Safety information
Warning!
Never disconnect a secondary connection of current transformer circuit without short-
circuiting the transformer's secondary winding. Operating a current transformer with
the secondary winding open will cause a massive potential build-up that may damage
the transformer and may cause injuries to humans.
Warning!
Never unmount the front or back cover from a powered terminal or from a terminal con-
nected to powered circuitry. Potentially lethal voltages and currents are present.
