• The type of mains, current and voltage of the mains connection
must match the details on the rating plate of the pump as well
as the rating plate specifications and documentation of the
switchgear.
• Provide fuse protection on the mains side (max. 10 A, slow-
blow) as well as a residual-current-operated protection switch
in accordance with the applicable regulations.
• To increase the operational reliability, we recommend the use
of an automatic circuit breaker (which disconnects all power
leads) with K characteristic.
• Feed the ends of the pump cable through the cable screw fit-
tings and cable inlets and wire them according to the markings
on the terminal strip (Fig. 5 or Fig. 6).
• The electrical connection must be established via a fixed power
cable (3 x 1.5 mm
2
, minimal cross-section), equipped with a
plug and socket connector or an all-pole switch with a mini-
mum contact opening width of 3 mm.
• To ensure drip protection and strain relief on the threaded cable
connection, use cables with a sufficient outer diameter and
screw the threaded cable connection tightly. In addition, the
cables near the screwed connection are to be bent to form a
drainage loop, to drain any accumulated drips.
• Earth the switchgear according to regulations.
