Eaton ELPSM22 Installation & Maintenance Information

IF 1875 • 03/19 Copyright® 2019, Eaton’s Crouse-Hinds Division Page 3! NOTEIn Class II, Class III and Simultaneous Presence locations, limit upward aiming ofequipment to a maximum of 30º above horizontal. Greater upward aiming couldlead to excessive dust build-up and dangerous overheating of the dust.C. Conduit connection and wiring11. Connect enclosure to properly grounded conduit system, installing conduitsealing fittings as required by Section 501.15 and, if required, 502.15 of theNational Electrical Code plus any other applicable codes.12. If cable is utilized, a cable sealing fitting must be installed as required bySections 501.15 and 502.15 of the National Electrical Code plus any otherapplicable codes.NOTE: Refer to Step 15, making sure that the “designated disconnect” housing isinstalled in the system.13. Make all wiring connections following wiring diagram located on power supplybattery bracket.NOTE: If installing ELPSM22, connection of lighting equipment supply leads is alreadycompleted. Proceed to Step 15.14. Connect the blue lamp lead to the purple (L+) charger board lead via the 3-poleWago terminal and connect the yellow lamp lead to the yellow (L-) chargerboard lead. See figures 3 and 4.! WARNING• To avoid explosion, all unused conduit openings must be plugged. Plugmust engage a minimum of five (5) full threads. Use PLG plugs suppliedwith the unit.• To maintain explosionproof integrity, conduit sealing fittings MUSTbe installed in each attached conduit run (within eighteen inches of theELPSM20 power supply enclosure in Class I locations).• To maintain explosionproof integrity in Class I areas, conduit sealingfittings are required on all conduit entrances (within eighteen inches ofthe ELPSM20 power supply enclosure) for all remotely located emergencylighting equipment.Figure 3. Wiring Diagram! WARNINGTo avoid explosion or personal injury, all electrical power must be turned OFFbefore and during installation and maintenance and installation area must be freeof hazardous atmospheres.15. Connect a designated disconnect switch for ELPSM2 emergency lightingsystem as follows:NOTE: Insulation rating on 12V conductors must equal to that of the higher voltagepower supply leads in accordance with Article 300.3(C) of NEC.Important: TO PROPERLY INSTALL AND OPERATE THE ELPSM2, YOU MUSTINSTALL A SEPARATE DISCONNECT SWITCH. IF THE DISCONNECT SWITCHIS LOCATED IN THE HAZARDOUS AREA, YOU MUST INSTALL A CLASSI, DIVISION 1 RATED SWITCH. USE CROUSE-HINDS SERIES EDS2129 OREDSC2129.(See Warning below)This designated disconnect switch can be supplied as part of the ELPSM22emergency light (option S794 or option S854).Option S794 – key operated designated disconnect as part of the ELPSM22emergency light. See Step 16 below to continue supply wiring.Option S854 – keyless designated disconnect as part of the ELPSM22 emergencylight. See Step 16 below to continue supply wiring.EDS2129 or EDSC2129 – Designated Disconnect Remote Mounted (not supplied).Install per the instructions supplied with the EDS2129 or EDSC2129 disconnect.Wire in series according to the wiring diagram in Figure 3 by cutting the red batterylead wire and attaching a listed wire connector to both ends (rated 300V minimum)for connection to disconnect switch lead wires. See Step 16 to continue supplywiring.16. Connect AC power to terminal block via the ground “G”, line “L” and neutral“N” Wago terminals.17. Test wiring for correctness with continuity checks and also for unwantedgrounds with insulation resistance tester.18. Allow the ELPSM2 to charge under line power for 15 hours before initiating anytesting of the emergency operation of the lights.D. Complete installation19. Install CID101 corrosion inhibitor device (supplied loose in ELPSM20).Recommended location is on the bottom wall between “Main Power On” pilotlight and 1” NPT tapped hole. Refer to CID101 instructions for installation.! WARNING• To avoid explosion, a designated disconnect position with lock-in/lockoutis required for safe servicing of the completely wired unit. The lock-in/lockout capability will help prevent unauthorized opening of the circuitwhen the system should be functioning and to help prevent energizing ofthe system while it is being serviced, minimizing the possibility of arcingin the battery circuit while the enclosure is open in a hazardous (classified)area.• To avoid explosion, the designated disconnect switch, Crouse-Hindsseries EDSC2129, must be suitable for use in the hazardous locations inwhich it is installed.Figure 4! WARNINGTo avoid electrical shocks, install luminaire only on systems with an equipmentgrounding conductor.! NOTEUnit needs to charge for 15 hours before conducting any tests. Do notdisconnect AC power until unit is fully charged.! CAUTIONTo avoid explosion, clean both flat joint surfaces of body and cover beforeclosing. Dirt or foreign material must not accumulate on flat joint surfaces.Surfaces must seat fully against each other to provide a proper explosionproofseal.
