3. Installation
3.1 Mounting the Powershelf
The Powershelf is mounted into a standard 19” rack using M5 or M6 screws and cage
nuts. For systems larger than 4U (rack units) in height, multiple standard Powershelf
magazines are strapped together by four of 18x63mm strapping plates – two at the rear
that must remain in place, and two on the front that can be removed once the shelf is
secured in the rack. A minimum of 4 screws are required to secure the Powershelf into the
rack.
It is recommended to initially install the Powershelf into the rack without either the
MiniCSU-3 or the RT9 rectifiers in place.

Wiring for the standard Powershelf is rear access only. For systems where rear access is
not available, the Powershelf can be pre-wired for load, battery, AC power and remote
communications before mounting the magazine in the rack. For maintenance and load
expansion, the Powershelf is slid forward until the rear top cover is able to be opened to
access the wiring points with suitably insulated tools.
