Wiring/Installation
•
Refer to the system installation guide and Lutron job
drawings for power cable and data cable (control
link) wiring restrictions and limitations.
•
Connect the wallstation to the control link inside the
wallstation’s wallbox or in a junction box (provided
by others).
• Use the wire connector required by local code.
•
Control link wiring must
not
be run in the same
raceway as line voltage.
•
The drain/shield wire must be maintained throughout
the control link. Do
not
connect the shield to earth/
ground or allow contact with the grounded wallbox.
• Do not connect high-voltage power to low-
voltage ter mi nals. Improper wiring can result in
personal injury or damage to the control or to other
equipment.
