Product Overview
The Schneider TM5ACLPR10 Right Bus Base Locking Plate is a mechanical accessory for the Modicon TM5 modular I/O system. It is installed on the right side of a TM5 bus base to cover exposed bus contacts at the end of a system configuration. The part is particularly relevant to modular PLC installations where electronic modules and bus bases are assembled in a row.
In a control cabinet, a TM5 system may contain a controller, bus bases, electronic I/O modules, and associated terminal blocks. When the assembly ends, the exposed bus contacts at the rightmost position need to be protected against accidental contact and potential electrostatic discharge. The TM5ACLPR10 provides the designated end-position plate for this purpose.
The locking plate is supplied in a package of 10 pieces under the TM5ACLPR10 reference. Its function is mechanical protection rather than electrical signal processing: it does not add I/O channels, establish a communication link, or change the operating parameters of the controller.
During panel assembly or module replacement, the correct end plate helps maintain the intended configuration of the TM5 bus system. It is especially important to distinguish the right-side TM5ACLPR10 from the left-side TM5ACLPL10, which serves the opposite end of the bus-base arrangement.

- Packaged spare parts: Supplied as a 10-piece accessory pack for assembly work and maintenance inventory.
Working Principle
The TM5ACLPR10 provides a physical barrier over the exposed contacts at the right end of the TM5 bus-base assembly. Its function is passive: it does not require electrical power, configuration software, or a control signal.
A typical arrangement is:
TM5 Controller / I/O Modules → Bus Bases → Rightmost Bus Base → TM5ACLPR10
In a modular PLC installation, adjacent bus bases form the electrical and communication path used by the connected modules. At the end of the configuration, the right-side locking plate helps protect the exposed contact area from accidental contact and electrostatic discharge during installation and handling.
The plate does not replace the bus base, terminal block, or electronic module. Each component has a separate mechanical or electrical function. The TM5ACLPR10 is fitted at the designated rightmost position, while the corresponding left-side plate, TM5ACLPL10, is used at the first slice of a remote configuration.
Correct placement matters because a plate intended for the opposite side should not be treated as an interchangeable substitute. During assembly, technicians should confirm the orientation of the bus-base row and ensure that the plate is properly seated before handling or commissioning the completed system.
Role in the Modicon TM5 System Architecture
The TM5ACLPR10 is a protective accessory located at the physical boundary of the modular I/O assembly. It supports the mechanical completion of the bus-base arrangement without changing the controller’s processing or I/O functions.
TM5 Controller → Bus Bases and Electronic Modules → Rightmost Bus Base → TM5ACLPR10

Installation and Maintenance
- Verify the part number: Confirm that the replacement is TM5ACLPR10 and not the left-side TM5ACLPL10.
- Identify the bus-base arrangement: Locate the rightmost bus base in the Modicon TM5 configuration before fitting the plate.
- Follow electrical safety procedures: Apply the required isolation and handling precautions before working on the controller assembly.
- Inspect the bus contacts: Check the exposed contact area for contamination, damage, or signs of electrostatic discharge.
- Check the mounting area: Inspect the right end of the bus base for obstructions or damage that could prevent correct seating.
- Confirm the plate orientation: Position the TM5ACLPR10 so that it matches the designated right-side installation.
- Fit the locking plate: Install the plate using the intended mounting arrangement without forcing it into position.
- Check the seating: Verify that the plate is properly engaged and covers the intended exposed contact area.
- Inspect adjacent modules: Ensure that the installation has not disturbed the neighboring bus base, electronic module, or terminal block.
- Review the completed assembly: Check that the rightmost end of the TM5 configuration is protected and that the other system components remain correctly installed.
- Replace damaged parts: If the plate is cracked, deformed, or unable to remain correctly seated, replace it rather than relying on an improvised cover.
- Record the maintenance: Document the replacement part number and inspect the remaining end plates during the same service operation.

Technical FAQs
Where should the TM5ACLPR10 be installed in a Modicon TM5 assembly?
Install it at the rightmost slice of the TM5 configuration to protect the exposed bus contacts. The leftmost position of a remote configuration uses the corresponding left-side plate, TM5ACLPL10.
What is the difference between TM5ACLPR10 and TM5ACLPL10?
The TM5ACLPR10 is the right bus base locking plate, while the TM5ACLPL10 is the left bus base locking plate. Their installation positions differ, so the two references should be selected according to the end of the assembly being protected.
Does the TM5ACLPR10 provide electrical isolation between TM5 modules?
No. It is a mechanical protective accessory, not an electrical isolator. It covers the designated exposed bus-contact area but does not provide galvanic isolation or change the electrical characteristics of the TM5 bus.
Why is the locking plate important during PLC installation?
Exposed bus contacts can be vulnerable to accidental contact and electrostatic discharge during assembly and handling. Installing the designated plate at the correct end helps protect the TM5 system and completes the intended end-of-row arrangement.
