Once the panel design has been completed using the criteria and suggestions in the following
sections, use the following steps to panel mount the XLE/XLT.
1. Remove all connectors from the XLE/XLT unit.
2. Press the DIN rail clip up to make passing the unit through the cutout easier.
3. Make sure the gasket is installed on the XLE/XLT and is free from dust and debris. Check that
the corners of the gasket are secure.
4. Pass the unit through the panel.
5. Insert the each of the four (4) mounting clips into the slots in the XLE/XLT case. One clip
should be installed on each corner. Lightly tignten each screw so the clip is held in place.
6. Tighten the screws on the clips such that the gasket is compressed against the panel.
Recommended torque is 7-10 in-lbs [0.8-1.13 Nm]).
3.2.2 Mounting Procedures (Installed on DIN Rail)
Figure 3.2 –DIN Rail Mounting of the XLE/XLT
The XLE/XLT is designed to clip onto standard 35mm DIN rail. If your installation requires
liquid or dust protection, make sure the XLE/XLT is placed in an appropriate sealed panel
when mounting on DIN rail. Use the following steps to mount the XLE/XLT on DIN rail.
1. Move the DIN rail clip to the lower position.
2. Clip the “Top Clips” on the top of the DIN rail.
3. Press the unit into place and press the DIN rail clip up. A small flat-head screwdriver
can be used in the slot of the DIN rail clip if clearance is an issue.
NOTE: The DIN rail connection does not provide an earth ground. Refer to Page 20 for proper
grounding information.

3.4 Panel Cut-Out
For installations requiring NEMA4X liquid and dust protection the panel cutout should be cut
with a tolerance of +/- 0.005” (0.1 mm). The XLE/XLT is designed to fit 1
4DIN panel openings.
There are a number of punches and enclosures designed to accommodate opening of this size.

3.6 Factors Affecting Panel Layout Design and Clearances
The designer of a panel layout must assess the requirements of a particular system and to
consider the following design factors. A convenient checklist is provided in Section 3.6.7.
3.6.1 Clearance / Adequate Space
Install devices to allow sufficient clearance to open and close the panel door.
Table 3.1 –Minimum Clearance Requirements for Panel Box and Door
Minimum Distance between base
of device and sides of cabinet
2”(50.80mm)
Minimum Distance between base
of device and wiring ducts
1.5” (38.10mm)
If more than one device installed in panel box
(or on door):
Minimum Distance between bases of each device
4”(101.60mm) between bases of each device
When door is closed:
Minimum distance between device and closed door
(Be sure to allow enough depth for XLE/XLT.)
2”(50.80mm)
3.6.2 Grounding
Panel box: The panel box must be properly connected to earth ground to provide a good
common ground reference.
Panel door: Tie a low impedance ground strap between the panel box and the panel door
to ensure that they have the same ground reference.
3.6.3 Temperature / Ventilation
Ensure that the panel layout design allows for adequate ventilation and maintains the
specified ambient temperature range. Consider the impact on the design of the panel
layout if operating at the extreme ends of the ambient temperature range. For
example, if it is determined that a cooling device is required, allow adequate space and
clearances for the device in the panel box or on the panel door.
WARNING: It is important to follow the requirements of the panel manufacturer and to follow all
applicable electrical codes and standards.
WARNING: Be sure to meet the ground requirements of the panel manufacturer and also meet
applicable electrical codes and standards.
