0.2 Electrical hazards
1
The electrical connection must only be provided by a trained person.
Please observe the national regulations in the country of use like EN
50110-1 for Europe, for example.
2
Lethal voltages are present at the mains connections. Before starting
with any maintenance and service work, de-energise (lockout/tagout)
the product first.
3
Unplug any connectors only when the mains voltage is switched off
and the pump does no longer turn
4
At speeds approximately below 200 Hz, there will not be enough
power any more for the LEDs, i.e. the pump may still turn with out any
of the LEDs being on.
5
Unauthorized device conversion and modifications are prohibited for
safety reasons.
6
Hazardous voltages are present within the frequency converter. When
coming into contact with these, death or severe injury can result. After
the pump has arrived at standstill, disconnect the frequency converter
from the mains power and prevent it against being switched on inad-
vertently (lockout/tagout) before opening it. Basically there is no reason
why the frequency converter should be opened. There are no user ser-
viceable parts inside.
Should, even so, changes be made to the pump-frequency converter
system then a trained electrician, as specified by the standard
EN 50110-1, for example, must perform an electrical safety test again
in accordance with the locally applicable safety regulations.
7
Lay connecting lines so that they cannot be damaged. Protect the
lines against humidity and contact with water. Avoid any heat stress on
the line due to unfavourable laying conditions.
8
Suitably support the connecting lines so that the pumps are not
exposed to any major mechanical stress.
9
Do not expose pump, frequency converter and the connections to
dripping water. Note the information on the IP type of protection.
10
When storing pump, frequency converter and connecting lines in a
humid atmosphere, these can suffer corrosion. Corrosion gives rise to
conductive deposits which in turn can cause short-circuits and reduce
the insulation levels of electrical components
11
Transport pump, frequency converter and connecting cables only in
their original packaging so as to avoid any mechanical damage which
in turn may reduce air gaps and creepage distances.
12
When applying external voltages above 42 V to the connection termi-
nals, observe the applicable VDE safety regulations!
13
Make the electrical connections only after pump and accessories (e.g.
air cooler) have been installed mechanically
