1. Safety precautions
Read the operational manual carefully before switching on the
regulator. Do not repair or maintain the regulator yourself.
1.1. Electric safety
Electric safety:
• operate the device with damaged wiring insulation;
• operate the device without protective grounding;
• touch bare cables and electrical connections by your hands;
• operate the regulator in direct contact with liquid (rain, snow
etc.), as well as under the conditions of increased humidity;
• use a one-phase network to connect voltage regulators with-
out a earthing.
The one-phase Quant voltage regulator goes on sale in a state
that complies with safety regulations.
Do not disassemble the regulator. Do not remove the protective
elements of the housing.
1.2. Fire safety
Do not operate the regulator near flammable materials.
Do not block the ventilation openings, do not operate the regula-
tor in a confined space (box, cabinet), i.e. in conditions of insuffi-
cient ventilation.
Do not operate the regulator in direct sunlight or in atmospheric
precipitation.
1.3. General safety precautions
• keep children away from the regulator, even is it’s off;
• do not cover the regulator with foreign items during operation
(an emergency or ignition of foreign items may occure);
• do not allow foreign items to get inside the regulator;
• it is forbidden to connect a constant load that exceeds the
maximum load of the voltage regulator;
• if the regulators have been stored or transported at a tem-
perature lower than 0°c, they must be left in a room at room
temperature for at least 5 hours before installation;
• if the input wire is constantly heated due to high current, tight-
en the stabilizer input terminal screw. if the input wire contin-
ues to heat up, make sure that it has sufficient cross-section
for the regulator power according to the wiring material spec-
ification;
• install/remove regultaros only when the input circuit breaker
is switched off.
