1) To install the instrument on a DIN rail, raise the clamp at the
back of the instrument and place it on the rail. Now release
the clamp, so the instrument fits on the DIN rail.
2) Ensure proper fitting of the instrument by pulling it outwards.
3) To remove the instrument raise the clamp to release it from
the DIN rail.
4) The equipment in its installed state must not come in close
proximity to any heating source, caustic vapors, oil steam, or
other unwanted process byproducts.
5) Do not connect anything to unused terminals.
Read complete instructions prior to installation
and operation of the unit.
WARNING :
Risk of electric shock.
SAFETY PRECAUTION
!
All safety related codifications, symbols and instructions
that appear in this operating manual or on the equipment
must be strictly followed to ensure the safety of the operating
personnel as well as the instrument.
If all the equipment is not handled in a manner specified
by the manufacturer, it might impair the protection provided
by the equipment.
WARNING GUIDELINES
WARNING : Risk of electric shock.
1) To prevent the risk of electric shock, power supply to the
equipment must be kept OFF while doing the wiring
arrangement. Do not touch the terminals while power is
being supplied.
2) To reduce electro magnetic interference, use wire with
adequate rating and twists of the same of equal size shall
be made with shortest connection.
3. Cable used for connection to power source, must have a
cross section of 1mm or greater. These wires should have
insulations capacity made of at least 1.5kV.
4) A better anti-noise effect can be expected by using
standard power supply cable for the instrument.
1) 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.
2) Circuit breaker or mains switch must be installed
between power source and supply terminal to facilitate
power ‘ON’ or ‘OFF’ function. However this mains switch
or circuit breaker must be installed at convenient place
normally accessible to the operator.
INSTALLATION GUIDELINES
3) Use and store the instrument within the specified ambient
temperature and humidity ranges as mentioned in this
manual.
1) The equipment should be cleaned regularly to avoid blockage
of ventilating parts.
2) Clean the equipment with a clean soft cloth. Do not use
isopropyl alcohol or any other cleaning agent.
MAINTENANCE
3) Fusible resistor must not be replaced by operator.
