Communication and Power.
• T15 Pin in Torx Driver is required (Not Supplied)
• Take care not to lose screws.
• See: Back View Cover Removed
4.
Choose the ½ inch trade knockout to remove for your
installation location. Two are provided. No other entry
holes may be added to the sign or warranty will be
voided.
• Wire, conduit, conduit fittings for making connections
to rear of LED sign are not supplied.
• Use appropriate conduit fittings and connections to
route wires for power and communication into the
LED sign termination compartment.
5.
Wiring method shall be in accordance with:
• In Canada, CSA C22.1, Canadian Electrical Code,
Part I, Safety Standard for Electrical Installations,
Section 32;
• In the United States, the National Electrical Code,
NFPA 70, and the National Fire Alarm and signaling
Code, NFPA 72;
6.
Make the minimum customer connections to the sign.
• Nominal 24VDC connects to V-in (+) Positive and V-in
(-) Negative/Ground terminals of sign. (Positive to V-
in (+) and Negative/Ground to V-in (-) Negative/
Ground).
For the 24VDC connection a wire
gauge of 28AWG (minimum) to 12AWG
(maximum) is required; torque 24VDC
connection terminal points to a maximum of 7
lb-in.
• Attach the provided ferrite around the nominal 24VDC
Positive and Negative/Ground wiring (ferrite must be
attached within the sign).
• Chassis terminal on sign to be connected to earth
ground.
• RS485 connection:
• Shielded RS485 cable recommended. Connect
shield of cable to SHLD terminal of sign and to
chassis ground of transmitting device.
• RS 485 connection to D+ and D- terminals of sign.
• If the RS485 signal from the transmitting device is isolated, then connect GND terminal of sign to the signal
ground terminal the transmitting device.
• If the RS485 signal from the transmitting device is not isolated, the GND terminal of the sign can be left open.
• Termination of the RS485 signal is to be determined per the application. If termination is used at the transmitting
device, connect a jumper between the TERM and D- terminals on the sign.
•
For the RS485 connection a wire gauge of 28AWG (minimum) to 18AWG (maximum) is required;
torque RS485 connection terminal points to a maximum of 5 lb-in.
7. Replace the removable cover using the 4 - 6-32 tamper proof screws
• T15 Pin in Torx Driver is required. (Not Supplied)
• Torque to a maximum of 10 lb-in.
