Meter Installation 4.1 Mounting STEP 1: Using the appropriate sized mounting hardware, fasten the Class 1000 meter enclosure to the selected mounting surface. The four mounting holes are centered 6.75” H x 4” W. The mounting hole spacing is identical for either the NEMA 12 or NEMA 4X enclosure. - Page 8 Meter Installation (Continued) 4.2 Main Power Board Connections (Continued) STEP 3: Wire Entry (continued) Outdoor applications require the use of the optional NEMA 4X enclosure. The same principles outlined for indoor meter installations as defi ned in the aforementioned paragraph carry over and apply to outdoor installations with one exception.
