INJ-24 Series Quick Installation Guide Moxa PoE Injector Edition 4.0, February 2017 Technical Support Contact Information www.moxa.
Overview The Moxa PoE Injector INJ-24 Series is a 1-port PoE injector that delivers both data and electrical power to Ethernet-enabled devices using a single Ethernet cable. The INJ-24 can supply up to 30 watts of power through the Ethernet port, and can power IEEE 802.3af/at compliant powered devices (PD), such as wireless access points or IP cameras, eliminating the need for additional wiring. The INJ-24 supports Gigabit communication, which is vital for high-speed and low-latency applications.
WARNING Safety First! Be sure to disconnect the power cord before installing and/or wiring your Moxa PoE injector. Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes dictating the maximum current allowable for each wire size. If the current goes above the maximum ratings, the wiring could overheat, causing serious damage to your equipment.

Mounting Dimensions (unit = mm) DIN-Rail Mounting The plastic DIN-Rail attachment plate should already be fixed to the back panel of INJ-24 when you take it out of the box. If you need to reattach the DIN-Rail attachment plate, make sure the stiff metal spring is situated towards the top, as shown in the figures below. STEP 1: Insert the top of the DIN-Rail into the slot. STEP 2: The DIN-Rail attachment unit will snap into place as shown below.
To remove the INJ-24 from the DIN-Rail, insert a flat-blade screw driver horizontally into the DIN-Rail kit under the INJ-24, and then pull it upwards and release INJ-24 towards you away from the DIN-Rail. You may also take the following steps to remove the INJ-24 from the DIN-Rail. Step 1: Step 2: Press the middle of the flat side of Release it towards you and away the mounting kit as indicated. Pull from the DIN-Rail. the INJ-24 downwards.
Wiring the INJ-24’s Power Outputs The two left-most contacts of the 3-contact terminal block connector on the INJ-24’s top panel are used for 24 VDC output. Top and front views of one of the terminal block connectors are shown here. STEP 1: Insert the negative/positive DC wires into the V-/V+ terminals. STEP 2: To keep the DC wires from pulling loose, use a small flat-blade screwdriver to tighten the wire-clamp screws on the front of the terminal block connector.
