InstallationCategory III
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.
4.
5. The equipment shall not be installed in environmental
conditions other than those mentioned in this manual.
. The equipment does not have a built-in-type fuse.
Installation of external fuse of rating 275V AC / Amp for
electrical circuitry is highly recommended.
Before disconnecting the secondary of the external
current transformer from the equipment, make sure that
the current transformer is short circuited to avoid risk of
electrical shock and injury.

INSTALLATIONGUIDELINES
CAUTION:
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 used in a manner specified by
the manufacturer it might impair the protection provided
by the equipment.
Do not use the equipment if there is any mechanical
damage.
Ensure that the equipment is supplied with correct
voltage.
1. Read complete instructions prior to installation and
operation of the unit.
2. Riskofelectricshock.
3. The equipment in its installed state must not come in
close proximity to any heating sources, oils, steam, caustic
vapors or other unwanted process by products.
CAUTION:
WIRINGGUIDELINES
WARNING :
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. 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

PROCESSINTEGRATION
Pulse output from meter can be used as alarm generator
or total energy controller by interfacing it with Pre
settable counter and control circuits (Contactors, Relay,
Trip Circuit).
The counter is loaded with the maximum energy
consumption. When count reaches setpoint it provides
output to control circuit to take appropriate action.
