Wiring and Connection Guidelines

General Guidelines:

• The controller must be protected against overload (see performance data).
• To prevent hardware damage, use a ramp function for control.
• Full-bridge motor outputs may only be connected to each other.
• Half-bridge outputs must not be connected in parallel.

CAN / LIN Bus Communication:

CAN/LIN bus communication is the primary communication between the control unit and the vehicle. Connect the CAN/LIN bus with particular care and verify correct communication with the vehicle to avoid unintended behavior.

Safety and Installation Instructions

General Safety:

• WARNING! Risk of system malfunction. Ensure the module is equipped with the correct software and that the hardware configuration and parameterization are appropriate.
• WARNING! Risk of unprotected moving components. Always switch off and secure the entire system before performing any work. Ensure the system and its components are in a safe state before starting commissioning.
• Never connect or disconnect the module under load or voltage.
• CAUTION! Risk of burns from housing. The housing may reach elevated temperatures. Do not touch the housing and allow all system components to cool down before working on the system.

Intended Use:

The module is intended for controlling or switching one or more electrical systems or subsystems in vehicles and machinery. It must only be used for this purpose and operated in industrial environments. It is not suitable for use in safety-critical systems for personal protection or in potentially explosive atmospheres.

System Manufacturer Obligations:

• System development, installation, and commissioning must be performed by trained and experienced personnel.
• Only functional modules should be used. Faulty or malfunctioning modules must be replaced immediately.
• Ensure that the wiring and programming of the module do not lead to safety-critical malfunctions of the overall system in case of failure or error.
• The system manufacturer is responsible for the correct connection of all peripherals (e.g., cable cross-sections, connectors, crimps, correct selection/connection of sensors/actuators).
• The module must not be opened. No modifications or repairs may be carried out on the module.

Mounting:

• Choose a mounting location that exposes the module to minimal mechanical and thermal stress. The module must not be exposed to chemical stress.
• If the module has been dropped, it must not be used and must be returned to MRS for inspection.
• Mount the module with connectors facing downwards to allow condensation to drain. Ensure that no water can enter the module by individually sealing the cables/wires.

Commissioning:

• Commissioning must only be performed by qualified personnel.
• Commissioning is only permitted when the state of the overall system complies with applicable guidelines and regulations.

Troubleshooting and Maintenance:

• NOTE: The module is maintenance-free and must not be opened!
• If the module shows damage to the housing, retaining clips, seals, or connectors, it must be taken out of service.
• Troubleshooting and cleaning must be performed with the power off. Remove the module for troubleshooting and cleaning. Refer to other technical documentation for instructions.
• Check the module's integrity and all connectors, connections, and pins for mechanical damage, overheating, insulation damage, and corrosion. In case of incorrect connections, check the software, wiring, and parameterization.
• Do not clean the module with high-pressure cleaners or steam jets. Do not use aggressive cleaning or scouring agents.
