By means of the speed switch, the pump performance
can be adjusted to suit the system in question.
For 1 x 115/230 V and 3 x 208/230 V three-speed
pumps only. The module is located inside the terminal
box. It has three positions:

Note: UP pumps runs at 100%.
Change to a lower speed enables considerable
reduction in energy consumption and less noise in the
system.

Two-speed pumps
All UPS pumps with 3 x 460 V & 575 V terminal boxes
are fitted with a special two-speed terminal block.
Fig. 11 3 x 460 V & 575 V terminal box
The speed is changed by changing the jumper
positions.
The pump must be connected to the mains via an
external contactor. The contactor is to be
connected to the pump’s built-in thermal overload
switch (terminals P1 and P2) to protect the pump
against overheating at both speeds.
Speed selection (two-speed, 3 x 460 V and 575 V)
The speed setting in the terminal box can be changed
to two positions. The speed in the two positions
appears in the table below
