3.6 Installation Procedure
• The XL4 utilizes a clip installation method to ensure a robust and watertight seal to the
enclosure. Please follow the steps below for the proper installation and operation of
the unit.
• This equipment is suitable for Class I, Division 2, Groups A, B, C and D or non-
hazardous locations only.
• Digital outputs shall be supplied from the same source as the operator control station.
• Jumpers on connector JP1 shall not be removed or replaced while the circuit is live
unless the area is known to be free of ignitable concentrations of flammable gases or
vapors.
1. Carefully locate an appropriate place to mount the XL4. Be sure to leave enough room
at the top of the unit for insertion and removal of the microSD™ card.
2. Carefully cut the host panel per the diagram, creating a 92mm x 92mm +/-0.1mm
opening into which the XL4 may be installed. 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 damage.
3. Remove any burrs and or sharp edges and ensure the panel is not warped in the
cutting process.
4. Remove all Removable Terminals from the XL4. Insert the XL4 through the panel
cutout (from the front). The gasket must be between the host panel and the XL4.
5. Install and tighten the four mounting clips (provided in the box) until the gasket forms
a tight seal NOTE: Max torque is 0.8 to 1.13Nm, 7 to 10 in-lbs.
6. Reinstall the XL4 I/O Removable Terminal Blocks. Connect communications cables to
the serial port, USB ports, Ethernet port, and CAN port as required.
