RDA-ENC6B and ENC12B 
Dimmer Enclosures w/Breakers
The RDA-ENC6B (FG606-13) and RDA-ENC12B (FG606-14) enclosures 
provide secure mounting for all AMX Lighting and ProLink controllers, and 
lighting modules. These enclosures contain circuit breakers. 
These enclosures are CE, UL, and C-UL approved. They include circuit breakers 
and terminals for multi-phase wiring. 
They also provide 18 knockouts for 1/2", 3/4", and 1" conduits.              
Installation Instructions:
• For indoor use only.
• Mount on vertical surface only.
• Maintain 12" (304.88 mm) minimum clearance above and below the enclo-
sure.
• Route class 1 conductors through upper conduit knockouts.
• Route class 2 conductors through lower conduit knockouts.
• Use 75°C (167°F) copper conductors only.
• Install filler plate #28-10500 (RDA-EFP) in all unused openings.
• Install only UL approved modules (see the UL Number Cross 
Reference to AMX Lighting ID table on page 2).
