the wiring arrangement. Do not touch the
terminals while power is being supplied.
2. To eliminate electromagnetic interference use

2 have across section of 1mm or greater. These
wires shall have insulation capacity made of at
least 1.5kV.

becomes a part of main control panel and in such
case the terminals do not remain accessible to the
end user after installation and internal wiring.
2. Do not allow pieces of metal, wire clippings, or
fine metallic fillings from installation to enter the
product or else it may lead to a safety hazard that
may in turn endanger life or cause electrical shock
to the operator.

installed between power source and supply
terminals to facilitate power 'ON' or ‘OFF’
function. However this switch or breaker must be
installed in a convenient position normally
accessible to the operator.
