ELPSM2 Light-Pak – ELPSM2 K50 replacement charger board and
battery kit
Installation & maintenance information
!
WARNING
To prevent injury from electric shock,
all power must be removed from the
equipment during maintenance.
ELPSM2 K50 KIT CONSISTS OF:
(1) charger board and battery assembly with mounting plate
(1) IF 1873 instructions
(1) sealed NiCad battery
(1) 2 volt LED for pilot light
(1) CID101 corrosion inhibitor device
This kit includes a new LED indicating lamp that gives a visual status of the unit.
Details indicating LED logic is given below:
Immediately after supply power is initiated, the indicating lamp will blink/pulse to
indicate that the unit is charging. Once installed with supply power, the ELPSM2
requires 15 hours to charge the battery. Once the unit has completed charging, the
indicating light will stop blinking and go to steady.
Every 12 months, the unit will automatically perform a 90 minute battery discharge
test. At the completion of the test, if it is determined not to have met the 90
minute requirement or if the battery connection is not adequate, the pilot lamp will
blink twice, indicating battery failure. Every 30 days, the unit will also automatically
perform a 30 second self-test. If the battery, board or lamp has been compromised,
the indicator light will blink accordingly.
For battery warranty compliance, the unit must be discharged every 6 months for
evaluation. This can be accomplished by performing the manual 90 minute run time
test. Refer to the MANUAL TESTING section on page 2 for instructions.
!
WARNING
Even after disconnect, batteries will still be live.
To prevent electrical shock
and explosion,
take extra care not to touch leads together or to ground.

IMPORTANT
A DESIGNATED DISCONNECT SWITCH IS REQUIRED FOR SAFETY, TO
POWER THE ELPSM22 EMERGENCY LIGHT SYSTEM AND CHARGE THE
BATTERIES.
To avoid explosion, a designated disconnect switch with lock-in/lockout capability
is required for safe servicing of the completely wired unit. The lock-in/lockout
capability will prevent unauthorized opening of the circuit when the system
should be functioning, and to help prevent energizing of the system while it is
being serviced, minimizing the possibility of arcing in the battery circuit while the
enclosure is open in a hazardous (classified) area.
Units supplied with options S794 or S854 already have a disconnect switch
installed in the enclosure. Standard units require a remote disconnect switch. If
the switch is also located in a hazardous area, you must install a Class I, Division
1 rated switch. Use Crouse-Hinds series EDS2129 or EDSC2129.
Figure 1. Wiring Diagram
4.
Remove black, white and yellow/green wires from terminal block. Then remove
all field wiring from terminal block.
5.
Disconnect battery from charger
board plug connector and remove
disconnect switch lead wires from
the red lead wire of the battery.
6.
Disconnect purple (L+) and yellow
(L-) charger board lamp leads from
3-pole Wago terminal.
7.
Disconnect black and red charger
board indicator light leads from
2-pole Wago terminal.
8.
Disconnect two (2) blue charger board test switch leads from 2-pole Wago
terminal.
9.
Remove four (4) 1/4-20 screws and lock washers that secure the mounting plate
to the enclosure and remove old interior assembly. Retain mounting hardware.
10. Install the new interior assembly inside your existing enclosure using the same
four (4) 1/4-20 screws and lock washers removed in Step 9. Torque screws to
60 in.-lbs.
11. Replace pilot light LED with new 2 volt LED provided. See pilot light
replacement instructions on page 2.
12. Reconnect purple (L+) and yellow (L-) charger board lamp leads to 3-pole Wago
terminal.
13. Reconnect black and red charger board indicator light leads to 2-pole Wago
terminal.
14. Reconnect two (2) blue charger board test switch leads to 2-pole Wago
terminal.
15. Reconnect black, white and yellow/green wires to terminal block.
16. Reconnect battery to charger board via plug connector and reconnect
disconnect switch lead wires to the red lead wire of the new battery. For
installation of disconnect switch lead wires, cut the red battery lead wire
and attach a listed wire connector to both ends (rated 300V minimum) for
connection to disconnect switch lead wires.
17. Connect all field wiring to terminal block.
18. Verify all wiring connections are correct per the wiring diagram (see Figure 1).
19. 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.
20. Re-install all cover fasteners. Torque to 25-30 ft.-lbs.
21. Reconnect DC power to the equipment at disconnect switch, if applicable.
22. Unlock and reconnect branch AC power at circuit breaker.
