CHAPTER 1: SAFETY AND COMPLIANCE
1.1: Safety Warnings and Guidelines
When found on the product, the following symbols specify:
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.

MAN1256-05-EN_EXLW_XLWP_UM
November 10, 2021 11 | 201
All applicable codes and standards need to be followed in the installation of this product.
For I/O wiring (discrete), use the following wire type or equivalent: Belden 9918, 18 AWG or
larger.
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 floors 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.

2.1 Visual Overview of EXLW/XLW PRIME
Figure 2.1 –Overview of the EXLW/XLW PRIME
NOTE: Use caution when connecting controllers to PCs via serial or USB. PCs, especially
laptops may use “floating power supplies” that are ungrounded. This could cause a damaging
voltage potential between the laptop and controller. Ensure the controller and laptop are
grounded for maximum protection. Consider using a USB isolator due to voltage potential
differences as a preventative measure.

Once the panel design has been completed using the criteria and suggestions in the following
sections, use the following steps to panel mount the EXLW/XLW PRIME OCS.
1. Remove all connectors from the EXLW/XLW PRIME OCS unit.
2. Make sure the gasket is installed on the EXLW/XLW PRIME 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 each of the ten (10) mounting clips into the slots in the EXLW/XLW PRIME 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).
