Hints On Correct Use
Tools and Fasteners Kindly use star – type screw driver for tightening the screws.
NOTE: Installation should include a disconnecting device, like switch or circuit breaker, with clear ON/OFF markings, to turn-off the auxiliary
supply(control power).The disconnecting device should be within the reach of the equipment and the operator.
Caution

NEVER work alone.
Turn OFF all power supplying the energy meter and the equipment in which it is installed before working on it.
The successful operation of this equipment depends upon proper handling, installation and operation. Neglecting fundamental installation
requirements may lead to personal injury as well as damage to electrical equipment or other property
NEVER bypass external fusing.
NEVER short the secondary of PT
NEVER open circuit a CT; use the shorting block to short circuit the leads of CT before removing the connection from energy meter.
Before performing Dielectric or Megger testing on any equipment in which the energy meter is installed, disconnect all the input and output
wires to the energy meter. High voltage testing may damage electronic components contained in the energy meter.
The energy meter should be installed in a suitable electrical enclosure
EAPL is not responsible for any consequential damages arising out of use of our products, though the technology is cautiously chosen and
implemented like any other well designed good electric meter.
