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)
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.
f) ATTENTION! DANGER TO LIFE! While cleaning,
never immerse the device in water or other liquids.
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. The device
generates sparks which may ignite dust or fumes.
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
(CO
2
) fire extinguisher (one intended for
use on live electrical devices) to put it out.
g)
Regularly inspect the condition of the safety labels.
If the labels are illegible, they must be replaced.
h) 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.
i)
Keep the device away from children and animals.
j) If this device is used together with
another equipment, the remaining
instructions for use shall also be followed.
To increase the product life of the device and to ensure
trouble-free operation, use it in accordance with this user
manual and regularly perform maintenance tasks. The
technical data and specifications in this user manual are
up to date. The manufacturer reserves the right to make
changes associated with quality improvement.

1. GENERAL DESCRIPTION
The user manual is designed to assist in the safe and
trouble-free use of the device. The product is designed
and manufactured in accordance with strict technical
guidelines, using state-of-the-art technologies and
components. Additionally, it is produced in compliance
with the most stringent quality standards.
DO NOT USE THE DEVICE UNLESS YOU HAVE
THOROUGHLY READ AND UNDERSTOOD THIS
USER MANUAL.
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 with
USB LAN>. 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 air inlets/
outlets!
REMEMBER!
When using the device, protect
children and other bystanders.
2.3. PERSONAL SAFETY
a)
Do not use the device when tired, ill or under the
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)
To prevent the device from accidentally switching on,
make sure the switch is on the OFF position before
connecting to a power source.
d)
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.
b)
Do not use the device if the ON/OFF switch does not
function properly (does not switch the device on and
off). Devices which cannot be switched on and off
using the ON/OFF switch are hazardous, should not
be operated and must be repaired.
c) Disconnect the device from the power supply
before commencement of adjustment, cleaning and
maintenance. Such a preventive measure reduces
the risk of accidental activation.
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) Avoid situations where the device stops working
during use due to excessive loading. This may result
in overheating of the drive elements and damage to
the device.
i)
Clean the device regularly to prevent stubborn grime
from accumulating.
j)
It is forbidden to interfere with the structure of
the device in order to change its parameters or
construction.
k)
Keep the device away from sources of fire and heat.
l)
Use the device at altitude not exceeding 2,000 m
above sea level.
m) Do not use the power supply under a maximum load
for extended periods.
n)
Do not short live leads.
o)
Use larger cross section leads for serial and parallel
connections, to accommodate the achieved current
and voltage.
p) Disconnect external load leads before changing
power supply operating mode.
ATTENTION!
Despite the safe design of the device
and its protective features, and despite the use of
additional elements protecting the operator, there is
still a slight risk of accident or injury when using the
device. Stay alert and use common sense when using
the device.
