source and potential consequences, and end with
advice on prevention.
Example:
Beware of rotating parts!
The rotating rotor can crush and sever limbs.
Switch off the product and let the rotor come to
a stop.
2.2 General safety
• When installing or removing the product, never work
alone in rooms and shafts. A second person must
always be present.
• The product must always be switched off before any
work is performed on it (assembly, dismantling, main-
tenance, installation). The product must be discon-
nected from the electrical system and secured against
being switched on again. All rotating parts must have
come to a stop.
• The operator should inform his/her superior immedi-
ately should any defects or irregularities occur.
• It is of vital importance that the system be shut down
immediately by the operator if any problems arise
which may endanger safety of personnel. Problems of
this kind include:
• Failure of the safety and/or control devices
• Damage to important parts
• Damage to electric installations, cables, and insula-
tion.
• Tools and other objects should be kept in a place
reserved for them so that they can be found quickly.
• Sufficient ventilation must be provided in enclosed
rooms.
• When welding or working with electronic devices,
ensure that there is no danger of explosion.
• Only use fastening devices which are legally defined as
such and officially approved.
• The fastening devices should be kept safely and must
be suitable for the conditions of use (weather, hook-
ing system, load, etc).
• Mobile working apparatus for lifting loads should be
used in a manner that ensures their support stability
during operation.
• When using mobile working apparatus for lifting non-
guided loads, preventive measures should be taken to
avoid tipping and sliding etc.
• Measures should be taken to ensure that no person is
ever directly beneath a suspended load. Furthermore,
it is also prohibited to move suspended loads over
workplaces where people are present.
• If a mobile working apparatus is used for lifting loads, a
second person should be present to coordinate the
procedure, if required (for example, if the operator’s
field of vision is blocked).
• The load to be lifted must be transported in such a
manner that nobody can be injured in the case of a
power outage. Additionally, when working outdoors,
such procedures must be interrupted immediately if
weather conditions worsen.
These instructions must be strictly observed.
Non-observance can result in injury or substan-
tial material damage.
2.3 Directives used
This product is subject
• various EC directives
• various harmonized standards
• and various national standards.
Please consult the EU Declaration of Conformity for
the precise information and the guidelines and norms
in effect.
Also, various national standards are also used as a basis
for using, assembling and dismantling the product.
These include the German accident prevention regula-
tions, VDE regulations, German Equipment Safety Law
etc.
2.4 CE marking
The CE marking is found either on the type plate or
near the type plate. The type plate is attached to the
motor casing or to the frame.
2.5 Electrical work
Our electrical products are operated with alternating or
three-phase current. The local regulations (e.g. VDE
0100) must be observed. The chapter entitled “Electri-
cal connection” must be observed when connecting
the product. The technical specifications must be
strictly adhered to!
If the product has been switched off by a protec-
tive device, it must not be switched on again
until the error has been corrected.
2.6 Electrical connection
The operator is required to know where the machine is
supplied with current and how to cut off the supply.
The installation of an earth leakage circuit breaker
(RCD) is recommended.
The governing national directives, standards and regu-
lations as well as the requirements of the local public
utility company must be observed.
When the product is connected to the electrical con-
trol panel, particularly when electronic devices such as
soft startup control or frequency drives are used, the
relay manufacturer's specifications must be followed
to comply with the electromagnetic compatibility
(EMC) requirements. Special separate shielding mea-
sures (e.g. shielded cables, filters, etc.) may be neces-
sary for the power supply and control cables.
The connections may only be made if the relays
meet the harmonized EU standards. Mobile radio
Beware of electrical current!
Incorrectly performed electrical work can result
in fatal injury! This work may only be carried out
by a qualified electrician.
Beware of moisture!
Moisture penetrating the cable damages both
the product and cable. Never immerse cable
ends in the pumped liquid or other liquids.
Unused wires must be insulated!
