Appendix B
0–10V Option Card
Overview
The 0–10V Dimming Control option card (ERP-LVD) is designed for LED drivers and fluorescent
ballasts. It sinks up to 400 mA current on each of its 24 outputs. Each channel output is linked
one-to-one with a relay circuit for power control and can control up to 50 ballasts.
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.
WARNING:
may not be fully isolated from high-voltage AC power. Do not assume that
0–10 V wiring is safe to touch, even when run as an NEC Class 2 signal. Test
for AC voltage to ground before terminating any 0–10 V control wiring to
the device.
AVERTISSEMENT :
ÉLECTROCUTION! Le câblage 0–10 V peut ne pas être complètement isolé du
courant alternatif haute tension. Ne supposez jamais que le câblage 0–10 V
peut être touché en toute sécurité, même s'il est utilisé avec un signal NEC
de Classe 2. Testez la tension alternative par rapport à la terre avant de
raccorder tout câblage de commande 0–10 V à l'appareil.
