3.1.3 REAR DESCRIPTION
The relay is wired through the terminal blocks located at the rear of the unit. 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.
Figure 3–3: REAR VIEW
The magnetic module with the CTs is already connected to a female connector screwed to the case that incorporates
shorting bars in the current inputs, so that it can be extracted without the need to short-circuit the current externally.
A grounded antistatic wristband must be used when manipulating the module in order to avoid electrostatic discharges
that may cause damage to the electronic components.
In a similar way, when mounting and dismounting the front of the unit, be sure to correctly align the DIN connector of the
rear bus with the DIN connectors of the module. A slow and careful insertion must be made until the module is correctly
aligned, and then a more firm insertion can be applied, never forcing the module.
