Installation (Continued)
1. Insert unit into the panel 2. Position the clamps (as shown in the
gure) and push the same into the slots in
their respective locations.
3. Push/Slide all 4 clamps towards the panel
evenly till the lowest possible tooth of the
clamp is engaged. Ensure the meter is
properly tightened and it does not move.
Note: Terminal screw tightening torque: 0.7 N-m to 0.8 N-m (6 In-Lb to 7 In-Lb)
Mounting distance
The distance to be maintained between two meters while
mounting on a panel door should be at least 100 mm.
Installation Guidelines
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. 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 this manual.
6. The equipment does not have a built-in-type fuse.
Installation of external fuse of rating 275V AC / 0.5Amp for
electrical circuitry is highly recommended.
7. Remove the scratch-guard from the meter display during
commissioning of the panel.
