Precautions
■Rated input voltage and range
?? This instrument (isolator) is powered by 24VDC power supply. It is strictly forbidden to use 220V AC power.
?? The power supply voltage range is 20~30VDC.
■Working environment
?? Install this meter (isolator) in a safe place.
?? The instrument is protected to IP20 (IEC 60529 / EN 60529) and is suitable for use in a clean, dry environment.
?? Ambient temperature is -20 ~ 60 ° C (continuous operation), relative humidity is 5 ~ 95% RH (no condensation) to ensure that the instrument has a sufficient service life.
■Safety measures
? When you install or remove the meter, turn off the power and disconnect the signal input to ensure safety.
? Do not apply a load to the meter that exceeds its design capabilities.
?? It is strictly forbidden to disassemble the instrument or change the circuit device to prevent the instrument from failing or malfunctioning.
?? In the event of instrument damage, improper load or malfunction, stop the instrument and immediately withdraw it.
■ Wiring
? The wiring cable of the instrument should be away from sources of electromagnetic interference (eg relay drive cable, high frequency line, etc.). It is not possible to install the wiring cable in the same conduit as the electromagnetic interference source.
?? The wiring cable is a single-core or multi-core cable with a section of 0.5~2.5mm2. The insulation strength of the wiring cable should be greater than 500V.
