2.13.1 Attachment / change of the HBO 103 W/2 mercury pressure short-arc lamp
The illuminator N HBO 103 and the HBO 103 W/2 mercury pressure short-arc lamp are supplied to the
customer in separate packaging for safety reasons.
Therefore, insertion of the HBO 103 W/2 into the lamp housing is the first step in the start-up of the
illuminator.
Before opening the lamp housing, make sure that no connection to the electrical line is
available.
The HBO 203 W/2 lamps may only be changed after they have cooled down. Allow the
N HBO 103 microscope illuminator to cool down for approx. 15 minutes to avoid the risk of
explosion and burns.
The HBO 103 W/2 lamp may only be removed from the packaging and inserted in the
N HBO 103 illuminator if a protection mask and safety gloves are worn.
All electrical clamping connections must be made carefully. Pronounced heat during operation
may result in loose contacts.
For start-up or after expiry of the average
operation time of 300 h, the HBO 103 W/2
mercury vapor short-arc lamp must be inserted or
exchanged.
The operating time of the lamp can be read from
the counter (2-29/1) of the ebq 100 dc power
supply.
Follow the following steps when inserting /
changing the HBO 103 W/2 lamp:
• Pull off or unscrew line cable (near 2-29/2) and
N HBO 103 connector (near 2-29/3) from the
ebq 100 dc power supply.
• Wear protection mask and safety gloves.
