TINYPRO6 – Operational Manual
TRINITY
[8]
To install and commission for 3P3W, proceed the following instructions:
1. Push the unit into the panel and mount using the claim provided on it.
2. Connect the auxiliary supply (80V AC to 270V AC) to the terminals marked P
and N.
3. Connect the three phases with the phase sequence being R-Y-B to the
terminals marked U1, U4 and U3 respectively. Make sure that the phases
coming to the unit come through control fuses of 1.0A rating. This will protect
the electronic inside from damage due to severe over voltage or phase faults
in the system.
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.
5. Connect the two wires from the B-phase CT to the terminals marked M3 and
L3 such that S1 from the CT goes to the terminal marked M3.
6. Switch on the auxiliary supply as well as three phases supply and then, the
unit will come alive in order to display such as TRINITY ESPL, CT ratio, unit
Address and Run Mode respectively.
7. Firstly, user should program the settable parameters, CT-primary and unit
address for RS485 communication port as required. (Refer Operational
Details in the next section).
8. Now, the unit is ready for operation.
