WARNING
Risk of injury due to electrical current and voltage!
Severe bodily injury or death can result! Therefore
please abide by the following:
·Do not touch bare, stripped wires or device inputs
that are dangerous to touch on the devices, com-
ponents and modules.
·Switch off your installation before commencing
work! Secure it against being switched on! Check
to be sure it is de-energized! Ground and short
circuit! Cover or block off adjacent live parts!
·During operation and troubleshooting, check the
environment for dangerous voltages and switch
these off if necessary!
·Wear protective clothing and protective equipment
in accordance with applicable guidelines when
working on electrical systems!
·Before making connections, ground the device /
component / module by means of the ground wire
connection, if present!
·Do not touching bare or stripped leads that are
energized! Equip stranded conductors with wire
ferrules!
·Hazardous voltages can be present in all circuitry
parts that are connected to the power supply.
·Protect wires, cables and devices with a suitable
line circuit breaker/fuse!
·Never switch off, remove or tamper with safety
devices!
·There can still be hazardous voltages present in
the device or in the component even after it has
been disconnected from the supply voltage. Check
to be sure it is de-energized!
·Do not operate equipment with current transformer
circuits when open.
·Only connect screw terminals with the same num-
ber of poles and design!
·Do not exceed the limit values specified in the user
manual and on the rating plate! This must also be
observed during testing and commissioning.
·Observe the safety and warning notices in the
usage information associated with the devices or
components!
2.4 Dangers when handling the device
When operating electric devices, components or
modules, it is unavoidable for certain parts of these
devices to conduct hazardous voltage. Consequent-
ly, severe bodily injury or material damage can occur
if they are not handled properly.
When handling the devices, always observe the
following:
·do not exceed the limit values specified in the user
manual and on the rating plate! This must also be
observed during testing and commissioning!
·Take note of the safety and warning notices in all
usage information that belongs to the device, com-
ponents or modules!
·Applicable laws, standards and regulations!
·The state of the art and current engineering prac-
tice at the point in time of installation.
2.5 Electrically qualified personnel
To avoid bodily injury and material damage, only
electrically qualified personnel are permitted to work
on the devices and their components, modules,
assemblies, systems and current circuits who have
knowledge of:
·The national and international accident prevention
regulations.
·Safety technology standards.
·Installation, commissioning, operation, disconnec-
tion, grounding and marking of electrical equip-
ment.
·The requirements concerning personal protective
equipment.
Electrically qualified persons within the scope of the
technical safety information of all usage information
associated with the device and its components are
persons who can furnish proof of qualification as an
electrically skilled person.
2.6 Warranty in the event of damage
Any unauthorized tampering with or use of the
device, component or module constitutes “misuse”
and/or “negligence” under the product’s warranty
and thus voids the warranty for any possible re-
sulting damage. In this regard, please take note of
section „6.3 Type-specific technical data - Designs“
on page 14.
