APC 3500 manual Making external cable connections

Making external cable connections

Note: Utility cables can enter through the top or the bottom of the MBP. However, BOTTOM is recommended.

External cables can enter the MBP through any of the available 1-inch [25.4mm] knockouts, or by making larger cutouts in the top or bottom plates of the enclosure. Each plate offers 22 knockouts and the ability to create up to four (4) 2-inch [50.8mm] cutouts.

Prior to making any of the following external cable connections, establish an appropriate point of access by knocking out a 1-inch hole or cutting a larger hole in the top or bottom plate. The plate can be removed using a Phillips screwdriver to loosen the 12 screws securing it to the enclosure. An M10 nut driver is needed to remove the M6 flange nut securing the ground cable to the plate’s ground stud.

The cables are typically color coded: L1 = black, L2 = red, L3 = blue, N = white, and G = green.
