approved by the local electricity supplier only and in
accordance with local regulations.
• Disconnect the power supply before any work.

correspond to the details on the rating plate

VDE 0700/part 1 (CH: NIN 2010) via a fixed connecting cable,
which is provided with a plug device or an all-pole switch with
a contact opening width of at least 3 mm.
• Maximum back-up fuse: 10 A, slow-blow
• To ensure drip protection and strain relief at the PG screwed
connection, a connected load with an adequate outer diameter
is necessary (e.g. H05VV-F3G1.5).
• The connection line is to be installed in such a way that it can-
not under any circumstances come into contact with the pipe
and/or the pump and motor housing.
• Make the mains connection according to fig. 6.
• The connection cable can be taken through the cable feed-in right
or left. Exchange dummy plugs and cable feed-in as necessary.
