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 0.5mm
2
to 2.5mm
2
. 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.
4. 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.
5. The equipment shall not be installed in environmental
conditions other than those mentioned in the manual.
6. The equipment does not have a built-in-type fuse.
Installation of external fuse of rating 275Vac / 0.5Amp for
electrical circuitry / battery is highly recommended.
