2.1. EX23G Connections
Power Connections
WARNING Before you start the installation, check if the Power Supply provides the specified
output voltage – 22Vac +/- 10% or 25.2-30.8Vdc, and min. 0.5A; any polarity can be used for the
dc output. For the power connections 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 and 3 for ac voltage and terminal 2 (middle) for the ground.
Plug in the power connector into any of the corresponding headers on the EX23G. The POWER
LED (green) goes ON.
RS485 Connections
For the RS485 connection use a standard Cat5 Ethernet cable and RJ45 plug. Crimp the connector
using the recommended tool and the following color scheme: pin 1 - Wh/Or; pin 2 – Or; pin 3 –
Wh/Gr; pin 4 – Bl; pin 5 – Wh/Bl; pin 6 – Gr; pin 7 – Wh /Br; pin 8 – Br.
