2. Safety
This section lists all the generally applicable safety
information and technical instructions. In addition,
all the other sections contain specific safety infor -
mation and technical instructions. All instructions
and information must be observed and followed
during the various phases of the pump’s life cycle
(installation, operation, maintenance, transport,
etc.). The end user is responsible for ensuring that
all personnel follow these instructions and guide-
lines.
2.1. Instructions and safety information
This manual uses instructions and safety infor-
mation regarding possible injury and damage to
property. To identify them clearly for personnel, the
instructions and safety information are distin-
guished as follows:
• Instructions appear in bold and refer directly to the
preceding text or section.
• Safety information is slightly indented and bold and
always starts with a signal word.
• Danger
Serious or fatal injuries can occur!
• Warning
Serious injuries can occur!
• Caution

• Caution (instruction without symbol)
Substantial property damage can occur. Irrepa-
rable damage is possible!
• Note

• Safety information that refers to personal injury
appears in black and is always accompanied by a
safety symbol. Danger, prohibition, or instruction
symbols are used as safety symbols.
Example:
Danger symbol: General hazard
Danger symbol, for example, electrical current
Prohibition symbol, for example, Keep out!
Instruction symbol, for example, wear protective
clothing
The safety symbols used conform to generally ap-
plicable directives and regulations.
• Safety information that refers only to material dam-
age is printed in gray, without safety symbols.
2.2. General safety
• When installing or removing the pump, never work
alone in rooms or sumps. A second person must
always be present.
• The pump must always be switched off before any
work is performed on it (assembly, dismantling,
maintenance, installation). The pump must be dis-
connected 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 imme-
diately should any defects or irregularities occur.
• The operator must shut down the equipment im-
mediately if defects occur that represent a safety
risk. These include:
• Failure of the safety and/or monitoring devices
• Damage to important parts
• Damage to electrical equipment, cables, and
insulation.
• Tools and other objects should be kept in their des-
ignated places to ensure they can be used safely.
• Sufficient ventilation must be provided when work -
ing in enclosed rooms.
• When welding or working with electronic devices,
make sure there is no risk of explosion.
• Use only lifting gear which is legally defined as such
and officially approved.
• The lifting gear must be adapted to the conditions
of use (weather, guide system, load, etc.) and be
stored carefully.
• Mobile equipment for lifting loads should be used
in such a way that it is guaranteed to remain stable
during operation.
• When using mobile equipment for lifting non-guid-
ed loads, take action to prevent tipping, shifting,
sliding, etc.
• Take measures to prevent anyone standing under
suspended loads. Furthermore, it is prohibited to
move suspended loads over working areas occupied
by people.
• If using mobile operating equipment for lifting
loads, get a second person to coordinate the proce-
dure if necessary (e.g. blocked visibility).
• The load to be lifted must be transported in such
a way that no one will be injured if there is a power
failure. Furthermore, if such work is being carried
out outdoors, it must be canceled if the weather
conditions worsen.
