1 Notes on Safety
1.1 General
Please make yourself familiar with the contents
of these operating instructions before attaching
and starting up the N HBO 103 and N XBO 75
microscope illuminators. Additional information
is available from our maintenance service or
from authorized agencies.
The N HBO 103 and N XBO 75 microscope
illuminators should be used with Zeiss
microscopes exclusively.
The N HBO 103 and N XBO 75 microscope
illuminators may only be handled by trained
personnel.
To ensure that the illuminators function
properly with the microscope, the appropriate
microscope manual must be observed.
The manuals
"ebq 100 dc – Electronic transformer for the N
HBO 103 microscope illuminator“ and
"ebx 75 isolated – Electronic transformer for
the N XBO 75 microscope illuminator“
must be observed.
Special regard must be paid to the notes on
instrument safety included in this manual.
The data sheets from the lamp manufacturers
must be observed when the HBO 103 and XBO
75 lamps are operated.
To guarantee the safe operation and function
of the N HBO 103 and N XBO 75 microscope
illuminators, it is necessary under any
circumstances to take the precaution measures
and observe the warnings contained in the
operating instructions.
The following symbols are used for the
warnings:
CAUTION!
Non-observance of the safety notes constitutes
a hazard for the user.
CAUTION!
Dangerous electrical voltage
CAUTION!
Disconnect the instrument from the line before
opening it!
CAUTION!
Hot surface
CAUTION!
Non-observance of the safety notes constitutes
the risk of damage to the instrument.
☞NOTE!
Notes which must be observed when using the
N HBO 103 and N XBO 75 microscope
illuminators.
1.2 Regulations concerning
Instrument Safety and
Electromagnetic
Compatibility (EMC)
The N HBO 103 and N XBO 75 microscope
illuminators have been designed and tested in
compliance with EN 61010, Part 1 (VDE 0411).
From the safety viewpoint, they left the factory
in a perfect state.
They meet the requirements of EC directives
73/23 and 89/336 and the EMC legislation,
version of Nov.9, 1992.
Radio-screened in accordance with EN 55011,
Class B, insensitivity to noise in accordance with
EN 50082-2.
Compliance with the EC directives mentioned is
documented by the CE-certificate.

Microscope Illuminating Systems Notes on unpacking, transport, storage and use Carl Zeiss
B 40-065 e 08/99 5
1.3 Notes on Unpacking,
Transport and Storage
The lamps, especially the XBO 75, are under
high pressure even if they are not switched on.
They may therefore be removed from the
package only if the protection mask (Cat.No.
417009) and the safety gloves with artery
protection (Cat. No. 417008) are worn.
The XBO 75 has an additional plastic protection
sleeve which must not be removed when the
lamp is unpacked!
For safety reasons, a safety holder is inserted in
the microscope illuminator instead of the bulb
during transport.
Both the N HBO 103 and N XBO 75 microscope
illuminators and the HBO 103 and XBO 75
lamps must be transported in their original
packaging.
This packaging and the plastic protection sleeve
of the XBO 75 must be kept for storage and
disposal.
The transport and storage temperatures must
be observed in the same way as those of the
microscope stands.
1.4 Hints on Use
−The lamps, especially the XBO 75, are under
high pressure even if they are not switched
on.
They may only be inserted in the microscope
illuminator if a safety mask and safety gloves
(see chapter 1.3) are worn.
The safety regulations of the lamp
manufacturer must be observed when the
XBO 75 is inserted.
−The HBO 103 and XBO 75 lamps are under
high pressure during operation; they must
always be opereated in closed lamp
housings!
−The light of the HBO 103 and XBO 75 short-
arc lamps contains a high amount of UV
light:
 Never look directly into the lamp or in
reflected light
 Wear safety glasses (sunglasses) when
operating the lamps
 Cover inspection openings with filters
−The UV radiation of the lamps produces
harmful ozone.
This gas must be carried off to the outside
via exhauster tubes and the working room
supplied with fresh air.
−Both the N HBO 103 and N XBO 75
microscope illuminators and the HBO 103
and XBO 75 lamps must be protected from
impact and humidity.
☞
Instead of the HBO 103, its predecessor HBO
100 can also be used.

1.5 Hints on Maintenance and
Care
To enable the microscope illuminators to
function perfectly, it is necessary to use only
components and spares marketed or admitted
by us. When in doubt, please contact our
service staff.
With the exception of the work described in
this manual, the user must not perform any
repairs or changes himself.
We would like to emphasize that all other
changes and repairs must be performed by
specially authorized personnel.
Defective instruments or components may only
be repaired and maintained by our service
department.
−After expiry of the average operating time
(see data sheets from the lamp
manufacturers), the lamps must be
exchanged; there is a risk of explosion!
The operating time of the HBO 103 and XBO
75 can be checked on the counter of the
relevant transformer.
(Fig. 5/Fig. 8)
The intensity of the lamps decreases when
the operating time increases, i.e.
homogeneous illumination of the object field
can then no longer be guaranteed.
−The lamps must be exchanged as described
in chapters 3.1/3.2.
−Before each lamp exchange, make sure to
allow the N HBO 103 or N XBO 75
microscope illuminator to cool down
sufficiently long in order to reduce the
pressure; wait at least for 15 minutes!
−Always disconnect the instrument from the
line before each lamp exchange or any other
work inside the instrument.
−The safety regulations of the lamp
manufacturer must be observed when the
XBO 75 is changed.
−Check the cables of the N HBO 103 and N
XBO 75 when changing the lamp.
−Clean the housing of the microscope
illuminator when it is dirty.
Do not use any solvents.
Soak a cleaning cloth in a mixture of water
and washing-up liquid, remove the dirt and
dry the housing using a clean cloth.
1.6 Hints on Disposal
Used HBO 103 and XBO 75 lamps and defective
microscope illuminators should not be treated
like domestic waste; they should be disposed of
in their original packaging in accordance with
the legal regulations.
When in doubt, please contact the Carl Zeiss
microscopy service.
1.7 Hints on Warranty
The instrument manufacturer is not liable for
damage caused by unauthorized operation,
particularly the removal and exchange of
components, or the use of accessories from
other manufacturers. This forfeits all the claims
against warranty.
