Pro-Tronik A2Pro UBEC 4 A-5,6V Mode D'emploi page 9

We strongly recommend that you use the second solution.
Also for reasons of reliability, we recommend that you do not put a switch on the path of the power of the reception.
ONBOARD INSTALLATION

To avoid disruption of the radio link, it is essential to put your U‐BEC as far as possible from radio parts, especially the receiver and its
antenna.
Also for security reasons, it is essential to provide open space around your U‐BEC. This space should allow the circulation of fresh air entering
the fuselage in order to remove the dissipated heat. Verify that the air outlet is free of the fuselage section and sufficient.
2 / TESTS
If your controller has a BEC circuit, you must disable it before connecting your U‐BEC to the receiver (UBEC 5,6V). To do this, simply remove
the center pin of the servo connector, and insulate it by a section of shrink sleeve. If this precaution is not taken, you may destroy the controller
and / or U‐BEC.
It is imperative to carefully check that the consumption of the reception of your model (receiver + servos operating) does not exceed the
maximum current allowed by your U‐BEC before flying. Always perform tests on the ground, turning the motor on the total discharge of the
battery, and regularly moving the rudder as on a "classic" flight (to simulate a normal consumption of the servos).
It is normal after this test that your U‐BEC gets slightly warm. However, if the temperature is such that you can not keep it in your hand, do not fly!
Check the power consumption of each item on your receipt to determine the cause of overconsumption.
Unable to monitor compliance with the installation of the module in a template, A2Pro will not accept any liability resulting from a crash which
resulted in damage to persons and property, including model.
We also draw your attention to the danger posed by an electric motor in operation, both for goods and for people. We recommend that you
perform the tests on a work plan completely empty of any object in the absence of other people or animals. Please also note that the electric
motor can become very hot during use, causing a risk of burns. The best precaution is to systematically remove the propeller during the tests.
3 / IMPORTANT NOTES
Never leave the battery connected to U‐BEC module and controller over a long period. Under these conditions, the U‐BEC module and
controller continue to consume current that, over time, can fully discharge the battery. Therefore, we recommend that you use to just connect the
battery before using your model, and then disconnect the battery immediately after use.
If your controller has a built‐in BEC, it is necessary to disable it before connecting your U‐BEC receiver. To do this, simply remove the center
pin of the servo controller, and insulated by a section of shrink sleeve. If this precaution is not taken, you may destroy the controller and / or U‐
BEC.
The U‐BEC circuit has a current capacity which does not depend on the battery voltage. However, it is essential to verify that the total current
consumed by the servos / accessories under load does not exceed the current capacity indicated in the characteristics of the device.
When the module delivers maximum current indicated, the nominal output voltage is satisfied only if the battery voltage is greater than the
value indicated in the characteristics of the device. Below this voltage, the module will deliver a slightly lower voltage. From 3 LiPo, the nominal
output voltage will be ok whatever the current consumed (UBEC 5,6V).
 Do not reverse polarity of power supply (destruction not covered by the warranty).
 Always use good quality gold connectors.
 Make a systematic range test at a safe distance before each flight, with and without motors.
 It is normal that the module U‐BEC gets slightly warm after prolonged use. Also, it is essential to provide its breakdown, just like the controller.
Any breach of this rule will result in loss of warranty.
