Operations sequence
The driving mechanism is manual and drives a two-position
disconnector housed inside the gas tank. The mechanism
has two positions: closed and opened (or earthed).
Use the following operations sequence to disconnect the
voltage transformer disconnector:
1. Move the locking lever down as far as it will go to
release the mechanism.
