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.
MAN0974-09-EN_XL7_UserManual

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.

3.1 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.
3.2 Mounting Requirements
3.2.1 Mounting Procedures (Installed in a Panel Door)
Figure 3.1 –Panel Mounting of an XL7 Series OCS
MAN0974-09-EN_XL7_UserManual
March 4th, 2019 Page 17 | 185
Once the panel design has been completed using the criteria and suggestions in the following
sections, use the following steps to panel mount the XL7 OCS.
1. Remove all connectors from the XL7 OCS unit.
2. Make sure the gasket is installed on the XL7 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 four (4) mounting clips into the slots in the XL7 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 7-10 in-lbs (0.8-1.13 Nm).

3.5 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
.
3.5.1 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.)

3.5.2 Grounding
Panel box: The panel box must 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.
3.5.3 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 meet
applicable electrical codes and standards.
