SAFETY PRECAUTIONS
• Check if the supply voltage is correct before connecting the instrument.
• Do not expose the back of the instrument to water or moisture: use the controller only within the operating limits
avoiding sudden temperature changes with high atmospheric humidity to prevent the formation of condensation.
• Warning: disconnect all electrical connections before performing any maintenance operation.
• Fit the probe where it is not damaged by the end-user. The instrument must not be opened.
• In case of failure or faulty operation send the instrument back to the distributor (see address) with a detailed
description of the fault.
• Consider the maximum current that can be applied to each relay (see Technical Data).
• Ensure that the wires for probes, loads and the power supply are separated and far enough from each other, without
crossing or intertwining.
