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 safe from overflow.
Our switchgears are operated with alternating
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-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 ground conductor
at the ground terminal indicated (;). The cross
section of the cable for the protective ground
conductor must correspond to the local regula-
tions.
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.
Operation, display of operating state and signal-
ing is via pushbuttons and LEDs on the housing.
The housing cover must not be opened during
operation.
DANGEr due to electrical voltage
there is a risk of fatal electric shocks oc-
curring when performing work on the open
switchgear. only operate the switchgear with
the cover closed!

details of the guidelines and standards used.
Also, various national regulations are used as a
basis for operating, installation and dismantling
28
the switchgear. These include the German acci-
dent prevention regulations, VDE regulations and

3.1. Intended use and fields of application

DANGEr of explosions!
if the connected pump and signal transmitter
are used in potentially explosive areas, there
is a danger of fatal injuries from explosions!
the connected pump and signal transmitter
must always be used outside of potentially
explosive areas. installation must always be
carried out by a qualified electrician.
The MS-Lift switchgear is designed for
• automatic control of 1 pump without approval
for potentially explosive areas in lifting units and
sewage shafts for delivery of water/sewage.
The switchgear must not
• be used in potentially explosive areas.
• be overflowed.
Intended use also includes observation of these
instructions. Any other use is regarded as improp-
er.
NOTE
For automatic control, float switches must be
provided by the customer.
