Step 7:
The 14 AWG (2.5mm
2
) ground wire can terminate in one of three ways:
• Connected between stations using Scotchlok™ connectors (3M® #314
insulation displacement connectors, ETC part number J4166).
• Grounded to metal conduit.
• If grounded metal conduit is not installed, connect the 14 AWG (green)
ground wire to the DRd rack ground bus (the same as loads are grounded
to) inside the DRd rack, and to the green/yellow striped wire connected to
the control station using a Scotchlok connector. Reference the related
station installation manual for details.
Step 8:
Replace the connector to the right I/O board.
UL 924 Listed Panic Input
Termination is available for a UL 924 Listed dry contact input for
control bypass. The two pin panic connector, labeled “PANIC”,
accepts 16 AWG (1.5mm
2
) wire.
Step 1:
Pull panic wiring into the DRd rack through the conduit
opening previously prepared.
Step 2:
Strip 3/16” (5mm) of insulation from the ends of each
wire.
Step 3:
Remove the 2 pin Panic connector from the right I/O board.
Step 4:
Loosen the terminal screws.
Step 5:
Insert each wire into the terminals on the connector and tighten the screws firmly
to secure the wires into the connector.
Replace the connector to the right I/O board.
DMX Control Wiring
DMX wire preparation and termination will vary with the type of wire and termination kit
being utilized. Please refer to the instructions supplied with the DMX termination kit for
specific wire preparation.
DMX Input Wire Termination using the Screw Terminals
Connector
The graphic to the left illustrates DMX termination layout for the
screw-terminal connectors that are intended for use with Belden
9729 cable (or approved equal) cable type.
Screw terminal connectors are supplied as standard in the DMX
Preparation Kit w/ Screw Connector, part number 4100A1012.
Be aware that cable other than Belden 9729 may have a different
color code for its wire pairs.
