3 Normal use, installation and transport conditions
3.1 Normal use and installation conditions
a) The upper limit of ambient air temperature does not exceed +70℃, the lower limit does not exceed -35℃,
and the average temperature within 24 hours does not exceed +35℃;
b) The altitude of the installation site does not exceed 2000m;
c) When the temperature is +40°C, the relative humidity of the air does not exceed 50%; at a lower
temperature, a greater relative humidity is allowed. For example, at +20°C, the relative humidity does not
exceed 90%. Special protective measures shall be taken for the condensation produced occasionally due to
temperature changes;
d) The external magnetic field near the circuit breaker installation site should not exceed 5 times the
geomagnetic field in any direction;
e) Installed in a medium without explosion hazard, and there is no enough gas and dust that cause corrosion
to metals and destroy to insulation in the medium;
f) Installed in the place without significant impact vibration and rain and snow invasion;
g) Pollution level: Level 2;
h) Installation category: CategoryⅡ , Category Ⅲ ;
i) Installed in the power distribution box, electric distribution cabinet or box;
j) Reverse wiring is allowed for product;
k) When wiring products with N pole, connect the neutral wire (zero line) to the pole marked with N.
3.2 Normal storage and transport conditions
a) The lower temperature limit is not less than -40℃, and the upper limit is not more than +85℃;
b) Relative humidity (at 25℃ ) does not exceed 95%;
c) Handle the product gently during transport, do not upside it down and try to avoid violet collisions.
