INSTALLATION
A. Install ELPS502 System or ELPS50 Power Supply
1. Select mounting location that will provide suitable strength and rigidity for supporting
power supply and attached lighting fixtures. Figure 1 shows the overall dimensions
and mounting dimensions for the four mounting feet.
Weights: ELPS502 System 50 lbs.
ELPS502 EXS/EXD System 60 lbs.
ELPS50 Power Supply 40 lbs.
EVLA12 Fixture 5 lbs.
2. Securely fasten enclosure to the mounting location using 3/8" diameter bolts or
screws.
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.
B. Attach and Adjust EVLA12 Lighting Fixture(s)
NOTE:If installing ELPS502, fixtures are already attached. Proceed to Step 5 to
adjust fixtures.
1. Remove pipe plug(s) from the 1" NPT tapped holes in the side(s) of the ELPS50
power supply enclosure where the EVLA12 fixture is to be installed.
NOTE:Remotely mounted EVLA fixtures can be mounted in a suitable splice box,
such as Crouse-Hinds EABT36, EABL36, or EABC36 that provides a 1" hub for
fixture attachment.
2. Thread light assembly into body being sure that the reducer fitting is engaged with the
body at least five full threads.
3. Using a 1-5/8” wrench, loosen Nut ‘A’, position lamp head in desired vertical position
and retighten to 58 lb.-ft. torque.
4. Using the same 1-5/8” wrench, loosen Nut ‘B’ and position lamp head in desired
horizontal position. Be sure to re-tighten Nut ‘B’ to 58 lb.-ft. torque.

IMPORTANT
The recommended mounting position is with the back wall of the enclosure
fastened to a vertical surface with the pilot light and push-to-test push button
located on the bottom of the enclosure.
IMPORTANT
Spacers are required between splice box and mounting surface to ensure
proper clearance for fixture hub rotation during installation. 11/8” dimension is
required between center line of mounting hub & face of mounting surface.
WARNING
To avoid electrical shock, electrical power must be turned OFF before and during installation and maintenance.
CAUTION
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.
NOTE
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.
CAUTION
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.
