3.3.2 REAR DESCRIPTION
The relay is wired through the terminal blocks located at the rear of the unit.
The magnetic module, which receives the CT secondary currents and the metering voltages, incorporates a very robust
terminal board (columns A and B). Current inputs provide automatic shorting of external CT circuits. 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, F and G for I/O and H for power supply, 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.

WARNING
Module withdrawal and insertion may only be performed when control power has been removed from the unit.
Proper electrostatic discharge protection (i.e. a static wrap) must be used when coming in contact with
products while the relay is energized.
