Important notes
Warning
In order to ensure the reliable performance of
the equipment and the safety of the user,
please observe the following matters during
the process of installation, use and
maintenance:
The matters needing attention of
installation
◆Please do not use this product in the
following places: the place of dust, soot and
electric conductivity dust, corrosive gas,
combustible gas; the place exposed to high
temperature, condensation, wind and rain; the
occasion of vibration and impact . Electric
shock, fire, wrong operation can lead to
damage and deterioration to the product,
either;
◆In processing the screw holes and wiring,
make sure that metal scraps and wire head will
not fall into the shaft of controller, as it could
cause a fire, fault, or incorrect operation;
◆When the installation work is over, it should
be assured there is nothing on the ventilated
face, including packaging items like dust
paper. Otherwise this may cause a fire, fault,
incorrect operation for the cooling is not free;
◆Should avoid wiring and inserting cable
plug in charged state, otherwise it is easy to
cause the shock, or electrical damage;
◆The installation and wiring should be strong
and reliable, contact undesirable may lead to
false action;
◆For a serious interference in applications,
should choose shield cable as the high
frequency signal input or output cable, so as to
improve the anti-jamming ability of the
system.
Attention in the wiring
◆Only after cutting down all external power
source, can install, wiring operation begin, or
it may cause electric shock or equipment
damage;
◆This product grounds by the grounding
wires .To avoid electric shocks, grounding
wires and the earth must be linked together.
