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.
