Safety instructions for all DEWETRON systems
The DEWETRON data acquisition systems may only be installed by experts.
Read your manual before operating the system.
Observe local laws when using the instrument.
Ground the equipment: For Safety Class 1 equipment (equipment having a protective earth terminal),
a non interruptible safety earth ground must be provided from the mains power source to the product
input wiring terminals or supplied power cable.
DO NOT operate the product in an explosive atmosphere or in the presence of ammable gases or
fumes and do not bring the system in contact with water.
DO NOT operate damaged equipment: Whenever it is possible that the safety protection features built
into this product have been impaired, either through physical damage, excessive moisture, or any
other reason, REMOVE POWER and do not use the product until safe operation can be veried by
service-trained personnel. If necessary, return the product to a DEWETRON sales and service ofce
for service and repair to ensure that safety features are maintained.
Keep away from live circuits: Operating personnel must not remove equipment covers or shields.
Procedures involving the removal of covers or shields are for use by service-trained personnel only.
Under certain conditions, dangerous voltages may exist even with the equipment switched off. To
avoid dangerous electrical shock, DO NOT perform procedures involving cover or shield removal
unless you are qualied to do so.
No modications are allowed at the instrument. The fuse in the power module has to be replaced by
the same type. For continued protection against re, replace the line fuse(s) only with fuse(s) of the
same voltage and current rating and type. DO NOT use repaired fuses or short-circuited fuse holder
labels and print on the power module may not be removed.
DO NOT service or adjust alone. Do not attempt internal service or adjustment unless another person,
capable of rendering rst aid and resuscitation, is present.
DO NOT substitute parts or modify equipment: Because of the danger of introducing additional
hazards, do not install substitute parts or perform any unauthorized modication to the product. Return
the product to a DEWETRON sales and service ofce for service and repair to ensure that safety
features are maintained.
Before opening the instrument (experts only) or exchanging the fuse in the power module disconnect
power!
Don’t touch internal wiring!
Don’t use higher supply voltage than specied and take care of the correct polarity, otherwise the
system will be damaged!
Use only original plugs and cables for harnessing.
Install ller-panels in unused slots.
The power-cable and -connector serve as Power-Breaker. The cable must not exceed 10 feet,
disconnect function must be possible without tools.
Keep the ventilation slots free and check them frequently to avoid an overheating of the system. The
cleaning interval of the lter pads depends on the environmental conditions.
Safety of the operator and the unit depend on following these rules.
DEWETRON is not responsible for any damage or injury that could result from improper connection or
misuse!

CAUTION
The system BIOS is protected by password. Any change in the BIOS may cause a system crash.
When the system is booting, do not press ESC-button on keyboard. This may clear the BIOS settings
and cause system faults.
Any change in the le structure as deleting or adding les or directories might cause a system crash.
Before installing software updates contact DEWETRON or your local distributor. Use only software
packages which are released by DEWETRON. Further informations are also available in the internet
(http://www.dewetron.com).
After power off the system wait at least 10 seconds before switching the system on again. Otherwise
the system may not boot correct. This prolongs also the life of all system components.
