INSTRUCTIONS FOR USE SUPPORTS AND STANDS
An equipotential bonding cable is an additional conductor (accessory; not included in the scope of delivery), which
establishes a direct connection between the electrical device and the potential equalising bus bar of the electrical
installation. The mobile light on the mobile stand as well as the wall-mounted lights have an equipotential bon-
ding connector on the housing of the mobile stand or on the wall mounting so that possible differences in voltage
which can occur as voltage sources, are avoided in the patient environment; also in connection with the parallel
use of other devices. Such voltage sources can cause currents over the body resistance, which not only fl ow over
the patient but can also affect doctors and nurses or even endanger them. Currents fl owing through such active
medical devices can lead to malfunctions.
In rooms used for Class 2 medical purposes, all external conductive parts within the patient environment are (elec-
trically connected with each other and) connected to the earthing conductor busbar in addition to the protective
measures according to DIN VDE 0100 Part 410. This means protective bonding conductors must be connected to a
potential equalizing busbar.
In particular when using the lights in connection with critical procedures such as e.g. examinations near the heart
and procedures to the heart, it must be ensured that the value for the maximum permissible contact voltages of
10 mV is not exceeded (∆u ≤ 10mV). On the side of the lights, this is supported e.g. by the existing equipotential
bonding connector in connection with the equipotential bonding conductor (see accessories).
In ceiling-mounted lamps, a protective bonding conductor must be connected for installation in medical rooms of
Class 2 with the respective ceiling slabs, as listed in the corresponding instructions for installation.
