INSTALLATION
CAS-304 / CAS-308
1) Make sure the expansion screws of mounting brackets can filmy support the product weight
before installation to avoid causing the injuries of the facilities and a worker if there is a falling.
2) Make sure the bracket is installed in vertical position and install expansion screw in the identified
location.
3) Lock the bracket (in attached) to the wall enough tightly and ensure it’ s vertical between bracket
and wall.
4) Remove the 6*M8 screws on back of column and fix it to the racket via the screws( in attached).
Please make the column straight and firmly locked.
5) Adjust the column to appropriate angle with bracket adjustable angle vertical 0 °~ 30 °, horizon
-90 ° ~ 90 °.
6) Please first confirm the system you connected output of 100V, 70V. And make the cables con-
nected.
