Introduction
E3-DMM-5T-2 is a multifunction, universal metering device used for overall monitoring of one- or three-phase power
supply line parameters. The analyzer enables the user to make high-precision measurements of all crucial network
parameters, such as: voltage and phase currents, phase-to-phase voltage, active power, reactive power, apparent po-
wer, power factor. In addition, the analyzer ensures full, four-quadrant metering (both imported and exported to the
network) and analyzes the distribution of harmonics of voltage and current up to 63rd harmonic inclusive.

Assembly
Safety precautions
The analyzer must be installed and connected by qualified
personnel. All available safety requirements must be taken
into consideration.
Supply voltage
E3-DMM-5T-2 multifunction meter is powered through potential terminals V1,
V2, V3, N and doesn’t require auxiliary power supply.
It is recommended to protect power supply and voltage circuits of the
meter using 1A fuse link.
Measurement voltage
Maximum value of measurement voltage cannot exceed 280 V AC (phase
voltage between terminals L-N) or 500 V AC (phase-to-phase voltage between
terminals L-L). When maximum value of measurement voltage is exceeded, it
may lead to damage to the device.
Measurement current
The multifunction meter can be applied for direct measurements of current
with application of current transformers with the secondary current of 5 A.
If measurement current exceeds 6 A, it may lead to damage to the device.
Environmental conditions
The device can be operated at the temperature from -25°C to +55°C and air
humidity lower than 90%. Exceeding those limiting parameters may lead to
improper operation and damage to multifunction meter.

You must make a hole 92x92mm in the panel, thickness of the material the panel was made of cannot exceed 5 mm.
Multifunction meter is adapted for mounting in E3 system frames, e.g. 36422-0010.
Multifunction meter must be inserted from the front of the panel, when all wires are disconnected, and must be
pressed to the surface of the panel. Having assembled the multifunction meter on the panel, you can proceed to
connecting the wires. Distribution of terminals scheme is presented in Fig. 2.
