INTENDED USERS
This Instruction Manual is to be made available to all persons who are required to configure, install or service the
equipment described in this manual or any other related activity.
ADDITIONAL INFORMATION
ATTENTION: The following information is provided merely as a guide for proper installation. Cleveland Motion
Controls cannot assume responsibility for the compliance (or failure to comply) to any code (national, local or other)
that prescribes the proper installation of this electro-mechanical device or associated equipment. A hazard of
personal injury and/or property damage can exist if applicable codes are not adhered to.
CE EMC RESPONSIBILITY
The Intrinsically Safe Barrier Block may be used by a manufacturer as a component of a larger system, along with
other components, which may or may not bear the CE mark. The system assembler is responsible for the
compliance of the system as a whole with the EMC Directive.
Before installing the Intrinsically Safe Barrier Block you must clearly understand who is legally responsible for
conformance with the EMC Directive. Misappropriation of the CE mark is a criminal offense.
INTRINSICALLY SAFE APPLICATION RESPONSIBILITY
The Cleveland-Kidder Classic Series Transducer may be used by a manufacturer as a component of a larger system,
along with other components, which may or may not be rated for Intrinsically Safe Applications. The system
assembler is responsible for the compliance of the system as a whole to any applicable Intrinsically Safe
specifications required.
The use of an approved Intrinsically Safe Barrier block with the Classic Series Transducers falls under the “Modular
Approach” or “Entity Concept” with the Classic Transducers being classified as a “Simple Device” or “Simple
apparatus” and the barrier block as the “Intrinsically Safe” or “associated apparatus”.

1 IMPORTANT INFORMATION
1.1 ORDER NUMBERS
There are two kits available depending on whether there is one transducer like the CLT type or two transducers in
the system.
The MO-13904-1 Barrier Block kit is for one transducer systems.
The MO-13904-2 Barrier Block kit is for two transducers systems.
1.2 CONTACT INFORMATION AND SERVICE ASSISTANCE
For service assistance, have the following information available:
• Type of Transducer you are using

1.3 RECEIVING AND UNPACKING
After receiving the Barrier Block Kit you should:
• Carefully, unpack and inspect the equipment
• Compare the received shipment with the packing list
• Report any damage to the carrier and your CMC representative
• Store equipment that will not be used in a clean, dry location
• Take appropriate precautions to prevent moisture, dust and dirt from accumulating in storage and
installation areas
1.4 EXCITATION VOLTAGE
Maximum Excitation Voltage for the Classic Series transducers when used with these Barrier Blocks must be limited
to 5.6 VDC or 5.6 VRMS. Do not use 10 Volt excitation or possible damage to the semiconductor strain gage
elements can occur. Before applying power to the amplifier, verify that the amplifier excitation voltage has been set to
5.0 VDC.

2 INSTALLATION
2.1 BEFORE INSTALLING THE BARRIER BLOCKS
Before installing the Barrier Blocks, perform the following steps:
1. Review the Installation manual for the amplifier or control system being used.
2. Review the Installation manual for the Cleveland-Kidder Transducers being used
3. Review the Installation manual part number INM7700 for the MTL 7700 Series Barrier Blocks.
2.1.1 INSTALLATION PRECAUTIONS
To ensure proper installation of the barrier blocks in an intrinsically safe application, all wiring instructions, safety
considerations and warnings must be followed in the MTL INM7700 Instruction Manual.
Failure to follow the MTL INM7700 Instruction Manual can result in a system that does not meet the
intrinsically safe specifications and could result in loss of lif e and property. Clev eland Motions Controls
cannot be held responsible for improper installation of the Barrier Blocks.
2.1.2 SAFETY CONSIDERATIONS
Safety practices should not be an afterthought. Before installing, servicing or calibrati ng review and follow
applicable policies and procedures to ensure worker safety. Machinery must be in a safe state and be aware of
any additional hazards that can arise when installing and calibrating Intrinsically Safe Systems.

2.2 MOUNTING THE BARRIER BLOCKS
The barrier blocks are attached to a Din Rail which is isolated from the main mounting surface by isolation blocks.
The isolation blocks are required per section 5.3 in the MTL INM7700 instruction manual.
Figure 1 –Mounting Diagram
2.3 ELECTRICAL CONNECTIONS AND WIRING
The intrinsically safe barrier blocks are connected to the Cleveland-Kidder Classic Series Tension Transducers and
control equipment or an Classic Din Rail Amplifier as shown in figure 2a for single transducers such as the CLT
style and figure 2b for dual transducers. There are additional wiring requirements for the IS barrier blocks such as
the Isolated Earth Ground that are described in more detail in the MTL INM7700 Instruction Manual that need to be
connected properly to ensure Intrinsically Safe compliance.
Also make certain that:
• The cables do not interfere with the web path, and that they are away from gearing or other moving
parts.
• You exercise care when routing the cables to avoid pick-up from noise-radiating power cabling (motor
armature leads, AC main wiring, etc).
• In environments with severe electromagnetic noise, it may be necessary to route the cables inside
metallic conduit.
