Apply appropriate personal protective equipment(PPE) and follow safety work practices
Only qualified electrical workers should install this equipment. Such work should be performed only after reading this entire set of instructions.
If the equipment is not used in the manner specified by the manufacturer, the protection provided by the equipment may be impaired.
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 apply the voltages at Program Lock and Auto Reset terminals.
Before performing Dielectric or Megger testing on any equipment in which the monitoring device is installed, disconnect all the input and
output wires to the monitoring device. High voltage testing may damage electronic components contained in the monitor
The monitoring device 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 device.
