SAFETY English
In addition, all the other sections contain specific
safety instructions and technical information.
All instructions and information must be ob -
served and followed during the various phases of
the switchgear 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 in-
structions for preventing injury and damage to
property. To clearly identify them for personnel,
the instructions and safety instructions are dis-
tinguished 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 (instruction without symbol)
Substantial property damage can occur. Irrepa-
rable damage is possible!
• Safety instructions that refer to personal injury
appear in black and are always accompanied by
a safety symbol. Danger, prohibition or instruc -
tion 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 protec -
tive clothing
The safety symbols used conform to the gener-
ally applicable directives and regulations, such
as DIN and ANSI.
• Safety instructions that only refer to materi-
al damage are printed in grey, without safety
symbols.
2.2. General safety
• The electricity network must be switched off
before any work is performed (installation, dis-
mantling, maintenance). The switchgear must be
disconnected from the electricity network and
secured against reactivation.
• The person operating the switchgear must notify
his or her supervisor immediately should any
faults or irregularities occur.
• Where damage occurs to electrical components,
cables and/or insulation, the switchgear must be
shut down immediately by the operator.
• Tools and other objects should be kept in their
designated places so that they can be found
quickly.
• The switchgear may not be installed in potentially
explosive areas. A risk of explosions pertains.
These instructions must be strictly observed.
Non-observance can result in injury or substan-
tial material damage.
2.3. Electrical work
DANGER due to electrical voltage!
Improper procedures during electrical work
may result in fatal injuries caused by electrical
voltage! Such work may only be carried out by
a qualified electrician.
BEWARE of moisture!
Ingress of moisture will result in damage to
the switchgear. During installation and oper-
ation, pay attention to the permissible air hu-
midity and ensure the switchgear is installed
so it is overflow-proof.
Our switchgears are operated with alternat-
ing or three-phase current. The governing
national directives, standards and regulations
(e.g. VDE 0100) as well as the requirements of the
local energy supply company must be observed.
The person operating the switchgear must know
where it is supplied with power and how to cut off
the supply. A residual-current device (RCD) must
be provided by the customer.
The section entitled "Electrical connection"
must be observed when connecting the product.
The technical specifications must be observed
strictly. The switchgear must always be grounded.
To do this, connect the protective earth conduc -
tor at the earth terminal indicated (
;
). The cross
section of the cable for the protective earth con-
ductor must correspond to the local regulations.
If the switchgear has been switched off by
a protective device, it must not be switched on
again until the fault has been corrected.
Use of electronic devices such as soft starters
or frequency converters is not possible with this
switchgear. Pumps must be connected directly.
2.4. Conduct during operation
When operating the switchgear, always follow the
locally applicable laws and regulations for work
safety, accident prevention and handling elec-
trical products. To help to ensure safe working
practice, the responsibilities of employees should
be clearly set out by the operator. All personnel
are responsible for ensuring that regulations are
observed.
