PP4000 AC PowerPack
AC/DC converter to power PS4000 pump systems
from a generator or utility power
InStAllAtIon
WArnIng this device is to be installed,
connected and serviced by qualified
personnel only. Ensure all power sourc-
es are disconnected when making con-
nections to this unit. Follow all appropriate electri-
cal codes. there are no user-serviceable parts inside.
Mounting
Mount the AC PowerPack close to the pump controller, in
a vertical position. Cover the unit from direct rainfall. You
will find four mounting brackets in a plastic bag inside the
enclosure.
WArnIng PowerPack must be protect-
ed from solar heat, especially direct
mid-day sun. Mount it in the shade. If
there is no shady location, make a
shade from sheet metal. Allow free air
circulation around the cooling fins on
the back of the enclosure.
WArnIng Power Pack must be oFF
while it is being wired to the solar
pump controller, or controller damage
may result. never connect it while it is
“hot”.
Connections
For all connections, see the description on the sticker on the
back of the device.
Wire Sizes
All wires must be #14 AWG (2.5 mm
2
) or larger.
grounding
Connect propper ground to the yellow-green wire of the
AC cable.
AC Input
Connect propper ground to the yellow-green wire of the AC
cable. Connect AC power to the phases L1, L2, L3. As there
is always a ballanced load on the three phases, a neutral
connection is obsolete. Be aware, that in most installation
codes it is not allowed to use a 5-pole plug (3P + 1N + 1
PE) for this, because the neutral is not connected. Use a
4-pole plug instead, according to the local standards.
DC PoWEr oUt
Connect the two wires from the DC POWER OUT plug to
the POWER IN + and – terminals in the solar pump control-
ler. Install a properly rated DC disconnect switch between
the PP4000 and the solar pump controller if it is operated
together with a solar generator. Install a properly rated DC
disconnect switch between the solar generator and the
pump controller, too.
WArnIng – only one of the power
sources must connected at a time.

the Problem
Some solar pumps may not provide sufficient flow under all
conditions, especially in unusually cloudy weather or when
sufficient storage cannot be provided.
the Solution
LORENTZ AC PowerPack allows the pump to be powered by
an AC generator or commercial utility power. The PowerPack
will power the pump to its full capacity. With some systems,
it will produce a greater flow rate than you will see with
solar power.
