Note:
Installation must follow all national and local codes for electrical equipment.
Note:
Normal and emergency wiring cannot be contained in the same conduit according
to NEC 700.10(B).
Emergency drivers and luminaires require two branch circuit connections. These inputs have the
following functions:
1. Normal branch circuit to sense failure of the normal supply. Connect to Sense Input
connector.
2. Normal/Emergency branch circuit providing power to the luminaire in both conditions.
Connect to Maintained Input connector.
Sense detects when power is lost and forces the luminaire to a full-on state, powered by the
emergency supply through the Constant Power input. Control of the luminaire will not be available
until the sense input has been restored.
WARNING:
Do not mix 120 V and 277 V between the sense and emergency
feeds.
AVERTISSEMENT :
Ne pas inverser les alimentations à 120 V et 277 V entre
les alimentations de détection et de secours.
WARNING:
Sense (normal) and Maintained (normal/emergency) feeds must
have the same phase. The diagram below shows the recommended installation.
AVERTISSEMENT :
Les alimentations de détection (normale) et d’entretien
(normal/secours) doivent être sur la même phase. Le schéma ci-dessous présente
l’installation recommandée.
