Safety Information
0 Important Safety Information
0.1 Electrical hazards
1 The electrical connection must only be provided by
a trained person. Please observe the national regu-
lations in the country of use like EN 50110-1 for
Europe, for example.
2 Lethal voltages are present at the mains connec-
tions. Before starting with any maintenance and
service work, de-energise (lockout/tagout) the prod-
uct first.
3 Unauthorized device conversion and modifications
are prohibited for safety reasons.
4 Lay connecting lines so that they cannot be dam-
aged. Protect the lines against humidity and contact
with water. Avoid any heat stress on the line due to
unfavourable laying conditions.
5 Suitably support the connecting lines so that the
pumps are not exposed to any major mechanical
stress.
6 Do not expose the display unit and the connections
to dripping water. Note the information on the IP
type of protection.
7 When storing the display unit 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 insula-
tion levels of electrical components
8 Transport the display unit 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.
9 Make the electrical connections only after pump
and accessories (e.g. air cooler) have been installed
mechanically.
