About the Drive and Cabinet

This chapter describes how to identify the Trane cabinet and the Liqui-Flo drive using
the Trane model number matrix. Liqui-Flo drive power ratings are listed as well as
available Trane options. Cabinet component drawings are also provided. Note that in
this manual references to the “cabinet” refer to both the 6-pulse and 12-pulse rectifier
cabinets, unless otherwise indicated.

2.1 Identif ying the Tran e Model Number

Each Trane cabinet can be identified by its model number. See figure 2.1. A typical
cabinet model number is shown in table 2.1 as are the Liqui-Flo drive power ratings.

2.2 Enclosure Rating

The Trane cabinet has a NEMA 1 enclosure rating:

•

NEMA 1: Vented. Intended for general-purpose indoor applications.

NEMA 1 enclosures are to be located in a clean and dry environment that is away
from oil, coolant, or other airborne contaminants.

2.3 Identifying Trane Cabinet Components

The 6-pulse rectifier Trane cabinets have the following main components. The
identification numbers provided correspond to the numbers used in figure 2.2.
