If your lighting system has multiple control units, connect them using PELV (Class 2: USA) cabling as described here.
Daisy-chain the PELV (Class 2: USA) cabling to terminal 1, terminal 2, terminal 3, and terminal 4 on all control units
and wallstations.
WARNING! Make sure no bare wire is exposed after making connections. The recommended installation
torque is 3.5 in.-lbs. (0.4 N•m) for PELV (Class 2: USA) connections.

Special Mounting Considerations

Wallbox Mounting and Spacing
When mounting multiple control units or interface devices, be sure to follow spacing requirements to ensure proper
operation.
• All control units MUST be mounted in a standard U.S. wallbox. (For
mounting procedures, refer to page 7.)
• Allow 1 in. (25 mm) for faceplate overhang on all sides.
