Electrical connection

DANGER: Work on the electrical connection may only
be performed by a qualified electrician in accordance
with national and local regulations.
Before establishing the connection, make sure that the
connecting cable is dead.
• Mains voltage and current type have to 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.
• Earth the pump according to the regulations.
Dismantle the plug in accordance with Fig. 5. A screwdriver
is needed for this.
• The electrical connection is to be established via a fixed
connection line 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 connected load with an adequate
outer diameter is necessary (e.g. H05VV-F3G1.5 or
AVMH-3x1.5).
• When pumps are used in systems with water temperatures
above 90°C, a suitably heat-resistant connected load is
installed.
• The connected load is to be placed in such a way that it can
under no circumstances come into contact with the pipe
and/or the pump and motor housing.
• The switching of the pump via triacs/solid-state relays is to
be checked on an individual basis.
