RS485 Wiring Overview

R

Installation of GRAFIK5000 / GRAFIK6000 / GRAFIK7000 System 11

Wiring Notes:

• Two #12 AWG (2.5 mm

2

) wires cannot fit into

most connectors on the RS485 link. Use a

screw on connector (or other approved

connector) to “T-tap” a #18 AWG (1.0 mm

2

)

wire to each connector terminal, as needed.

Make this “T-tap” in the Wallbox in order to

keep the length of the new #18 AWG (1.0

mm

2

) wire(s) as short as possible

• Connect the uninsulated Drain/Shield wire(s) to

terminal ‘D’ whenever present. If there is no

terminal ‘D’, connect the two Drain/Shield wires

together, making a continuous shield

throughout the link. If the connector at the end

of the link does not have a ‘D’ terminal,

terminate the shield and let it ‘float’

• Do not allow any part of the shield to touch

ground (earth) or any electrical circuitry

• CSDs are expected to mount into metal

Wallboxes that are connected to grounded

conduit. Grounding the metal mounting plate

helps keep Electrostatic Discharge (ESD) from

affecting the RS485 link
