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.

Assembly and Mounting Instructions

This section provides instructions for mounting the power supply sideways to a panel or to a DIN-Rail.

Note The two aluminum brackets and the black plastic slide must be removed from the

units to allow mounting of the zinc-plated steel brackets.

Sideways Panel Mounting

Complete the following steps to mount the brackets to a flat wall.

1. Detach the two aluminium brackets by removing the four screws with a Torx 10 screwdriver, as shown in Figure 4.

DIN-Rail Mounting

Complete the following steps to mount the brackets to a DIN-Rail.

1. Install the mounting plate with the steps described in the Sideways

Panel Mounting section. When those steps are completed, the

mounting plate should be attached to the power supply as shown in Figure 7.
