Do not install in humid, condensed water, dusty and corrosive gas environments.
Keep away from high-power cables and frequency converters to avoid analog signal induction interference.
Cut off all power supply before wiring, disassembly and module replacement operations.
Prohibit over-range voltage and current input to prevent internal operational amplifier and sampling chip damage.
Avoid severe vibration and mechanical impact during transportation and installation.
Ensure cabinet ventilation and heat dissipation to prevent signal drift caused by high temperature.
Unauthorized disassembly and modification of internal components is strictly prohibited.
