Isolating and earthing the voltage transformers
or voltage sensors
To isolate and earth the voltage transformers or
voltage sensors, slide the locking plate (1) upwards
and pull the actuating plate (2) to the front until the
stop is reached. Allow the locking plate to slide into

When the locking plate engages in the
latching slot of the actuating plate, the
dielectric strength of the isolating device
is ensured.
Connecting the voltage transformers or voltage
sensors
To connect the voltage transformers or voltage
sensors, slide the locking plate (1) upwards and
pull the actuating plate (2) to the rear until the
stop is reached. Allow the locking plate to slide
into the appropriate latching slot (4) in the
actuating plate (Fig.4.4.3).

When the locking plate engages in the
latching slot of the actuating plate, the
current carrying capacity of the isolating
device is ensured.
Secure the isolating device with a padlock.
