Precautions
WARNING:
• When installing in a potentially explosive environment, make sure that the motor is
properly certified.
• You must ground (earth) all electrical equipment. This applies to the pump equipment,
the driver, and any monitoring equipment. Test the ground (earth) lead to verify that it
is connected correctly.
• Motors without built-in protection must be provided with contactors and thermal
overload protection for single-phase motors, or starters with heaters for three-phase
motors. (See the nameplate on the drive unit to select properly-sized overloads.)
NOTICE:
Supervision by an authorized Xylem representative is recommended to ensure proper
installation. Failure to do so may result in equipment damage or decreased performance.
Evaluate the installation in order to determine that the Net Positive Suction Head Available

4.1.1 Pump mounting guidelines
Series e-580 pumps can be mounted with the motor shaft horizontal or vertical (motor
shaft down). When the optional Integrated Technologic with Sensorless Control (ITSC) or
Integrated Technologic (IT) is installed, the pump can only be installed with the motor
shaft vertical (motor shaft down).
The optional ITSC or IT can be oriented to different positions relative to the pump nozzles.
This can be easily changed during pump installation by removing the motor mounting
capscrews, raising the motor assembly slightly, 0.015 to 0.030" (if needed), and rotating
the motor assembly around the pump centerline. Raising the motor assembly more than
0.030" could damage the mechanical seal. Replace the motor capscrews when the
preferred position is determined.
CAUTION:
The pump and motor assembly must be properly supported during this procedure to
prevent the pump unit or motor assembly from falling. Failure to properly support the
pump and motor assembly could result in personal injury and or property damage.
4.1.2 Pump location guidelines
WARNING:
Assembled units and their components are heavy. Failure to properly lift and support this
equipment can result in serious physical injury and/or equipment damage. Lift equipment
only at the specifically identified lifting points. Lifting devices such as eyebolts, slings, and
spreaders must be rated, selected, and used for the entire load being lifted.
