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qualied 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 overow-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specications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.
