When properly installed, the following raintight ELPS emergency lighting systems are UL and cUL Listed for use in: • ELPS50 Power Supply - Class I, Division 1, Groups B, C & D • ELPS502 - Class I, Division 1, Groups B, C, D Exit sign not UL/cUL • ELPS502 (EXS/EXD) - Class I, Division 1 & 2, Groups C, D (group B when ordered with GB suffix) All ELPS emergency lighting systems are suitable for use in Class II, Division 1, Groups E, F, G and simultaneous presence hazardous (classified) areas as defined by the National Electrical Code®. The ELPS50 power supply consists of a battery supply and battery recharging system housed inside a hazardous area enclosure with all the circuitry to automatically turn on emergency DC lighting fixture(s) when the normal power supply fails. A pilot light indicates when normal power is being supplied to the unit. A “push-to-test" push button switch is provided for periodic testing of the unit. Detail indication logic is given below: No Light AC power is removed from circuit • Steady Light (No blinks) Fully Charged • Light Blinks Once Charging • - • Light Blinks Twice Battery Failure • - • - • Light Blinks Three Times Circuit Failure 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 ELPS requires 72 hours to charge the battery. Once the unit has completed charging, the indicating light will stop blinking and go to steady. Every six months, the unit will automatically perform a 90minute battery discharge test. At the completion of the test, if it is determined not to have met the 90 minute requirement, the indicating lamp will display circuit failure (3 blinks). At any time, if the battery connection is not adequate the indicating lamp will display a battery failure (2 blinks). The EVLA12 lighting fixture is a factory sealed assembly housing a single halogen lamp/reflector light source. ELPS EVI and ELPS EVA GB Exit Signs are factory sealed with a single incandescent light source. Lamps are included with all fixtures. The EVLA12 is suitable for NEMA 4X locations when remote mounted (not installed on an ELPS Power Supply) and supplied with a NEMA 4X breather/drain. RATINGS ELPS50 Power Supply: Input -120, 220/240 and 277 VAC ± 5%, 50 or 60Hz -0.5 Amperes maximum Output -12 VDC; 2.5 Amperes -28 Watts for 1. hours (ELPS502) -29 Watts for 1. hours (ELPS502 EXS/EXD) Ambient Temp: -0.C to 40.C Lamp Fixtures: EVLA12 ELPS EVI/ELPS EVA GB Input -12 VDC -12 VDC Ambient Temp. -55.C maximum -40.C maximum Operating Temp. Code -Class I - T4A; -Class I - T4 -Class II, III - T3C -Class II, III - T3C -Simultaneous Presence - T3C NOTE: Ambient temperature at which ELPS50 power supply is rated is 0.C to 40.C to maximize battery capacity. EVLA12 lighting fixtures are permitted in higher, 55.C ambient temperature areas for more freedom in selecting remote installation location.

IMPORTANT Emergency lighting system should be installed, inspected, operated, and maintained by qualified and competent personnel. WARNING To avoid personal injury, electric shock and equipment failure: 1. Do not use this equipment for other than intended use. 2. Do not use accessory equipment not recommended by the manufacturer. 3. Electrical power must be turned OFF before and during installation and maintenance. 4. Equipment should be mounted in locations and at heights where it will not readily be subjected to tampering by unauthorized personnel. 5. Do not mount near heat producing equipment. 6. In Class I areas, install and seal all equipment in accordance with the National Electrical Code articles pertaining to Hazardous (Classified) Locations, plus any other applicable codes. 7. Install only wiring systems with an equipment grounding conductor (which may be the conduit system) to supply the ELPS. 8. two single-pole “Designated Disconnect” switches must be installed to disconnect the battery circuit and the supply circuit for safety in maintenance and servicing. 9. Free installation area of hazardous atmospheres before wiring. 10. Observe all battery handling precautions contained herein. 11. Hammers or prying tools must not be allowed to damage the flat joint surfaces of the ELPS50 power supply housing. Do not handle covers roughly, or place them on surfaces that might damage or scratch the flat joint surfaces. 12. To avoid shattering: Do not operate lamp in excess of rated voltage, protect lamp against abrasion and scratches, and against liquids when lamp is operating. Dispose of lamp properly.
