Mounting Bracket
The Series EHG CL 
mounting bracket lets 
you mount the con-
troller in any of four 
angles. After discon-
necting both wiring 
connectors, gently 
rotate the controller 
counterclockwise until 
it unlocks from the 
mounting bracket. 
Re-orient the control-
ler on the mounting 
bracket and gently ro-
tate it clockwise until 
it locks.
