Appendix C
DALI Option Card
Overview
The DALI Control option card (ERP-DALI) controls 24 loops of 64 DALI compatible fluorescent
ballasts in broadcast mode. This appendix provides instructions for the installation of this card.
Note:
the 0–10V Dimming Control option card (ERP-LVD) or the DALI Control option card
(ERP-DALI), but not both in the same panel.
Installation
WARNING:
power to the panel before working inside could result in serious injury or
death.
AVERTISSEMENT :
panneau sans avoir déconnecté le courant peut entrainer des blessures
graves, voire mortelles.
De-energize main feed to the panel and follow appropriate Lockout/Tagout
procedures as mandated by NFPA 70E. It is important to note that electrical
equipment such as relay panels can present an arc flash hazard if improperly
serviced. This is due to the high amounts of short-circuit current available on
the electrical supply to this equipment. Any work must comply with OSHA
Safe Working Practices.
Note:
control terminations are complete to reduce the likelihood of damage to the option
card.
The DALI ballast is powered by an external DALI loop power supply which is supplied by
•
others. This supply is internally connected to the Echo Relay Panel Mains Feed. The number
of power supplies needed for each DALI loop, is based on the connected load.
The ERP-DALI can control up to 64 DALI compatible fluorescent ballasts per DALI loop.
•
Each of the 24 DALI loops are linked one-to-one with a relay panel circuit for power
•
control.
Each output connection is labeled on the removable screw terminal bus connectors. The
removable connectors accept 0.25–4 mm
