Overview
Install the Yoke using the instructions that follow. Images
show a small (fos4PL8 or fos4PD8) fixture, but the instructions
are the same for all fos/4 Panel models.
WARNING: In addition to primary suspension, attach a safety cable (or other
approved safety device) to the fixture. Safety cables must be rated to support ten
times the fixture weight. Consult local standards to ensure that safety cables
meet all requirements.
Follow all safety precautions described in the fos/4 Panel User Manual , which is
available for download at etcconnect.com.
AVERTISSEMENT : En plus de la suspension principale, fixez une chaîne de
sécurité (ou tout autre dispositif de sécurité homologué) au projecteur. Les
chaînes de sécurité doivent être en mesure de supporter dix fois le poids du
projecteur. Consultez les normes locales pour vous assurer que les câbles de
sécurité respectent toutes les exigences.
