Take the overall dimensions of 6.63" [168.5] x 7.12" [181] x 2" [50.8] and mount in the interior of the RTU in a convenient location that you can access. Secure the ZIP utilizing #8 self-tapping screws (included). A minumum of two tabs need to be secured, one which is a top tab. Ideally secure all four tabs. Wire the electrical connection using ¼” female insulated spade connectors to prevent corrosion.
