1P2W Mode Installation
For Installation and Commissioning, proceed the following instructions.
1. Push the unit into the panel and mount using the clamps provided. Connect
the auxiliary supply (80 VAC to 270 VAC) to the terminal marked P and N.
2. Connect the R-Phase (Single phase) to the terminals marked U1. Make sure
that the phase coming to the unit comes 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.
5. Switch on the single 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 page.
6. The unit should be programmed for all the required parameters which are field
programmable and therefore, for selecting the various options supported,
refer Operational Details in next section.
7. Now, the unit is ready for operation.
