5.3. Connecting instruments

Before connecting instruments, ensure that the following conditions
are met:

Combinations of accessories not mentioned in the
operating manual may be used only if they are explicitly
designed for the intended use. Performance features as
well as safety requirements must always be taken into
account.

The insulation of the accessories (e.g. HF cables,
instruments) must be sufficient for the maximum output
peak voltage (see IEC 60601-2-2 and IEC 60601-2-18).

Do not use accessories with defective insulation.
