Ensure the input voltage matches the rated voltage of ZMI 4104 (check the product nameplate for specific values) before connecting the power supply. Using an incorrect voltage may cause equipment damage or fire hazards.
Always turn off the main power switch before plugging in or unplugging the power cord to avoid electric shock.
Environmental Requirements
Install ZMI 4104 in a well-ventilated area. Avoid placing it in enclosed spaces, near heat sources (such as radiators, stoves, or high-power electronic devices), or in humid/dusty environments. Poor ventilation can lead to overheating and shorten the product lifespan.
Ensure the installation surface is flat, stable, and can bear the weight of the device. Do not install it on unstable platforms (like wobbly shelves) to prevent the device from falling and being damaged.
Wiring Operations
Use wires that meet the current-carrying capacity requirements of ZMI 4104 (refer to the user manual for wire gauge specifications). Using undersized wires may cause overheating and wire insulation damage.
When connecting wires to terminals, ensure the connections are tight and secure. Loose connections can result in poor contact, sparking, or even equipment failure. Do not leave exposed wire strands outside the terminals to avoid short circuits.
Confirm the correct wiring sequence (e.g., positive/negative poles, signal lines) according to the user manual. Wrong wiring may damage internal components of the device.
Post-Installation Inspection
After installation, visually inspect all connections to ensure no wires are misconnected, pinched, or damaged. Check if the device is properly fixed and there is no looseness.
Turn on the power supply and conduct a functional test (e.g., check if indicator lights work normally, test basic functions as per the manual) to confirm that ZMI 4104 operates correctly. If any abnormal phenomena (such as strange noises, smoke, or error indicators) occur, immediately turn off the power and troubleshoot.
Maintenance and Prohibition
Do not disassemble, modify, or repair ZMI 4104 by yourself unless you are a professional technician authorized by the manufacturer. Unauthorized operations may void the warranty and cause safety risks.
Regularly clean the surface of the device with a dry, soft cloth to remove dust. Do not use water, alcohol, or corrosive cleaning agents to wipe the device, as this may damage the casing or internal circuits.
