When the inverter transfers into the emergency mode, the dimming relay contacts electrically open the 0-10 dimming reference signal forcing the luminaire to operate at full lumen output regardless of dimmer setting. GROUND WIRE PRIMARY UNSWITCHED INPUT AC INPUT FOR THE INVERTER - MUST BE UNSWITCHED. SELECT PROPER VOLTAGE FLYING LEADS ARE FOR THE NORMAL AC INPUT (SWITCHED OR UNSWITCHED) - SELECT PROPER GROUND WIRE - CONNECT FIXTURE SUPPLY GROUND AND UNIT GROUND IN ACCORDANCE WITH LOCAL AND NATIONAL CODES. IF USING A SECONDARY AC INPUT, SELECT PROPER VOLTAGE LEAD AND CAP UNUSED LEAD. USE A 277V RATED SWITCH IF CONNECTING TO 277V INPUT.

GROUND WIRE Diagram 2 - EM Dimming Signal The Dimming Relay contacts are electrically open during normal power conditions allowing your dimming signal to operate the luminaire in the desired, dimmed state. When the inverter transfers into the emergency mode, the dimming relay contacts electrically short the 0-10 dimming reference signal forcing the luminaire to operate at a reduced lumen output setting based on the dimmable driver being used. Verify operating results of the luminaire with the 0-10 volt reference signal shorted to assure the application and mounting height produce code-compliant egress lighting.
