The unit is grounded via the ground conductor integrated in the mains cable. This is an
important prerequisite for the safe operation of the unit. If the mains cable is correctly
connected in accordance with relevant electrotechnical regulations, proper grounding is
automatically ensured.
The yellow-and-green equipotential bonding cable is intended for use in cases where potential
equalization is required for laser operation (e.g. when using the Limax®60 for intracardiac
interventions).
3.13 Fuses
Defective fuses may be replaced only by authorized service personnel.
The fuses are installed on the rear panel of the unit. They include two line fuses located in the
mains connector socket assembly plus two overcurrent fuses (see section 5.5 “Rear Panel”,
page 30).
