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 p r i l 2 4 th, 2 0 2 0 P a g e 11 | 191
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.

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 EXL10 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 EXL10 OCS.
1. Remove all connectors from the EXL10 OCS unit.
2. Make sure the gasket is installed on the EXL10 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 EXL10 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 N-m).

3.4 Panel Cut-Out & Dimensions
For installations requiring NEMA 4X liquid and dust protection the panel cutout should be cut with a
tolerance of +1mm /-0mm..

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.)
2 (50.80mm)
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.
3.5.4 Orientation
When panel-mounted, there are no orientation restrictions on the EXL10 OCS.
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.
