Overview
The fos/4 Panel Pole-Operated Yoke allows
you to adjust the pan (blue cup) and tilt
(white cup) of the fos/4 Panel. Install the
Pole-Operated 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
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.
