INSTALLATION GUIDE

NI PS-15/16/17 Side Mount Brackets

This document provides the installation procedure for the
NI PS-15/16/17 Side Mount Brackets. This accessory is used to mount
NI PS-15/16/17 power supplies sideways to reduce the installation depth.

Two side mounting options are possible:

• 35mm 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 A column
provides dimensions from the front of the power supply to the rearmost
mounting screw for the assembly of power supply and brackets. The
B column provides the total installation depth of the assembly when
mounted. The C column 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.

If the unit is panel mounted, the B dimension shows the required installation depth. If the unit is DIN-Rail mounted, the

total installation depth is the B dimension plus 6mm plus the height of the DIN-Rail.

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 B and C variables 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 B dimension plus 6mm plus the height of
the DIN-Rail. In case the unit is panel mounted, the B dimension 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.
