Selec MV Series User manual

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.

For installing the meter
1. Prepare the panel cutout with proper dimensions as shown
below.
2. Push the meter into the panel cutout. Secure the meter in its
place by pushing the clamp on the rear side. The clamps
must be secured in diagonally opposite slots.
3. For proper sealing, tighten the screws evenly with required
torque.
Terminal screw tightening torque :
0.68 N-m to 0.79 N-m (6.018 In-Lb to 6.992 In-Lb)
Screw clamp tightening torque : 0.1N-m (0.885 Lb-inch)
MECHANICAL INSTALLATION
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, caustic vapors, oils, steam,
or other unwanted process by products.
WIRING GUIDELINES
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
2 2 0
crosssectionof 0.5mm to 2.5mm (20 to 14AWG; 75 C(min)).
Thesewires shall have current carryingcapacityof 6A.
7. Copper cable should be used (Stranded or Single core cable)
8. Before attempting work on device, ensure absence of
voltages using appropriate voltage detection device.
