INSTALLATION GUIDE
NI PS-14/15/16/17 Side Mount
Brackets
This document provides the installation procedure for the NI PS-14/15/16/17 Side Mount
Brackets. This accessory is used to mount NI PS-14/15/16/17 power supplies sideways to reduce
the installation depth.
Two side mounting options are possible:
• 35 mm DIN-Rail Mount
• Panel Mount
Bracket and Assembly Dimensions
This section provides bracket and assembly dimensions. Table 1 provides a summary of the
dimensions and weight of the overall assembly when a specific bracket set is mounted to a
specific power supply. The Unit column lists the available power supplies. The Bracket Set
column indicates the appropriate brackets to use with the specified power supply. The Acolumn
provides dimensions from the front of the power supply to the rearmost mounting screw for the
assembly of power supply and brackets. The Bcolumn provides the total installation depth of
the assembly when mounted. The Ccolumn provides the depth of the power supply only. The
Length column provides the total length of the assembly. The Width column provides the width
of the mounting brackets. The Height column provides the height of the brackets only. The
Bracket Set Weight column provides the weight of the bracket set only.

Figure 1, Figure 2, and Figure 3 show the brackets for DIN-Rail mounting.
Figure 1 provides the layout of a mounting bracket in three physical dimensions, to allow easier
visualization when using Table 1 with Figure 2 and Figure 3 to determine the dimensions of a
specified bracket set mounted to a specified power supply.
Figure 1. Physical Dimension Variables
Figure 2 provides the Band Cvariables for determining the depth of a bracketed power supply
assembly when mounting the assembly to a DIN-Rail or panel.
The total installation depth is the Bdimension plus 6mm plus the height of the DIN-Rail. In case
the unit is panel mounted, the Bdimension shows the required installation depth. The C
dimension is the depth of the power supply itself, and its sum is included in the value of B.
All measurements are in millimeters.
