SAFETY English
cal information. All instructions and information must be
observed and followed during the various phases of the
hydraulics’s life cycle (installation, operation, maintenance,
transport etc.)! The operator is responsible for ensuring that
all personnel follow these instructions and guidelines.
2.1.
Instructions and safety instructions
This manual uses instructions and safety instructions for
preventing personal injury and material damage. To clearly
identify them for personnel, the instructions and safety
instructions are distinguished as follows:
• Instructions appear in “bold” and refer directly to the
preceding text or section.
• Safety instructions are slightly “indented and bold” and
always start with a signal word.
•
Danger
Serious or fatal injuries can occur!
•
Warning
Serious injuries can occur!
•
Caution
Injuries can occur!
•
Caution
(notice without symbol)
Substantial material damage can occur. Irreparable
damage is possible!
• Safety instructions that refer to personal injury appear
in black and are always accompanied by a safety symbol.
Danger, prohibition or instruction symbols are used as
safety symbols. Example:
Danger symbol: General hazard
Danger symbol, e.g. electrical current
Symbol for prohibited action, e.g. “No entry!”
Instruction symbol, e.g. “Wear protective cloth-
ing.”
The safety symbols used conform to the generally applicable
directives and regulations, such as DIN, ANSI.
• Safety instructions that only refer to material damage
are printed in grey, without safety symbols.
2.2.
General safety information
• When installing or removing the hydraulics, never work
alone in rooms and sump. A second person must always
be present.
• The hydraulics must always be switched off before any
work is performed on it (assembly, dismantling, main-
tenance, installation). The drive for the hydraulics must
be disconnected from the electrical system and secured
against being switched on again. All rotating parts must
have come to a standstill.
• The operator must report any faults or irregularities that
occur to a line manager immediately.
• The operator must shut down the equipment immedi-
ately 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 insula-
tion.
• Tools and other objects should only be kept in their des-
ignated places so that safe operation is ensured.
•
Sufficient ventilation must be provided when working in
enclosed spaces.
• When welding and/or working with electrical devices,
make sure there is no risk of explosion.
• Only use lifting gear which is legally designated as such
and officially approved.
• The lifting gear must be kept safely and must be suitable
for the conditions of use (weather, hooking unit, load,
etc.).
• 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-guided
loads, take action to prevent tipping, shifting, sliding etc.
• Measures should be taken to ensure that no person is
ever directly beneath a suspended load. Furthermore, it
is prohibited to move suspended loads over workplaces
where people are present.
• If mobile equipment is used for lifting loads, a second
person should be present to coordinate the procedure if
required (e.g. if the operator’s field of vision is blocked).
• The load to be lifted must be transported so that no-one
will be injured if there is a power failure. Furthermore,
if such work is being performed outdoors, it must be
cancelled if the weather conditions worsen.
These instructions must be strictly observed. Non-
observance can result in personal injury and/or substantial
material damage.
2.3.
Drive
The hydraulics has a standardised connection flange for
installing an IEC standard motor. See the technical data for
the performance data (e.g. size, construction, hydraulic rated
power, speed) needed to select a motor.
2.4.
Electrical work
DANGER due to electrical current!
Incorrectly performed electrical work can
result in fatal injury! This work may only be
carried out by a qualified electrician.
The motor must be connected in accordance with the infor-
mation in the operating and maintenance manual for the
motor. The governing local directives, standards and regula-
tions (e.g. VDE 0100) as well as the requirements of the local
energy supply company must be observed.
The person operating the motor must know where it is
supplied with power and how to cut off the supply. A motor
protection switch must be installed on-site. It is advisable to
install a residual-current device (RCD). If there is a possibility
that people can come into contact with the motor and the
fluid, the connection
must
be equipped with an additional
residual-current device (RCD).
