NOTE

1.The external circuit contains no combined lumped inductance and capacitance greater than 1% of the above values.

Or 2. The inductance and capacitance are distributed as in a cable.

Or 3. The external circuit contains only lumped inductance or only lumped capacitance in combination with a cable.

In all other situations e.g. combined lumped inductance and capacitance, up to 50% of each of L and C values is allowed.

Conditions of Certification (X):

When fitted with the transient option, the apparatus is not capable of withstanding the 500V electrical strength test as defined in Clause 6.3.12 of IEC 60079-11. This must be taken into account during installation.
