SAFETY PRECAUTIONS
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 the equipment is not handled in a manner specified
by the manufacturer it might impair the protection provided
by the equipment.
CAUTION : Read complete instructions prior to
installation and operation of the unit.
CAUTION : Risk of electric shock.
WIRING GUIDELINES
CAUTION :
1. To prevent the risk of electric shock power supply to
the equipment must be kept OFF while doing the wiring
arrangement.
2. Wiring shall be done strictly according to the terminal
layout with shortest connections. Confirm that all
connections are correct.
3. Use lugged terminals to meet M3 screws.
4. To eliminate electromagnetic interference use of short
wire with adequate ratings and twists of the same in
equal size shall be made.
5. Cable used for connection to power source, must have
2
a cross section of 1mm or greater. These wires shall
have insulation capacity made of at least 1.5KV.
MAINTENANCE
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.
INSTALLATION GUIDELINES
CAUTION :
1. This equipment, being built-in-type, normally 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. Conductors must not come in contact with the internal
circuitry of the equipment or else it may lead to a
safety hazard that may in turn endanger life or cause
electrical shock to the operator.
3. Circuit breaker or mains switch must be 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.
CAUTION :
1. The equipment shall not be installed in environmental
conditions other than those mentioned in this manual.
2. Fuse Protection : The equipment does not have a built
in-type fuse. Installation of external fuse of rating 275V
AC/1Amp for electrical circuitry is highly recommended.
3. Thermal dissipation of equipment is met through
ventilation holes provided on chassis of equipment.
Such ventilation holes shall not be obstructed else it
can lead to a safety hazard.
4. The output terminals shall be strictly loaded to the
manufacturer specified values/range.
MECHANICAL INSTALLATION
For installing the controller
1. Prepare the panel cutout with proper dimensions as
shown
OUTLINE PANEL CUTOUT
Dimensions (in mm) Dimensions

10
2. Remove clamp from the controller and push the
controller into the panel cutout. Secure the controller in
its place by pushing the clamp on rear side.
3. For proper sealing, tighten the screws evenly with
required torque.
CAUTION:
The equipment in its installed state must not come in
close proximity to any heating sources, caustic vapors,
oils, steam, or other unwanted process by-products.
EMC Guidelines:
1. Use proper input power cables with shortest connections
and twisted type.
2. Layout of connecting cables shall be away from any
Internal EMI source.
