10. Install the CID101 corrosion inhibitor device included with kit by peeling back the
protective covering to expose the adhesive. Install the CID101 in upper portion inside
enclosure wall.
REMOVAL OF EXISTING CIRCUIT ASSEMBLY
(For units made AFTER October, 2005).
1. Disconnect branch AC power at circuit
breaker and lockout.
2. Disconnect DC power by turning
designated disconnect key or selector
switch to "OFF".
3. After removing all AC and DC power to
the fixture, remove all cover fasteners
to gain access to the interior.
4. Disconnect wire leads at the pilot light and test button and remove the four (4) 1/4-20
screws and lock washers on the aluminum backplate. Remove the old interior
assembly and set aside.
5. Disconnect all incoming connections from the terminal block and terminals L+ and L-
from the circuit board.
6. For units made before September 2012, only disconnect all incoming connections
from terminals GND through L-.
7. Install the new interior assembly inside your existing enclosure using the same four (4)
1/4-20 screws and lock washers removed in Step 4.
8. Replace pilot light LED with new LED provided.
9. Make all wiring connections following the wiring diagram located in the new assembly
(also see Figure 1).
10. Install the CID101 corrosion inhibitor device included with kit by peeling back the
protective covering to expose the adhesive. Install the CID101 in upper portion inside
enclosure wall.
CONNECT AC POWER AND TEST SYSTEM
1. Test wiring for correctness with continuity checks and also for unwanted grounds with
insulation resistance tester.
2. Close cover and securely tighten all cover bolts and nuts to 30 ft.-lbs. torque, making
certain that no cover bolts are omitted.
3. Connect AC power and allow ELPS system to charge for 72 hours before conducting
any tests. Do not disconnect AC power or depress the "Push-To-Test" button until the
unit is fully charged. The LED indicator lamp will illuminate steadily (no blinking) when
the ELPS is fully charged.
4. Test the emergency lighting system for proper operation. Turn on the designated
disconnect switch and observe: "Main Power ON" indicating light should be "ON" and
the EVLA12 emergency light(s) should be "OFF".
5. Press the "Push-To-Test" indicating push button switch and observe: "Main Power ON"
light should be "OFF" and the EVLA12 emergency light(s) should be "ON".
6. Lock the designated disconnect switch "ON" to prevent unauthorized persons from
turning system "OFF".
7. Conduct periodic testing as outlined in Instruction Manual IF 1072 (before October,
2005) and IF 1510 (after October, 2005) as supplied with the unit when originally
installed.

Part Number
Interior Assembly ELPS K50
Place these instructions (in protective plastic envelope provided) in a safe, convenient
location attached to or near the emergency lighting fixture.
MAINTENANCE
1. Conduct periodic testing in accordance with local authority and Periodic Testing
section of these instructions.
2. Clean fixture lens and exterior surfaces periodically. We recommend every three (3)
months or more frequently, if appropriate.
3. Frequent interior inspection should be made. A schedule for maintenance check
should be determined by the environment and frequency of use. It is recommended
that it should be at least once a year.
4. Perform visual, electrical, and mechanical checks on all components on a regular
basis.
•
Visually check for undue heating evidenced by discoloration of wires
or other components, damage or worn parts, or leakage evidence by
water or corrosion in the interior.
•
Electrically check to make sure that all connections are clean and tight.
•
Mechanically check that all parts are properly assembled.
5. Do not attempt field replacement or repair of ELPS50 power supply cover gasket.
Instead, remove damaged gasket and continue to use cover without gasket. This will
assure safety for use in Class I and Class II hazardous (classified) locations.
However, the enclosure will not be raintight.
WARNING
To avoid explosion, do not damage 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
Older circuit boards are wired to normally closed contacts. Replacement circuit
boards must be wired to normally open contacts.
CAUTION
To avoid explosion, clean both flat joint surfaces of body and cover before closing.
Dirt or foreign material must not accumulate on flat joint surfaces. Surfaces must
seat fully against each other to provide a proper explosionproof seal.
WARNING
To avoid explosion always disconnect primary power source using designated
disconnect switch before opening enclosure for inspection or service.
