When earthing the cable via the 17.5 kV cable
terminal block in combination with a direct
busbar connection, the shutter is secured in
front of the cable entry ports. The contacts
behind this shutter are directly connected to the
main busbar system of the installation. This
requires extra safety measures.
1. Earth the cable via the integrated earthing of the load-
break switch or circuit-breaker (see chapter 4.3.1).
2. Open the relevant protection cover by turning the key a
quarter turn counterclockwise and remove the panel
(figure 1).

The shutter can only be opened if the
disconnector is in the earthing position and the
circuit-breaker or load-break switch is closed.
3. Connect the earthing cable to the earth plate using the
ball-head bolt connection (figure 2).
4. Fit the 3 earthing pins to the connection points on the
earthing cables (figure 3). Proceed as follows:

Move the shutter of the cable entry port up and
insert the pins in the cable entry port using the
mounting rod.
