CHAPTER 1: SAFETY/ COMPLIANCE
1.1 Safety Warnings and Guidelines
When found on the product, the following symbols specify:
a. All applicable codes and standards need to be followed in the installation of this product.
b. For I/O wiring (discrete), use the following wire type or equivalent: Belden 9918, 18 AWG
or larger.
Warning: Consult user documentation.
Warning: Electrical Shock Hazard.
WARNING: EXPLOSION HAZARD –Do not disconnect equipment unless power has been
switched off or the area is known to be non-hazardous.
WARNING: To avoid the risk of electric shock or burns, always connect the safety (or earth)
ground before making any other connections.
WARNING: To reduce the risk of fire, electrical shock, or physical injury it is strongly
recommended to fuse the voltage measurement inputs. Be sure to locate fuses as close to the
source as possible.
WARNING: Replace fuse with the same type and rating to provide protection against risk of fire
and shock hazards.
WARNING: In the event of repeated failure, do not replace the fuse again as a repeated failure
indicates a defective condition that will not clear by replacing the fuse.
WARNING: EXPLOSION HAZARD –Substitution of components may impair suitability for Class
I, Division 2.
WARNING: The USB parts are for operational maintenance only. Do not leave permanently
connected unless area is known to be non-hazardous.
WARNING: EXPLOSION HAZARD - BATTERIES MUST ONLY BE CHANGED IN AN AREA KNOWN
TO BE NON-HAZARDOUS.
WARNING: Battery May Explode If Mistreated. Do Not Recharge, Disassemble or Dispose Of In
Fire.
WARNING: Only qualified electrical personnel familiar with the construction and operation of
this equipment and the hazards involved should install, adjust, operate, or service this
equipment. Read and understand this manual and other applicable manuals in their entirety
before proceeding. Failure to observe this precaution could result in severe bodily injury or
loss of life.

MAN0964-13-EN_XL4_UM
A u g u s t 6 , 2 0 2 1 P a g e 11 | 194
Adhere to the following safety precautions whenever any type of connection is made to the
module.
a. Connect the green safety (earth) ground first before making any other connections.
b. When connecting to electric circuits or pulse-initiating equipment, open their related
breakers. Do not make connections to live power lines.
c. Make connections to the module first; then connect to the circuit to be monitored.
d. Route power wires in a safe manner in accordance with good practice and local codes.
e. Wear proper personal protective equipment including safety glasses and insulated
gloves when making connections to power circuits.
f. Ensure hands, shoes, and floor are dry before making any connection to a power line.
g. Make sure the unit is turned OFF before making connection to terminals. Make sure all
circuits are de-energized before making connections.
h. Before each use, inspect all cables for breaks or cracks in the insulation. Replace
immediately if defective.
1.2 Grounding

mounting procedures, and other recommendations for the proper mechanical installation of
the unit.
3.2 Mounting Requirements
3.2.1 Mounting Procedures (Installed in a Panel Door)
Figure 3.1 –Panel Mounting of an XL4 Series OCS
Once the panel design has been completed using the criteria and suggestions in the following
sections, use the following steps to panel mount the XL4 OCS.
1. Remove all connectors from the XL4 OCS unit.
2. Make sure the gasket is installed on the XL4 OCS and is free from dust and
debris. Check that the corners of the gasket are secure.
3. Pass the unit through the panel.
4. Insert the each of the four (4) mounting clips into the slots in the XL4 OCS
case. One clip should be installed on each corner. Lightly tighten each screw
so the clip is held in place.
5. Tighten the screws on the clips such that the gasket is compressed against
the panel. Recommended torque is 4-8 in-lbs (0.45 –0.90 N-m).

CAUTION—For DIN Rail mounting:
To prevent the unit from slipping off the DIN Rail, do
not install the unit on its sides as shown. Be sure the
DIN Rail is in the horizontal position.
NOTE—For panel or DIN rail mounting:
The orientation shown above provides
for optimum readability of the screen

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.

3.7 Factors Affecting Panel Layout Design and Clearances
The designer of a panel layout needs to assess the requirements of a particular system and to
consider the following design factors
.
3.7.1 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 the OCS.)
2” (50.80mm)
3.7.2 Grounding
Panel Box: The panel box needs to 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.
3.7.3 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.
