Installation and Wiring

Wiring Devices to the AXB-232++

Preparing captive wires

To connect the wiring into a captive-wire connector:

1.Strip 1/4 inch off the wire insulation for all four wires.

2.Tin 2/3 of the exposed wire.

3.Insert each wire into the appropriate captive-wire connector up to the insulation.

4.Tighten the captive screws to secure the fit in the connector.

If the device is using a separate power supply, do not connect the power wiring from the AXB-232++ to that device.

Wiring guidelines

The interface requires a 12 VDC power to operate properly. The interface uses a PSN2.8 power supply. The Central Controller supplies power via the AXlink cable or external 12 VDC power supply. The maximum wiring distance between the Central Controller and interface is determined by power consumption, supplied voltage, and the wire gauge used for the cable. The table below lists wire sizes and maximum lengths allowable between the AXB-RS232++ and Central Controller. The maximum wiring lengths for using AXlink power are based on a minimum of 13.5 volts available at the Central Controller’s power supply.

Wiring Guidelines at 160 mA

Wire Size	Maximum Wiring Length
18 AWG	733.57 feet (223.59 m)
20 AWG	464.11 feet (141.46 m)
22 AWG	289.35 feet (88.19 m)
24 AWG	182.39 feet (55.59 m)
