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:
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 6.4.12 of IEC 60079-11: 1999. This
must be taken into account during installation.
