Operating Precautions
• Do not input a current in excess of the maximum allowable
current. Doing so may damage the instrument or cause burns.
The maximum allowable current is 100 A AC continuous or
200 A AC within 2 minutes at 50 Hz/60 Hz. For more informa-
tion about the frequency derating characteristics during con-
tinuous input, see the following diagram:
• To avoid damage to the instrument, protect it from physical
shock when transporting and handling. Be especially careful
to avoid physical shock from dropping.
• Be careful to avoid dropping the instrument or otherwise sub-
jecting them to mechanical shock, which could damage the
mating surfaces of the core and adversely affect measure-
ment.
• Although this instrument is dust resistant, it is not completely
dust- or waterproof. To prevent possible damage, avoid using
in dusty or wet environments.
• Do not slant the instrument or place it on top of an uneven sur-
face. Dropping or knocking down the instrument can cause
injury or damage to the instrument.
