• Have the electrical connections established by approved electri-
• Adhere to regulations for accident prevention!
Operation of the IPL on Wilo control devices:
In conjunction with a control device (e.g. Wilo-CC system or Wilo-SC
system), the power of the pumps can be continuously controlled. This
allows optimisation of the pump output for the demands of the
installation and economically efficient pump operation.
Operation of the IPL on external frequency converters (third-party
products):
In principle, the motors used by Wilo are suitable for use with external
frequency converters or third-party products if they comply with
the conditions specified in the application guidelines DIN IEC/
TS 60034-17 and/or IEC/TS 60034-25.
The pulse voltage of the frequency converter (without filter) must be
below the limit curve shown in fig. 7. This is the voltage that is applied
to the motor terminals. This is not only determined by the frequency
converter, but also, for example, by the motor cable used (type,
cross-section, shielding, length, etc.).
DPL:
Two pumps are arranged in a shared housing (double pump). The
pump housing has an IN-LINE design (fig. 8). All pump housings are
provided with pump bases. Mounting on a foundation base is recom-
mended for nominal motor powers of 4 kW and higher. The base-load
pump is only operated in control operation in conjunction with a con-
trol device. The second pump is available as a peak-load unit for full
load operation. Moreover, the second pump can adopt the reserve
function in the event of a fault.
NOTE
Blind flanges, which allow the motor impeller unit to be replaced even
in double pump housing, are available for all pump types/frame sizes
in the DPL series (see chapter 5.4 "Accessories") (fig. 8 right). A motor
can therefore remain in operation while replacing the motor impeller
unit.
