Step 1. Mount the PXM350-ENC enclosure to a wall or a panel
Cut holes in the enclosure for wire conduit connections prior to the
installation of the meter in the enclosure. After running the wiring,
seal all holes properly to maintain the enclosure rating. If using
metallic conduit, bonding between the conduit connections is not
automatic and must be provided as a part of the installation.
Take care to protect the equipment from drill chips, filings, and other
contaminants when making the wire entry holes and mounting the
enclosure to prevent component damage or a future malfunction.
Use the included mounting hardware to attach the mounting feet
to the enclosure. Then mount the enclosure to the wall or the panel
using either a 4-point or 2-point configuration (hardware for mounting
to the wall/panel is provided by the installer). The 4-point configura-
tion is shown below. For a 2-point configuration, mount the feet
as shown, but rotate the bottom feet 180 degrees so that they are
flush against the back of the enclosure.
Step 2. Install PXM350 series meter onto DIN rail inside the
PXM350-ENC
The PXM350 series meter is shipped with a set of two DIN rail clips
included. These clips are already installed into the slots on the back
of the housing from the middle, moving outward. Stopping pegs
must face the underside of the housing.
Push the bottom of the meter onto the DIN rail until there is an
audible click.
