SAF E TY
This chapter lists all the generally applicable safety instructions
and technical information. Furthermore, each remaining chap-
ter contains specific safety instructions and technical informa-
tion. All instructions and information must be observed and
followed during the various phases of the product's life cycle
(installation, operation, maintenance, transport etc.)! The opera-
tor is responsible for ensuring that personnel follow these
instructions and guidelines.
2.1
Instructions and safety information
This manual uses instructions and safety information for pre-
venting injury and damage to property. To uniquely identify
these for personnel, the instructions and safety information are
differentiated as follows:
2.1.1 Instructions
An instruction is displayed in "bold". Instructions contain text
that refers to the previous text or particular sections of chap-
ters, or highlights short instructions.
Example:
Note that products stored with drinking water must be
protected from frost!
2.1.2 Safety information
Safety information is slightly indented and displayed in "bold". It
always commences with a signal word.
Information that only refers to material damage is printed in
gray, without safety symbols.
Information that refers to personal injury is printed 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 the generally valid direc-
tives and regulations, such as DIN and ANSI.
Each safety instruction begins with one of the following signal
words:
- Danger
This can result in serious or fatal injuries!
- Warning
Serious injuries can occur!
- Caution
Injuries can occur!
- Caution (Instruction without symbol)
Substantial material damage can occur. Irreparable damage
is possible!
Safety instructions begin with a signal word and description of
the hazard, followed by the hazard source and potential conse-
quences, 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
