2.1.1. Power Connection
WARNING! Before you start the installation, check if the Power Supply provides the
specified output voltage, i.e. 24Vdc +/- 10%/0.5A.
For power connection use the 4.2mm Mini-Fit Jr receptacle (LS PN 350238) and the
female crimp terminals for AWG18-24 (LS PN 350238). Strip the wire isolation 3.0-3.5 mm
and crimp the terminals on the wire using the Molex crimping tool 11-01-0197. Insert the
terminals in the receptacle body – terminals 1 for (+24V), terminal 3 for (GND) voltage and
terminal 2 (middle) for the ground.
Remove the connectors cover (Figure 3) and plug in the power connector into the Power
In jack. The Power LED (green) goes ON and the Data LED (red) blinks three times
(booting). After booting, PRX23 is ready to receive over the air tag messages.
