Din sized enclosure with Auto / manual Switch
LED indication for relay status
CT primary can be programmed up to 2500 in steps of 5. CT secondary will be factory set for 5.
User can set the in-rush time delay.
PVMD, PVMD-G :Monitors and trips the circuit after the set trip delay time when ever power
unhealthiness (phase failure, phase sequence, phase unbalance under voltage or over voltage)
occurs.
Displays all the 3 phase voltages in a scrolling fashion during healthy condition.
PVMD – Panel / Flush mounting, PVMD-G Din rail mounting.
PVIMD, PVIMD-G: Monitors and trips the circuit after the set trip delay time when ever power
unhealthiness (phase failure, phase sequence, phase unbalance under voltage, over voltage, under
current or over current)
Displays all the 3 phase voltages and 3 phase currents in a scrolling fashion during healthy condition.
User can program nominal current. Under current and over current limits can be set in percentage
with reference to nominal current .

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.

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.
