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.

MAN1032-10-EN_EXL6_UserManual
March 12, 2020 11 | 191
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.

CHAPTER 2: INTRODUCTION
2.1 Visual Overview of EXL6
Figure 2.1 –Overview of the EXL6
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.

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.

Once the panel design has been completed using the criteria and suggestions in the following
sections, use the following steps to panel mount the EXL6 OCS.
1. Remove all connectors from the EXL6 OCS unit.
2. Make sure the gasket is installed on the EXL6 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 EXL6 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).

NOTE: There are no orientation restrictions on the EXL6 OCS. However, the above orientation
provides for optimum readability of the screen and ease of use of the keypad.
3.4 Panel Cut-Out
For installations requiring NEMA 4X liquid and dust protection, the panel cutout should be cut
with a tolerance of + 1mm / -0mm.
