Establish an easily accessible location for installation and keep in mind that the cabling will be coming from the
bottom panel of the enclosure. Make the necessary holes in the panel for the vibration sensor cabling. Use the
supplied mounting feet to install the enclosure.
NOTE:
Be very careful when punching and/or drilling the enclosure as to not damage the internal metal, terminal
strips and printed circuit boards.
