Installing Racks

Introduction

When mounting TSX RKY •• racks, certain installation rules must to be followed.

Rack Installation Rules: Description

1 As the different modules (e.g. supply, processors, discrete I/O, etc.) are cooled by natural convection, it is compulsory in order to facilitate ventilation to install the different racks horizontally and vertically.
2 If several racks are installed in the same cabinet, you are advised to comply with the following advice on layout:
- leave at least 150 mm between two racks placed on top of each other, to allow room for cable troughs and help air circulation.
- you are advised to install the devices which generate heat (eg transformers, process supply, power contacts, etc.) above the racks,
- leave at least 100 mm on each side of a rack to allow room for cabling and to help air circulation.

NOTE: If the hardware, other than the metal electrical cabinet, is installed in an area with emissions limits between 30 MHz and 1GHz (as per EN 55022), you are advised to use racks TSXRKY 8EX or TSXRKY6EX instead of TSXRKY8 and TSXRKY6.
