• Use low-voltage Class 2 (PELV) wiring to daisy-chain
Wallstations to Control Units and other components.
• Make connections inside the wallbox or in a switch/junction
box with a maximum wire length of 8 feet (2.5m) from the link
to the Wallstation.
When used with GRAFIK Eye 3000 Control Units:
• Two #18 AWG (1.0mm
2
) conductors for common (terminal 1)
and 12 V Direct Current (terminal 2). Ensure that the terminal 2
connection is wired correctly. Refer to GRX-3000 Specification
Submittal for more details.
• One shielded, twisted pair #18 AWG (1.0mm
2
) for data link
(terminals 3 and 4).
When used with GRAFIK Eye 4000 Control Units:
• Two #12 AWG (2.5mm
2
) conductors for common (terminal 1)
and 24 V Direct Current (terminal 2).
• One shielded, twisted pair #18 AWG (1.0mm
2
) for data link
(terminals 3 and 4).
• Do not connect Drain/Shield to Ground (Earth) or Wallstation.
Connect the bare drain wires and cut off the outside shield.
