Instructions and safety instructions
This manual uses instructions and safety instructions for prevent-
ing injury and damage to property. To clearly identify them for
personnel, the instructions and safety instructions are distin-
guished as follows:
2.1.1. Instructions
Instructions are displayed in bold type. Instructions contain text
that refers to the previous text or particular sections, or highlights
short instructions.
2.1.2. Safety instructions
Safety instructions are slightly indented and displayed in bold
type. It always commences with a signal word.
Information that only refers to material damage is printed in grey,
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, dangerous electrical
voltage
Prohibition symbol, for example, Keep out!
Instruction symbol, for example, wear protective
clothing
The safety symbols used conform to the generally applicable
directives and regulations, such as DIN and ANSI.
Each safety instruction begins with one of the following signal
words:
•
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. Irreparable dam-
age is possible!
Safety instructions begin with a signal word and description of the
hazard, followed by its cause and potential consequences, and end
with advice on prevention.
2.2.
General safety information
• The electricity network must be switched off before any
work is performed (installation, dismantling, 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 im-
mediately by the operator.
• Tools and other objects should be kept in their designated
places.
• The switchgear may not be installed in potentially explo-
sive areas. A risk of explosions pertains.
These instructions must be strictly observed.
Non-observance can result in injury or substantial
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 operation,
pay attention to the permissible air humidity and
ensure the switchgear is installed so it is safe from
overflow.
The switchgears are operated with alternating or three-phase cur-
rent. 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 sup-
plied with power and how to cut off the supply. A residual-cur-
rent-operated protection switch (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 conductor at the earth
terminal indicated (
;
). The cross section of the cable for the pro-
tective ground conductor must correspond to the local regula-
tions.
If the switchgear has been switched off by a protec
-
tive 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 appli-
cable laws and regulations for work safety, accident prevention
and handling electrical 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.
