Installation and Wiring

Wiring length guidelines

The Master requires a 12 VDC power from a PSN to operate properly. The unit should only have one source of incoming power.

Using more than one source of power to the Master can result in damage to the internal components and a possible burn out.

An auxiliary 12 VDC power supply can provide power to the Master. Refer to the following table for wiring length information:

Wiring a 2-pin power connection

To use the NetLinx 2-pin 3.5 mm mini-Phoenix power supply jack for power transfer from the PSN power supply to the rear of the NXC-ME260, the incoming PWR and GND cables from the PSN must be connected to its corresponding location on the 2-pin 3.5 mm mini-Phoenix connector (FIG. 5).
