Installation and Commissioning
The unit supports three types of electrical installation such as 3P4W/3P3W/1P2W.
According to user’s requirement, the three electrical installation types can be
selected either.
3P4W Mode Installation
For Installation and Commissioning, proceed the following instructions.
1. Push the unit into the panel and mount it by using the clamps provided.
Connect the Auxiliary supply (80 VAC to 270 VAC) to the terminals marked P
and N.
2. Connect the three phases with the phase sequence being R-Y-B to the
terminals marked U1, U2 and U3 respectively. Make sure that the three
phases coming to the unit come through control fuses of 1.0 Amp rating. This
will protect the electronic inside from damage due to severe over voltages or
phase faults in the system.
3. Connect the neutral wire to the terminal marked U4.
4. Connect the two wires from the R-Phase CT to the terminals marked M1 and
L1 such that S1 from CT goes to M1 on the unit. Connect the two wires from
the Y-phase CT to the terminals marked M2 & L2 such that S1 from the Y-
phase CT goes to M2 on the unit. Connect the two wires from the B-phase CT
to the terminals marked M3 & L3 such that S1 from CT goes to M3 on the
unit.
5. Switch on the three phases supply as well as the auxiliary supply. The unit will
come alive and display such as Firmware Version, CT Ratio, Device ID and
Installation type and then, the unit enters into Run Mode displaying the first
