3.7 LP004A , DC-powered, -48VDC Installation

This section describes the proper connection of the -48VDC leads to the DC power terminal block on the LP004A hardened PoE (as shown in Figure ). The DC terminal block on the LP004A is located on the left side of the unit and is equipped with three (3) screw-down lead posts. The power terminals are identified as positive (+) and negative (-), and they are floating inside the unit so that either of the terminal may be grounded by the user if desired. The chassis is “earth” or ground (GND).

The connection procedure is straightforward. Simply insert the DC leads to the LP004A’s power terminals, positive (+) and negative (-) screws. The use of Ground (GND) optional; it connects to the LP004A chassis. Ensure that each lead is securely tightened from the top, as shown here.
