WARNING! or CAUTION! or REMEMBER! Applicable
to the given situation (general warning sign).
ATTENTION! Electric shock warning!
PLEASE NOTE! Drawings in this manual are for
illustration purposes only and in some details may
differ from the actual product.
The original operation manual is written in German. Other
language versions are translations from the German.
2. USAGE SAFETY
ATTENTION! Read all safety warnings and all
instructions. Failure to follow the warnings and
instructions may result in electric shock, fire and/or
serious injury or even death.
The terms "device" or "product" are used in the warnings
and instructions to refer to "Laboratory power supply".
Do not use in very humid environments or in the direct
vicinity of water tanks. Prevent the device from getting
wet. Risk of electric shock! Do not cover the ventilation
openings!
2.1. ELECTRICAL SAFETY
a)
The plug must fit the socket. Do not modify the
plug in any way. Using original plugs and matching
sockets reduces the risk of electric shock.
b)
Avoid touching earthed elements such as pipes,
heaters, boilers and refrigerators. There is an
increased risk of electric shock if the earthed device
is exposed to rain, comes into direct contact with a
wet surface or is operating in a damp environment.
Water getting into the device increases the risk of
damage to the device and of electric shock.
c)
Do not touch the device with wet or damp hands.
d)
Use the cable only for its designated use. Never use it
to carry the device or to pull the plug out of a socket.
Keep the cable away from heat sources, oil, sharp
edges or moving parts. Damaged or tangled cables
increase the risk of electric shock.
e)
If using the device in a damp environment cannot
be avoided, a residual current device (RCD) should
be applied. The use of an RCD reduces the risk of
electric shock.
f)
Please make sure that the device is properly earthed.
g)
Do not use the device if the power cord is damaged
or shows obvious signs of wear. A damaged power
cord should be replaced by a qualified electrician or
the manufacturer's service centre.
h)
When connecting the device, take precautions
against static electricity.
2.2. SAFETY IN THE WORKPLACE
a)
Make sure the workplace is clean and well lit. A
messy or poorly lit workplace may lead to accidents.
Try to think ahead, observe what is going on and use
common sense when working with the device.
b)
Do not use the device in a potentially explosive
environment, for example in the presence of
flammable liquids, gases or dust.

c)
If you discover damage or irregular operation,
immediately switch the device off and report it to a
supervisor without delay.
d)
If there are any doubts as to the correct operation
of the device, contact the manufacturer's support
service.
e)
Only the manufacturer's service point may repair the
device. Do not attempt any repairs independently!
f)
In case of fire, use a powder or carbon dioxide
) fire extinguisher (one intended for use on live
(CO
2
electrical devices) to put it out.
g)
Use the device in a well-ventilated space.
h)
Regularly inspect the condition of the safety labels. If
the labels are illegible, they must be replaced.
i)
Please keep this manual available for future
reference. If this device is passed on to a third party,
the manual must be passed on with it.
REMEMBER! When using the device, protect
children and other bystanders.

influence of alcohol, narcotics or medication which
can significantly impair the ability to operate the
device.
b)
The device is not designed to be handled by persons
(including children) with limited mental and sensory
functions or persons lacking relevant experience
and/or knowledge unless they are supervised by
a person responsible for their safety or they have
received instruction on how to operate the device.
c)
When working with the device, use common sense
and stay alert. Temporary loss of concentration while
using the device may lead to serious injuries.
d)
To prevent the device from accidentally switching on,
make sure the switch is on the OFF position before
connecting to a power source.
e)
The device is not a toy. Children must be supervised
to ensure that they do not play with the device.
2.4. SAFE DEVICE USE
a)
Do not overload the device. Use the appropriate
tools for the given task. A correctly-selected device
will perform the task for which it was designed better
and in a safer manner.
b)
Disconnect the device from the power supply
before commencement of adjustment, cleaning and
maintenance. Such a preventive measure reduces
the risk of accidental activation.
c)
When not in use, store in a safe place, away from
children and people not familiar with the device who
have not read the user manual. The device may pose
a hazard in the hands of inexperienced users.
d)
Keep the device in perfect technical condition.
Before each use check for general damage and
especially check for cracked parts or elements and
for any other conditions which may impact the safe
operation of the device. If damage is discovered,
hand over the device for repair before use.
e)
Keep the device out of the reach of children.
f)
Device repair or maintenance should be carried out
by qualified persons, only using original spare parts.
This will ensure safe use.
g)
To ensure the operational integrity of the device, do
not remove factory-fitted guards and do not loosen
any screws.
h)
When transporting and handling the device between
the warehouse and the destination, observe the
occupational health and safety principles for manual
transport operations which apply in the country
where the device will be used.
