4 Application
The LORENTZ PowerPack PP4000S allows PS2-4000
systems to be powered by an AC power supply
from the grid or a generator*. Typical uses are for
powering the system overnight or for meeting higher
water demands in low solar power situations. If PV is
disconnected, a separate timer switch can be used
to control the AC power supply to the PowerPack
in cases where scheduled use of the PowerPack is
necessary (e.g. to extend pumping time).
Figure 1: System layout
The PowerPack can be remotely activated through
its remote-control terminals by means of a separate
switch or a contact signal. Further details can be
found in section 4.2.
*Running the pump with a PowerPack can reduce the
maximum speed of the pump in some applications.

l WARNING – Before changing power
sources, the PowerPack and controller
must be switched o and the AC and DC
power sources must be disconnected.
WARNING – The following feature
should only be operated by qualied
personnel.

Description
Pos 1. 210 V Default position that secures operation for all PS2-4000 pump systems
Pos 2. 223 V Applicable for most C-SJ pumps and lifts
Pos 3. 233 V Applicable for most C-SJ pumps and lifts
Pos 4. 250 V Recommended only for HR pumps
The PowerPack comes pre-congured to a voltage of
210 V DC in position 1 which is safe to work with all
PS2-4000 systems under all conditions. However, in
many applications this voltage can be set to a higher
value as written in table 2.

6 Application Installation 7
Figure 2: Voltage switch selector
Increasing the voltage above the pre-congured level
may result in interactions between the controller and
the PowerPack that cause stops and restarts. In this
case, reduce the voltage setting.
This setting should only be modied by professional
personnel and is the user’s own responsibility.
LORENTZ recommends keeping the default value and
provides further technical suggestions in table 2.
COMPASS can be used to check the expected
performance of your system based on the selected
voltage setting.
4.2 Remote On/O function
This PowerPack includes a normally open (NO)
terminal for remote control. Closing the contact
between the remote on/o terminals will switch o
the DC output of the PowerPack.
Note: This feature does not oer a dedicated
automatic control function in combination with the
PS2-4000.
