Electrical connection
DANGER: Work on the electrical connection must be
performed only by a qualified electrician and in accor-
dance with national and local regulations.
Before making the connection, ensure that the con-
necting cable is not live.
• The mains voltage and current type must correspond to the
rating plate specifications.
• Connect the plug (Fig. 4a to 4e).
• Mains connection: L, N, PE.
• Max. back-up fuse: 10 A, slow-blow.
• Earth the pump in accordance with instructions.
Dismantle the plug in accordance with Fig. 5. A screwdriver
is required to do this.
• The electrical connection is to be established via a fixed con-
necting cable equipped with a connector device or an all-
pole switch with a contact opening width of at least 3 mm.
• To ensure drip protection and strain relief at the PG
screwed connection, a connecting cable with an adequate
outer diameter is required (e.g. H05VV-F3G1.5).
• For pumps in systems with water temperatures above
90 °C, install a suitably heat-resistant connecting cable.
