1. Safety instructions
Pay attention to the instructions for use when handling the lamp.
WARNING:
This device has not been designed for use in potentially explosive areas.
According to the Medical Device Regulation the light is classified under class I.
Store the light in its package for at least 24 hours in the respective room before mounting,
in order to equal temperature differences.
Please read the instructions for use carefully to make the most of your lighting system and
to avoid any damages to the device.
The lights may only be repaired and special assembly work may only be carried out by
ourselves or a company that has been expressly authorized by us.
The manufacturer can only be made responsible for the safety of the light if repairs and al-
terations are carried out by the manufacturer himself or a company that guarantees to ob-
serve the safety regulations.
No modification of the lamp is allowed!
The manufacturer cannot be made liable for personal or material damages if the light is
operated inexpediently or incorrectly or used for purposes other than those for which it is
intended.
The light is to be dismantled from the spring arm in reverse order to its assembly. This
may only be carried out after the spring arm has been adjusted in height at horizontal po-
sition since the arm is under spring tension and can bounce up.
Make sure that the light is in perfect working order before every use.
Attention, external power supply!
The light works only with an external power supply 60VA.
The external power supply used with the light must be tested and validated according to
IEC 60601-1.
Attention!
A main control switch must be installed for turning the system power-off. The switch must
meet the requirements of the standard IEC 61058-1 regarding rated voltage peaks of
4kV.
During the mounting of the lights the entire system (incl. the ceiling attachment) must be dis-
connected from mains!
A later dismounting of the lights from the spring arms or dismounting the sliding contacts in-
side the arms is to be done ONLY AFTER DISCONNECTING THE ENTIRE SYSTEM FROM
MAINS.
Otherwise the electronic board will be damaged!

2. Exchanging the protective glass
Failure description: The protective glass of the light can become dull in time or can be
scratched. As a result the light efficiency decreases. In such cases we recommend the ex-
change of the protection glass. The part number is 32035201.
Turn off the light and position it like shown in the picture.
Loosen and remove the seven marked fixation screws (pos. 1) with a crosshead screw-
driver and remove the damaged protection glass.
Mount the new protection glass (Pos. 2) in reverse order:
First of all remove the protective foil at the inner side.
Please observe the correct position: the recess in the protective glass must match with
the nose in the lamp housing, see detail!
Fix the protective glass with seven screws, part number 65872004 DIN 7982 2,2x9,5 and
then remove the protective foil at the outer side of the protective glass.
