Installing and working with the equipment.
240V AC/DC,-20 to +10%
50 / 60Hz ± 5% for AC only
AC Approx. 6 VA
HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH
DC Approx. 4W
 Apply appropriate personal protective equipment(PPE) and follow safety work
3 Phase 4 wire (R,Y,B,N)
practices
415 VAC (-40% to +20%)
 Only qualified electrical workers should install this equipment. Such work should
110 VAC (-40% to +20%)
be performed only after reading this entire set of instructions.
Current inputs (AR, AY, AB)
 If the equipment is not used in the manner specified by the manufacturer, the
1A to 5A (to 200%)
protection provided by the equipment may be impaired.
50 Hz,  2%
 NEVER work alone.
 Turn OFF all power supplying the energy meter and the equipment in which it is
< 0.2 VA per Volts/Amps input
installed before working on it.
Class 1.0 For Active Energy
 The successful operation of this equipment depends upon proper handling,
Class 2.0 For Reactive Energy
installation and operation. Neglecting fundamental installation requirements
Up to 20Sec per month
may lead to personal injury as well as damage to electrical equipment or
other property.
2 sec minimum
 NEVER bypass external fusing.
RS-485 MODBUS RTU Protocol
 NEVER short the secondary of PT
3200 Pulses/KWh
 NEVER open circuit a CT; use the shorting block to short circuit the leads of CT
3200 Pulses/KVArh
before removing the connection from energy meter.
Approx 2yrs
 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
Primary 1 to 5KA max
contained in the energy meter.
Secondary 1 to 5A
 Ensure neutral wire is intact
Primary 110 to 11KV
 The energy meter should be installed in a suitable electrical enclosure.
Secondary 110 to 500V
 If unit switches off due to over voltage. Switch off the unit for 1 minute to reset
