconnected easily from the supply socket.
Remove the access plugs
Install cables and conduit through the electrical access ports. Refer to
sealing plugs by pushing them out from inside the enclosure to unlock the seal, and then remove
completely by pulling from the outside. Remove knockouts as necessary from the electrical access
plate with a hammer and screwdriver. To keep the enclosure rating, put a cover on all ports that are
not used.
