Safety
This transducer must used electric/electronic equipment with respect applicable standards safety requirements accordance with manufacturer's operating instructions. Installation maintenance should done with main power supply disconnected. operator must have accreditation install this material.
Caution! Risk electrical shock When operating transducer, certain parts module carry hazardous voltage (e.g. primary conductor, power supply). Ignoring this warning lead injury and/or cause serious damage. user must take care protection guarantee against electrical shock. This transducer built-in device, whose conducting parts must inaccessible after installation. protective housing additional shield could used.
