• Check the current type and voltage of the mains connection.
• Observe the rating plate information for the pump. The current type
and voltage of the mains connection must correspond to the details
on the rating plate.
• Fuse on mains side: 10 A, slow-blow.
• Earth the pump/installation in accordance with the regulations.
NOTE
The connection diagram for the electrical connection can be found in
the terminal box cover (see also Fig. 4 - 6).
• For connection voltage see motor rating plate.
• When connecting automatic switchgears/frequency converters,
observe the corresponding installation and operating instructions.
The following are to be observed in addition to other aspects:
• Appropriate cable with sufficient cross-section (max. 5% voltage
loss).
• Connect correct shielding according to the recommendation of the
frequency converter manufacturer.
• Install data cables (e.g. PTC analysis) separately from the mains
cable.
• Possible utilisation of a sine filter (LC) upon consultation with the
frequency converter manufacturer.
Installation/setting of the motor
protection switch
• The use of a motor protection switch is necessary.
• Set according to the nominal motor current specified on the rating
plate of the motor, Y-
Δ
starting: If the motor protection switch is
switched in the supply line to a Y-
Δ
contactor combination, set the
switch as for direct starting. If the motor protection switch is switched
in a thread of the motor supply line (U1/V1/W1 or U2/V2/W2), set the
motor protection switch to 0.58 x rated motor current.
