NOTE: Refer to the datasheet for X4 [MAN1138] via the Document Search for more details. For the Voltage Units,
refer to MAN1409 for the HE-X4R-V20 or MAN1410 for the HE-X4R-42.
Mounting Overview
The mechanical installation greatly affects the operation, safety, and appearance of the system. Information is
provided to mechanically install the unit such as cut-out sizes, mounting procedures, and other recommendations
for the proper mechanical installation of the unit.
Mounting Procedures (Installed in a Panel Door)
Once the panel design has been completed using the criteria and suggestions in the following sections, use the fol-
lowing steps to panel mount the X4 OCS.
NOTE: Unit comes with composite clips, which are tested for typical wash down, shock, and vibration. If metal
mounting clips are needed, they can be ordered at the Horner Automation website.
1. Carefully locate an appropriate place to mount the X4. Be sure to leave enough room at the top of the unit for
insertion. Remove the microSD card to prevent damage to the panel edge.
2. Carefully cut the host panel per the measurements found in the datasheet MAN1131. Dimensions can also
be found below in the Panel Cutout section. If the opening is too large, water may leak into the enclosure,
potentially damaging the unit. If the opening is too small, the OCS may not fit through the hole without dam-
age. NOTE:For the Voltage Units, refer to MAN1409 for the HE-X4R-V20 or MAN1410 for the HE-X4R-42.
3. Remove any burrs and/or shape edges and ensure the panel is not warped in the cutting process.
4. Make sure the gasket is installed on the X4 OCS and is free from dust and debris. Check that the corners of
the gasket are secure.
5. Pass the unit through the panel.
6. Insert each of the four (4) mounting clips into the slots in the X4 OCS case. One composite plastic clip should
be installed on each corner. Lightly tighten each screw so the clip is held in place.
Clip Description Part Number
Composite Plastic Clip 400B178-R2.0
Metal Clip HE500ACC604
7. Tighten the screws on the clips such that the gasket is compressed against the panel. Recommended torque
is 2-3 in-lbs (0.23 – 0.34 Nm). If metal mounting clips are used in place of the plastic composite mounting
clips, the recommended torque is 4-8 in-lbs (0.45-0.90 Nm).
8. Connect communications cables to the serial port, USB ports, and CAN port as required.
