Safety
- WARNING! Danger as a result of a malfunction of the entire system. Unforeseen reactions or malfunctions of the entire system may jeopardize the safety of people or the machine. Ensure correct software, wiring, and hardware settings.
- WARNING! Danger as a result of unprotected moving components. Switch off the entire system before any work and prevent unintentional switching back on. Ensure the entire system and its parts are safe before operation. Never connect or separate the device under load or voltage.
- CAUTION! Risk of burns from the housing. The device housing temperature may be elevated. Do not touch the housing and allow all system components to cool before working on the system.
Proper Use
The device is used to control or switch electrical systems or sub-systems in motor vehicles and machines. It may only be used in an industrial setting.
- WARNING! Danger caused by incorrect use. The device is only intended for use in motor vehicles and machines. Use in safety-related system parts for personal protection is not permitted. Do not use in areas with a risk of explosion.
- Operate the device within specified operating areas. Strict compliance with instructions is required.
Obligations of the manufacturer of entire systems
Ensure only functional devices are used. If devices fail or malfunction, they must be replaced immediately. System developments, installation, and commissioning of electrical systems must be carried out by trained and experienced staff. Ensure wiring and programming do not lead to safety-related malfunctions. The manufacturer of the entire system is responsible for correct connection of the periphery (e.g., cable cross sections, sensor/actuator selection/connection).
Opening the device, making changes, or carrying out repairs is prohibited. Repairs may only be carried out by MRS.
Installation
Select an installation location with minimal mechanical and thermal load. The device must not be exposed to chemical loads. Install the device with plugs pointing downwards so condensation can flow off. Use single seals on cables/leads to prevent water ingress.
Putting into operation
The device may only be put into operation by qualified staff, ensuring the entire system status corresponds to applicable guidelines and regulations.
Fault Correction and Maintenance
NOTE: The device is maintenance-free and may not be opened. If the device has damage to the housing, seals, or plugs, it must be taken out of operation. Fault correction and cleaning must be carried out with the power turned off. Remove the device to correct faults and clean it. Check housing, plugs, connections, and pins for mechanical damage, overheating, insulation damage, and corrosion. For faulty switching, check software, switches, and settings. Do not clean with high-pressure cleaners or steam jets. Do not use aggressive solvents or abrasive substances.
