Safety
Vaisala Moisture, Hydrogen and Temperature Transmitter MHT410 for
Transformer Oil delivered to you has been tested for safety and approved as
shipped from the factory. Note the following precautions:
Read this whole guide carefully before installing the product.
Ground the product and verify outdoor installation grounding
periodically to minimize shock hazard.
Severe risk of death and of damage to transformer:
Pay attention to transmitter installation depth and possible
energized parts inside the power transformer to minimize electric
shock hazard and equipment damage.
Do not modify the unit. Improper modification can damage the
product or lead to malfunction.
Do not try to close the ball valve when the transmitter is fully
installed. The probe body goes through the valve into the oil flow,
and trying to close the valve will damage the probe body.
If you must close the ball valve while the transmitter is on the
valve, first open the small tightening nut and pull the probe body
out as far as possible. Then close the valve.
