5. Electrical connection

The electrical connection must be made by an expert.
I.E.E. regulations must be complied with.
Please observe NIN (CENELEC) regulations.
In the case of higher water temperatures (over 80 °C), use an
appropriate heat-resistant connecting line.
The connecting line must not touch the piping, or the pump
and motor casings. In the case of twin pumps (series LXD ...),
a separate connecting line with all-pole switch is to be provided
for each pump motor (operating reliability!).
Be sure to provide protection against dripping water and a mains
lead cleat at the cable inlet to the connection box (gland)!
(rated current × 1.5) mx. 16 A, delay-action
Preliminary fuse:
Wire cross section: max. 2.5 mm
Starting current: max. 3 x rated current.
The electrical connection must be made in accordance with the
data plate. To simplify later replacement, the electrical connection
should be looped.
