3.2: Mounting the Nexus LED External Displays
The Nexus 1250/1252 LED Displays, Model # P40N, P41N and P43N, mount using a standard
ANSI C39.1 drill plan.
Secure the four mounting studs to the back of the panel with the supplied nuts.
Six feet of RS-485 communication/power cable harness is supplied. Allow for at least a 1.25-inch
(3.17cm) diameter hole in the back for the cable harness. See Chapter 5 for communication and
power supply details.
The cable harness brings power to the display from the Nexus 1250/1252 Meter, which supplies
15–20V DC. The P40N (or P41N or P43N) can draw up to 500 mA in display test mode.
