IFE HAZARD
!
When testing 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. In view
of this, additional safety precautions are
required when performing any testing
operations.
1. Earth the cable via the integrated earthing of the load-
break switch or circuit-breaker (see chapter 4.3.1).
Disconnect any cable side voltage transformer and
overvoltage deflectors (if present) (see chapter 4.2.9).
2. Open the relevant protection cover by turning the key a
quarter turn counterclockwise and remove the panel.
3. Move the shutter of the cable entry port up.
4. Insert the pins in the cable entry port and connect the
metering or voltage testing equipment (figure 1).

5. Turn the load-break switch or circuit-breaker off (see
chapter 4.2.2 / 4.2.3).

Metering or voltage testing can now be carried out.
6. Immediately after metering or voltage testing, turn the
load-break switch or circuit-breaker on (see
chapter 4.2.2/4.2.3).
7. Remove the pins.
8. Move the shutter of the cable entry port down.
9. Close the protection cover and lock it by turning the key
a quarter turn clockwise.
