- 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 electronic devices, ensure that
there is no danger of explosion.
- Only use fastening devices which are legally defined as such
and officially approved.
- The fastening devices should be kept safely and must be
suitable for the conditions of use (weather, hooking system,
load, etc).
- Mobile working apparatus for lifting loads should be used in a
manner that ensures their support stability during operation.
- When using mobile working apparatus for lifting non-guided
loads, preventive measures should be taken to avoid tipping
and 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 a mobile working apparatus is used for lifting loads, a sec-
ond 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 case of a power outage.
Additionally, when working outdoors, such procedures must
be interrupted immediately if weather conditions worsen.
These instructions must be strictly observed. Non-
observance can result in injury or substantial material
damage.
2.3
Directives used
This product is subject
- various EC directives
- various harmonized standards
- and various national standards.
Please consult the EU Declaration of Conformity for the precise
information and the guidelines and norms in effect.
Also, various national standards are also used as a basis for
using, assembling and dismantling the product. These include
the German accident prevention regulations, VDE regulations,
German Equipment Safety Law etc.
2.4
CE marking
The CE marking is found either on the type plate or near the
type plate. The type plate is attached to the motor casing or to
the frame.
2.5
Electrical work
Our electrical products are operated with alternating or three-
phase current. The local regulations (e.g. VDE 0100) must be
observed. The chapter entitled "Electrical connection" must be
observed when connecting the product. The technical specifi-
cations must be strictly adhered to!
If the product has been switched off by a protective
device, it must not be switched on again until the error
has been corrected.
Beware of electrical current!
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 damages
both the product and cable. Never immerse
cable ends in the pumped liquid or other liq-
uids. Unused wires must be insulated!
2.6
Electrical connection
The operator is required to know where the machine is sup-
plied with current and how to cut off the supply. The installation
of an earth leakage circuit breaker (RCD) is recommended.
The governing national directives, standards and regulations as
well as the requirements of the local public utility company must
be observed.
When the product is connected to the electrical control panel,
particularly when electronic devices such as soft startup con-
trol or frequency drives are used, the relay manufacturer's spec-
ifications must be followed to comply with the electromagnetic
compatibility (EMC) requirements. Special separate shielding
measures (e.g. shielded cables, filters, etc.) 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.
Beware of electromagnetic radiation!
Electromagnetic radiation can pose a fatal
risk for people with pacemakers. Put up
appropriate signs and make sure anyone
affected is aware of the danger!
2.7
Ground connection
Our products (unit including protective devices and control sta-
tion, auxiliary hoisting gear) must always be grounded. If there is
a possibility that people can come into contact with the prod-
uct and the pumped liquid (e.g. at construction sites), the con-
nection must be additionally equipped with an earth leakage
protection device.
The pump units are submersible and conform to pro-
tection class IP 68 in terms of the applicable stan-
dards.
The protection class of the installed switching devices
can be found on the device housing and correspond-
ing operation manual.
2.8
Safety and monitoring devices
Our products can be equipped with mechanical (e.g. intake
strainer) and/or electrical (e.g., thermo sensors, moisture sen-
sors, etc.) safety and monitoring devices. These devices must
be attached or connected.
Electrical devices such as thermo sensors, float switches, etc.
must be connected and checked by an electrician for proper
functioning before start-up.
