can be secured with a padlock (3). Remove the padlock prior to
operation.
Isolating the voltage transformers
To isolate the voltage transformers, pull out the lock knob (2) and
turn the operating lever (1) counter-clockwise as shown on the
direction of rotation indicator (4). Release the lock knob. Turn the
operating lever counter-clockwise until the lock knob engages in
the limit position of the isolating device.
?
When the lock knob engages in the limit position,
the dielectric strength of the isolating device
is ensured.
Secure the isolating device with a padlock in the “OFF” position
(8).
Connecting the voltage transformers
To connect the voltage transformers, pull out the lock knob (2) and
turn the operating lever (1) clockwise as shown on the direction of
rotation indicator (4). Release the lock knob. Turn the operating lever
