    2 Overview Meridian SL-1 systems (upgraded) capable of operating on Generic X11 Release 16, or later, software. An individual AEM can be placed in a column with other Meridian 1 modules in system options 21, 51, 61 or 71. This document explains how to install a stand-alone AEM and add an AEM to a Meridian 1 column.

  • Page 8: Stand-Alone Components

    Stand-alone components A stand-alone configuration consists of a pedestal, an AEM, and a top cap. Pedestal The pedestal houses a blower unit, an air filter, and the Power Distribution Unit (PDU). The PDU, which distributes power to the entire column, contains the field wiring terminal block, the main circuit breaker (or breakers) for the column, and a slot that houses the system monitor.
