Open circuit (no-load) voltage
above 50 V will destroy
the controller. This may occur if the wrong PV modules
(solar panels) are used, or if the solar array is incor-
rectly wired. Measure the array voltage before connect-
ing to the controller. A “12 V” (nominal) array should
produce an open circuit voltage around 22-25 V under
any daylight conditions.
Do not attempt
to use this
controller for any motors
other than
ECDRIVE

.
To be installed, connected and serviced
by qualified
personnel only
. Ensure all power sources are discon-
nected when making connections to this unit. Follow all
appropriate electrical codes. There are no user service-
able parts inside the motor or the controller.
5.2 Warnings to Installer
Location
Place the controller close to the solar array,
not the pump. This will reduce the risk of lightning
damage.
Protection from heat
Electronic devices are most
reliable when they are protected from heat. Mount the
controller in the shade of the mid-day sun. An ideal
location is directly under the solar array or in a nearby
shaded location. An alternative is to fold a piece of
sheet metal so that it mounts behind the controller and
curves over it to provide shade. This provides protection
in extremely hot climates.
5. 3 Mechanical Installation
Install
proper grounding for safety and lightning
protection
Do not touch the controller input or motor wires
together to test for a spark.
TEST THE VOLTAGE
before connecting power to the
controller. Voltage (open circuit) must not exceed 50 V.
Some thin-film PV-modules may produce excessive
voltage, especially when they are new. If the open circuit
voltage exceeds 50 V,
DO NOT
connect power to the
controller. Contact your supplier.
Battery system
Place the controller near the batteries
but safely isolated from the battery terminals and from
corrosive gases. (Batteries must be in a cool location
for best longevity and enclosed for cleanliness and
safety.) Connect the battery (12 or 24 V) directly with the
+ and – Terminal of the controller. Do not use the load
terminals of the charge controller as they maybe not
strong enough to allow the start current to flow. The
PS150 controller has a low voltage function to protect
the batteries from deep discharge. The charger (addi-
tional) is only needed for charging the batteries.
Position
If it is outdoors, mount the controller in a
vertical position to assure that rain will not enter the
box.
