3.2.2 REAR DESCRIPTION
The relay is wired through the terminal blocks located at the rear of the unit. Terminal blocks vary depending
on their functionality. The magnetic module, which receives the CT secondary currents and the metering
voltages, incorporates a very robust terminal board (columns A and B). In this terminal board, current terminals
are shorted two-by-two when the transformer module is extracted, so that the CT secondary never remains
open. For safety reasons it is not allowed to change or swift the magnetic module terminals. The
maximum recommended cable section for this terminal board, with the appropriate terminal, is 6 mm
2
(AWG
10).
The rest of the terminal blocks (columns F, G, and H), for power supply, inputs/outputs and IRIG-B, incorporate
high quality connectors with the capacity to withstand a rated current of 15 A at 300 V. These terminal blocks
admit a cable section of up to 2.54 mm
2
(AWG 12).
The communication boards have a different type of connector depending on the selected media: RS485, glass
or plastic fiber optic.
