SAVE THESE INSTRUCTIONS FOR FUTURE REFERENCEIF 1873ELPSM2 Light-Pak – ELPSM2 K50 replacement charger board andbattery kitInstallation & maintenance information! WARNINGTo prevent injury from electric shock, all power must be removed from theequipment 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 deviceThis 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 toindicate that the unit is charging. Once installed with supply power, the ELPSM2requires 15 hours to charge the battery. Once the unit has completed charging, theindicating light will stop blinking and go to steady.Every 12 months, the unit will automatically perform a 90 minute battery dischargetest. At the completion of the test, if it is determined not to have met the 90minute requirement or if the battery connection is not adequate, the pilot lamp willblink twice, indicating battery failure. Every 30 days, the unit will also automaticallyperform 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 forevaluation. This can be accomplished by performing the manual 90 minute run timetest. Refer to the MANUAL TESTING section on page 2 for instructions.! WARNINGEven after disconnect, batteries will still be live. To prevent electrical shockand explosion, take extra care not to touch leads together or to ground.Status indication Status description Status definitionNo light AC power removed from circuit* Steady light (no blinks) Fully charged or test in process* - * Light blinks once Battery charging**-** Light blinks twice Battery failure***-*** Light blinks three times Circuit failure****-**** Light blinks four times Lamp failureTable 1! IMPORTANTA DESIGNATED DISCONNECT SWITCH IS REQUIRED FOR SAFETY, TOPOWER THE ELPSM22 EMERGENCY LIGHT SYSTEM AND CHARGE THEBATTERIES.To avoid explosion, a designated disconnect switch with lock-in/lockout capabilityis required for safe servicing of the completely wired unit. The lock-in/lockoutcapability will prevent unauthorized opening of the circuit when the systemshould be functioning, and to help prevent energizing of the system while it isbeing serviced, minimizing the possibility of arcing in the battery circuit while theenclosure is open in a hazardous (classified) area.Units supplied with options S794 or S854 already have a disconnect switchinstalled in the enclosure. Standard units require a remote disconnect switch. Ifthe switch is also located in a hazardous area, you must install a Class I, Division1 rated switch. Use Crouse-Hinds series EDS2129 or EDSC2129.Figure 1. Wiring Diagram4. Remove black, white and yellow/green wires from terminal block. Then removeall field wiring from terminal block.5. Disconnect battery from chargerboard plug connector and removedisconnect switch lead wires fromthe red lead wire of the battery.6. Disconnect purple (L+) and yellow(L-) charger board lamp leads from3-pole Wago terminal.7. Disconnect black and red chargerboard indicator light leads from2-pole Wago terminal.8. Disconnect two (2) blue charger board test switch leads from 2-pole Wagoterminal.9. Remove four (4) 1/4-20 screws and lock washers that secure the mounting plateto the enclosure and remove old interior assembly. Retain mounting hardware.10. Install the new interior assembly inside your existing enclosure using the samefour (4) 1/4-20 screws and lock washers removed in Step 9. Torque screws to60 in.-lbs.11. Replace pilot light LED with new 2 volt LED provided. See pilot lightreplacement instructions on page 2.12. Reconnect purple (L+) and yellow (L-) charger board lamp leads to 3-pole Wagoterminal.13. Reconnect black and red charger board indicator light leads to 2-pole Wagoterminal.14. Reconnect two (2) blue charger board test switch leads to 2-pole Wagoterminal.15. Reconnect black, white and yellow/green wires to terminal block.16. Reconnect battery to charger board via plug connector and reconnectdisconnect switch lead wires to the red lead wire of the new battery. Forinstallation of disconnect switch lead wires, cut the red battery lead wireand attach a listed wire connector to both ends (rated 300V minimum) forconnection 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 backthe protective covering to expose the adhesive. Install the CID101 in upperportion 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.IF 1873 • 03/19 Copyright® 2019, Eaton’s Crouse-Hinds Division Page 1REMOVAL OF CHARGER ASSEMBLY1. Disconnect branch AC power at circuit breaker and lockout.2. Disconnect DC power by turning designated disconnect key or selector switchto “OFF”.3. After removing all AC and DC power to the equipment, remove all coverfasteners to gain access to the interior.! WARNINGTo prevent explosion, do not damage the flat joint surfaces. Do not usehammers or prying tools to open covers. Do not handle covers roughly, or placethem on surfaces that might damage or scratch the flat joint surfaces.
