2 DIMENSIONS AND INSTALLATION

Network, Power and Grounding:

A single 5 pin connector is used to make both a network connection and power input. A quality class 2
power supply should be used for this product. If the power is run with the network cable, care must be
taken such that the voltage does not drop below the lower supply limit on longer runs.

A quality earth ground is required for safe and proper operation. The best ground is achieved by
screwing the lower left grounding location into a grounded back plate. Alternately a ground can be
connected to the spade lug.

Please see Horner manual MAN0799 for details on CAN wiring.
