11Smart-UPS® VT and MGE™ Galaxy™ 3500 10-30 kVA 208 V MBP Installation
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.
Utility connections.
