DANGER!
Contact with live parts is dangerous to life!
y The voltage taps are not fused within the meter and are directly
connected to the mains potential.
y Protect meters with a transformer connection in the voltage circuit
with a back-up fuse of ≤ 6 A.

DANGER!
Risk of danger to life due to high voltage when current transform-
ers are interrupted!
The high voltage on the interrupted current transformer at the trans-
former connected meter is extremely dangerous and destroys the
current transformer.
y Short-circuit the secondary circuits of the current transformer at the
testing terminals before disconnecting the current path.
