The capacitance and either the Inductance or the Inductance to Resistance Ratio (L/R)
of the load connected to the 4-pin connector must not exceed the following values:
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.
