CHAPTER 1: SAFETY / 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.

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.
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.

Check that the corners of the gasket are secure.
2. Pass the unit through the panel.
3. Insert each of the four (4) mounting clips into the slots in the XL7/XL7 PRIME OCS case. One clip
should be installed on each corner. Lightly tighten each screw so the clip is held in place.
