SAFETY PRECAUTIONS
All safety related codifications, symbols and instructions that
appear in this operation 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 used in the manner specified by the
manufacturer it might impair the protection provided by the
equipment.
CAUTION
Read the instructions prior to installation
and operation of the unit .
CAUTION
Risk of electrical shock
WIRING GUIDELINES
WARNING
1. To prevent the risk of electric shock, power supply to the
equipment must be kept OFF while installing the wiring.
2. Wiring shall be done strictly according to the terminal
layout. Confirm that all connections are correct.
3. Use lugged terminals.
4. To reduce electromagnetic interference use of wires with
adequate ratings and twists of the same in equal size shall
be made with shortest connections.
5. Layout of connecting cables shall be away from any
internal EMI source.
6. Cable used for connection to power source, must have a
cross section of 0.5mm2 to 2.5mm2. These wires shall
have current capacity of 6A.
7. Copper cable should be used (Stranded or single core
cable).
8. Before attempting work on the device ensure absence of
voltages using appropriate voltage detection device.
INSTALLATION GUIDELINES
CAUTION
1. This equipment, being of a built-in-type, normally becomes
a part of a main control panel and in case the terminals do
not remain accessible to the end user after installation and
internal wire.
2. Conductors must not come into contact with the internal
circuitry of the equipment or it may lead to a safety hazard
that may in turn endanger life or cause electrical shock to
the operator.
3. Protection & disconnection means must be installed
between power source and supply terminals to facilitate
power 'ON' or 'OFF' function & must be installed in a
convenient position normally accessible to the operator.
SERIAL NUMBER DESCRIPTION
Press PF key for 10 seconds to 8 digit serial number only for
10 seconds on the fifth line of the display
MECHANICAL INSTALLATION
For installing the meter
1. Prepare the panel cut out with the dimensions as shown below.
Meter Outline Panel Cut-out
Dimensions (In mm) Dimensions (In mm)
2. Push the meter into the panel cut-out. Secure the meter in its place by
fitting the clamp from the rear side. Fit clamps on both sides in
diagonally opposite location for optimum fitting.
3. For proper sealing, tighten the screws evenly with required torque.
2
4. Recommended conductor cross section = 1.5mm .
Screw clamps tightening torque = 0.1N-m
CAUTION
The equipment in its installed state must not co in close proximity to any
heating sources, caustic vapour, oil, steam or other unwanted process
by-products.
EMC Guidelines
1. Use input power cable with shortest connections.
2. Layout of connecting cables shall be away from any internal EMI
source.
TERMINAL CONNECTIONS
LEFT HAND CT MOUNTING PHASE CORRECTION
The meter phases L1, L2 & L3 are setup as default for the CT to be
mounted as an incomer on the RH (Right Hand) side of the board.
Meter display shows rH when "I" is pressed for 3 seconds.
When the CT is mounted on the LH (Left Hand) side of the board the
phase sequence needs to be reversed.
1. Press "I" for 3 seconds, then release and then press again for
3 seconds. Phase will be reversed and the display will show
LH.
2. Wait 5 seconds for the meter to resume online reading. Meter
display shows LH when "I" is pressed for 3 seconds.
