Conduit Connection and Wiring | Cooper Lighting ELPS502 specs

NOTE

In Class II and Class III and Simultaneous Presence locations, limit upward aiming of fixture to a maximum of 30º above horizontal. Greater upward aiming could lead to excessive dust buildup and dangerous overheating of the dust.

5.Repeat the proceeding steps if a second EVLA12 fixture is to be installed on the ELPS50 power supply enclosure.

6.Proceed to Section C for conduit connection and wiring instructions.

C. Conduit Connection and Wiring

1a. Connect enclosure to properly grounded conduit system, installing conduit sealing fittings as required by Section 501.15 and, if required, 502.15 of the National Electrical Code plus any other applicable codes.

1b. If cable is utilized, a cable sealing fitting must be installed as required by Section 501.15 of the National Electrical Code plus any other applicable codes.

NOTE: Refer to Step 2b, making sure that the “designated disconnect” housing is installed in the system.

WARNING

•To avoid explosion, all unused conduit openings must be plugged. Plug must engage a minimum of five full threads. Use PLG plugs supplied with the unit.

•To maintain explosionproof integrity, conduit sealing fittings MUST be installed in each attached conduit run (within eighteen inches of the ELPS50 power supply enclosure in Class I locations).

•To maintain explosionproof integrity in Class I areas, conduit sealing fittings are required on all conduit entrances (within eighteen inches of the ELPS50 power supply enclosure) for all remotely located emergency lighting fixtures.

2.Make all wiring connections following wiring diagram located on power supply battery bracket.

NOTE: Although generally not required, the interior assembly may be removed to facilitate wire pulling. Remove four (4) 1/4-20 screws and lock washers and disconnect wire leads at the pilot light and switch. DO NOT handle interior roughly or place it in an area where dirt, dust or grime will damage it. Replace as soon as all wiring has been pulled into enclosure.

WARNING

•To avoid explosion or personal injury, all electrical power must be turned OFF before and during installation and maintenance and installation area must be free of hazardous atmospheres.

Figure 4. ELPS50 Power Supply - Interior View

NOTE: If installing ELPS502, connection of lighting fixture supply leads is already

completed. Proceed to Step 2b.

2a. Connect EVLA12 lighting fixture(s) supply leads to terminals L+ (#6) and L- (#7) . See figures 3 and 4.

2b. Connect incoming AC power 120, 220/240 or 277 VAC, 50 or 60 Hz emergency light battery circuit through a “designated disconnect” switch.

NOTE: Insulation rating on 12V conductors must equal to that of the higher voltage

power supply leads in accordance with Article 300.3(C) of NEC.

Important: TO PROPERLY INSTALL AND OPERATE THE ELPS, YOU MUST INSTALL A SEPARATE DISCONNECT SWITCH. IF THE DISCONNECT SWITCH IS LOCATED IN THE HAZARDOUS AREA, YOU MUST INSTALL A CLASS I, DIVISION 1 RATED SWITCH. USE CROUSE-HINDS EDS2129 OR EDS2129GB FOR GROUP B APPLICATIONS. (See Warning below)

This Designated Disconnect Switch can be supplied as part of the ELPS502 emergency

light (Options S794 or Option S854).

Option S794 - Key operated designated disconnect as part of the ELPS502 emergency

light. See Step 2c below to continue supply wiring

Option S854 - Keyless Designated Disconnect as part of the ELPS502 emergency light.

See Step 2c below to continue supply wiring.

EDS2129 (EDS2129GB for Group B applications) - Designated Disconnect Remote

Mounted (not supplied). Install per the instructions supplied with the EDS2129(GB)

disconnect. Wire to terminals 8 and 9. See Step 2c to continue supply wiring.

WARNING

•To avoid explosion, a Designated Disconnect position with lock-in/lock-out is required for safe servicing of the completely wired unit. The lock-in/lock-out capability will help 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.

•To avoid explosion, the designated disconnect switch, Cooper Crouse-Hinds EDSC2129 (EDS2129GB for Group B applications) must be suitable for use in the hazardous locations in which it is installed.

2c. Connect 120 VAC primary (through designated disconnect) to terminal 120 (#3). Connect 220/240 VAC primary (through designated disconnect) to terminal 220/240 (#4). Connect 277 VAC primary (through designated disconnect) to terminal 277 (#5). Connect common to terminal COM (#2). Connect all equipment grounding conductors to terminal GRD (#1). Connect battery connector to circuit board. Verify that transformer connector is also connected to circuit board.
