Flush Mounting the LTMCU

Overview

This section describes how to mount the LTMCU inside a panel cut-out, as well as the accessories needed for mounting.

LTMCU Rear Face

The various elements of the rear face of the LTMCU are shown in the diagram below:

1 Mounting fixation (with mounting nut)

2 Clamp

3 Rear RJ45 port

Panel Setup Procedure

Stage	Description
1	Check that the installation panel or cabinet’s surface is flat, in good condition, and has no jagged edges. Metal reinforcing strips can be attached to the inside of the panel, near the panel opening, to increase the panel’s rigidity.
2	Panel thickness should be from 0.8 to 6 mm (0.03 to 0.23 in.).
3	Verify that the ambient operation temperature and the ambient humidity are within their designated ranges. (When installing the LTMCU in a cabinet or enclosure, the ambient operation temperature is the cabinet or enclosure’s internal temperature.)
4	Verify that heat from surrounding equipment does not cause the LTMCU to exceed its standard operating temperature.
5	When installing the LTMCU in a slanted panel, the panel face should not incline more than 30°. When installing the LTMCU in a slanted panel, and the panel face inclines more than 30°, the ambient temperature must not exceed 40°C (104°F).

Mounting the LTMCU

Step	Action
1	Cut an opening of 45 x 92 mm (1.77 x 3.6 in.) into the panel.
2	Insert the unit into the panel cut, as shown below:
3	As shown below, position the metallic washer only if the panel thickness is more than 3.5 mm (0.14 in.). Position the clamp in place, then insert the mounting nut and tighten. If the mounting nut is not correctly attached, the unit may shift or fall out of the panel: To open and lock the mounting nut, use the special tool No. ZB5 AZ905, if needed.

Step

Action

Cut an opening of 45 x 92 mm (1.77 x 3.6 in.) into the panel.

Insert the unit into the panel cut, as shown below:

As shown below, position the metallic washer only if the panel thickness is more than 3.5 mm (0.14 in.).

Position the clamp in place, then insert the mounting nut and tighten. If the mounting nut is not correctly attached, the unit may shift or fall out of the panel:

To open and lock the mounting nut, use the special tool No. ZB5 AZ905, if needed.
