fastened to a vertical surface with the pilot light and push-to-test push button
located on the bottom of the enclosure.
A Class I, Division 1 sealing fitting must be installed within 18 inches of the
conduit entry of the ELPS enclosure. Use Chico A or Chico SpeedSeal sealing
compound to seal the conduit entry.
3. Remove the cover bolts and nuts from two stud bolts, then lift off cover and carefully
set it aside to prevent damage to the flat joint and flange gasket.
NOTE: ELPS units have two stud bolts located at diagonally opposite corners of the
body to aid in positioning cover. Do not remove stud bolts.
4. Proceed to Section B to attach and/or adjust EVLA lighting fixtures.
To avoid damaging the flat joint surfaces, do not use hammers or prying tools to
open covers. Do not handle covers roughly, or place them on surfaces that might
damage or scratch the flat joint surfaces.
B. Attach and Adjust EVLA12 Lighting Fixture(s)
NOTE: If installing ELPS502, fixtures are already attached. Proceed to Step 5 to
adjust fixtures.
EVLA fixture head and arm are limited to no more than 180º of rotational
adjustment. Failure to adhere to this will result in damage to the internal wiring.
