2.2. General safety information

• When installing or removing the waste water
pump station, never work alone in rooms and
shafts. A second person must always be present.
• The waste water pump station must always be
switched off before any work is performed on it
(assembly, dismantling, maintenance, instal-
lation). The electrical components must be
disconnected from the power supply and secured
against being switched on again. All rotating parts
must have come to a stop.
• The person operating the product must notify his
or her supervisor immediately should any defects
or irregularities occur.
• It is of vital importance that the system be shut
down immediately by the operator if any prob-
lems arise which may endanger safety of person-
nel. Problems of this kind include:
• Failure of the safety or control devices
• Damage to important parts
• Damage to electrical equipment, cables,
and insulation.
• Tools and other objects should be kept in a place
reserved for them so that they can be found
quickly.
• Sufficient ventilation must be provided in
enclosed rooms.
• When welding or working with electrical devices,
make sure there is no risk of explosion.
• Only use lashing equipment which is legally
defined as such and officially approved and
inspected regularly.
• The lashing equipment must be kept safely
and must be suitable for the conditions of use
(weather, hooking device, load, etc).
• Mobile equipment for lifting loads should be
used in such a way that it always remains stable
during operation.
• When using mobile equipment for lifting
non-guided loads, take action to prevent
t ipping, sliding, etc.
• Measures should be taken to ensure that no
person is ever directly beneath a suspended
load. Furthermore, it is also 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 (for example, if the
operator's field of vision is blocked).
• The load to be lifted must be transported in such
a manner that nobody can be injured in the event
of a power outage. Additionally, when working
outdoors, such procedures must be stopped
immediately if weather conditions worsen.
These instructions must be strictly observed.
Non‑observance can result in injury or substan-
tial material damage.

2.3. Directives used

The waste water pump station is subject to:
• Various EC directives
• Various harmonized standards
• Various national standards
28
See the EC Declaration of Conformity for precise
details of and the guidelines and standards used.
Also, various national standards are used as
a basis for operating, assembling and dismantling
the waste water pump station. These include the
German accident prevention regulations, VDE
regulations and German Equipment Safety Law.

2.4. CE marking

The CE marking is found either on or near the
name plate. The name plate is attached to the
collector tank or to the shaft access.

2.5. Electrical work

The electrical components are operated with
alternating or three-phase current. The local
regulations (e.g. VDE 0100) must be observed.
The "Electrical connection" section and the
electrical connection diagram for the particular
components must be observed when connecting
the product. The technical specifications must be
strictly adhered to.
If the waste water pump station has been
switched off by a protective device, it must
not be switched on again until the error has
been corrected.
ELECTRICAL hazard!
Incorrectly performed electrical work can
result in fatal injury! This work may only be
carried out by a qualified electrician.
BEWARE of moisture!
Moisture penetrating the cable will damage
both the electrical components and the cable.
Never immerse the cable end in fluid and always
protect it from moisture. Unused wires must be
insulated!

2.6. Electrical connection

The person operating the waste water pump sta-
tion must know where it is supplied with power
and how to cut off the supply. It is advisable to
install a residual current device (RCD).
The relevant national directives, standards and
regulations as well as the requirements of the
local public utility company must be observed.
When the electrical components are connected to
the electrical switching system, particularly when
electronic devices such as soft startup control or
frequency drives are used, the relay manufactur-
er's specifications must be followed to comply
with the electromagnetic compatibility (EMC)
requirements. Special separate shielding mea-
sures (e.g. shielded cables, cables laid separately,
filters) may be necessary for the power supply
and control cables.
The connections may only be made if the relays
meet the harmonized EU standards. Mobile
radio equipment may cause malfunctions in the
system.
