KSB UPA - Installing Pump Set in Angled Position; Notes on Electrical Connection

5.5 Installing the pump set in an angled position
NOTE
Observe all safety instructions contained in this manual for the following
installation instructions.(⇨ Section 5.1 Page 20
)
The pump sets are suitable for angled installation, provided they have been selected
for this type of installation. See order documentation or data sheet.
Angled installation of a submersible borehole pump always requires structural
adjustments. For angled installation, always refer to the additional documentation
supplied with the delivery.

)
A2 Permissible up to
maximum 3°
Installation see section: Installing the pump set in
a horizontal position
B Permissible installation position, if approved in the order documentation
C Impermissible The pump set must not be installed in this
position.
5.6 Notes on electrical connection
KSB's submersible borehole pumps > 1000 V are wired for DOL starting. During start-
up and run-up the voltage must not fall below the value specified in the order
documentation.
If this starting method is not permitted by the power supply utility, starting devices
to reduce starting currents must be provided (e.g. autotransformers, starting resistors
or soft starters ).
General information on the motor
Motor protection
Provide a temperature-compensated overcurrent relay of tripping class 10 or 10 A as
motor protection. If an earth leakage relay is used, it must be fitted in the motor
power circuit.
