The voltage is changed by changing the orientation of
the jumpers. See fig. 12.
The pump must be connected to the power supply via
an external switch.
The UP pumps are equipped with a built-in, automati-
cally resetting terminal overload switch, protecting the
pump at both 115 V and 230 V. The built-in terminal
overload switch (terminals P1 and P2) can optionally
be connected to external overload protection.
Pumps with standard module
Fig. 13 Terminal box with standard module
The standard module is standard in three-phase
pumps with three speeds and forms connection
between supply terminals and motor.
The pumps with standard module must be connected
to the power supply via an external contactor.
For motor protection the contactor is to be connected
to the pump’s built-in thermal overload switch to
protect the pump against overheating at all three
speeds.
Standard module indicator lights
The indicator lights on pumps with standard module
show whether the pump is live, or whether the phase
sequence of three-phase pumps is wrong.
Single-phase pumps
Single-phase pumps incorporate a green indicator light
only:
Three-phase pumps
Three-phase pumps have a green and a red indicator
light:
Variable frequency drive operation
All 3 x 460 V, 3 x 575 V and 3-speed 3 x 208-230 V
pumps with standard module are suitable for variable
frequency drive (VFD) applications. Please note the
following:
• Even if the red indicator light is on, the pump is
operating normally.
• Pumps fitted with other modules than the standard
module must not be connected to a VFD.
• Depending on the VFD type, this may cause
increased acoustic noise from the motor.
Furthermore, it may cause the motor to be exposed
to detrimental voltage peaks.
• The motor must be protected against voltage peaks
higher than 650 V between the motor terminals.
Acoustic noise and detrimental voltage peaks can be
reduced by fitting an LC filter between the VFD and the
motor.
Pumps with protection module
The protection module is standard for single-phase
UPS pumps and available for 3 x 208-230 V UPS
pump models only as an option.
When fitted with a protection module, the pump can be
connected directly to the power supply switch as it will
be protected by the built-in overload protection.
The protection module incorporates two indicator
lights.
