1 2 Purchase Inspection
CAUTION: Properly check the delivery
before installation Never install the
controller when you find it damaged or
lack a component Incomplete or
defective installation might cause
accidents
CAUTION: The submersible motor is a
waterfilled AC machine Always
observe the instructions delivered
together with the motor according to
its waterfilling These instructions can
be found in the motor manual or on
the motor body itself Ignoring these
instructions will shorten the product
lifetime and damage the motor
permanently
1 3 Installation
CAUTION: To ensure effective cooling,
the controller must be installed
vertically with at least 10 cm space
above and below the casing
CAUTION: When installed in an indoor
location sufficient ventilation must be
ensured by a vent or ventilator or
similar device Do not install in a place
which is exposed to direct sunlight
CAUTION: Do not let the drilling chips
fall into the controller fin or fan during
installation This might affect the heat
dissipation
CAUTION: To avoid multiple starts of
the pump in twilight conditions, a
SunSwitch must be installed and
configured according to COMPASS
data Multiple starts due to an
incorrectly configured SunSwitch can
lead to increased wear and damage
the pump Such damage is excluded
from the warranty
1 4 Connection
WARNING: The connection of the
controller must be carried out by
qualified personnel only Unqualified
handling might lead to shock, burn, or
death
WARNING: Please double-check that
input power has been disconnected
before connecting the device,
otherwise electrocution or fire can be
caused
WARNING: The earth terminal must be
reliably grounded, otherwise touching
the controller shell might lead to a
shock
WARNING: Selection of PV module
type, motor load and controller must
be adequate, or the equipment might
get damaged
WARNING: Grounding of this electrical
equipment is mandatory Never run the
pump system when the ground wire is
not connected to proper ground
Ignoring this instruction can lead to
electrocution
1 5 Operation
WARNING: The controller should only
be connected to power after correct
wiring, or the controller might get
damaged
WARNING: Do not modify the
connection while the system is
connected to power, or touching any
part of it might cause electrocution
CAUTION: Adjust partial control
parameters according to the steps
indicated by the manual before the
first operation Do not change the
control parameters of the controller by
random, or it might damage the
equipment
CAUTION: The heat sink gets hot during
operation Do not touch it until it has
cooled down again, or you might get
burned
CAUTION: At altitudes of more than
1,000 m above sea level, the controller
should be derated for use Output
current should be derated by 10% for
every 1,500 m increment of altitude
CAUTION: Never run the pump when it
is not fully submerged in water When
the pump is installed the correct
rotiational direction can be determined
by measuring the flow rates
1 6 Others
Maintenance and inspection must be performed by
qualified personnel only
Do not dismantle the controller while connected
to power For conduct maintenance and inspection
wait at least 5 minutes after the power has been
switched off
No serviceable parts inside the controller Opening
the controller will void the warranty
Treat the controller as industrial waste when
processing the discarded controller It is possible
that the electrolytic capacitor will explode during
incineration and that parts of components will
produce toxic and harmful gas
