Safety Precautions
1
．
Please make sure that all wires and connecting parts are well insulated before connecting the ESC to
related parts. Short-circuiting will damage the ESC.
2
．
Please read the manuals of all the power equipment and the frame carefully before using the ESC to
ensure that the power is reasonably matched, and avoid the motor overload due to the wrong power
combination, which will eventually damage the ESC.
3
．
Please carry out wiring and debugging when the car is suspended for your safety and others'.
4
．
Please disconnect the battery and ESC after use. If the battery is not disconnected, even if the ESC
switch is turned off, the ESC will continue to consume power. If the battery is connected for a long time without
use, the battery will eventually be completely discharged, which will cause the malfunction of the battery or
ESC.
RadioLink is not responsible for any damage caused by incorrect operation!
Part 1. Introduction of COOL 9030
1.1 COOL 9030 Overview
Power input: The power input of the ESC is connected to the power supply. At the same time, the
voltage range of connected power supply should be within the range of 6~16.8V (for non-lithium batteries: NI-
MH battery, nickel-cadmium batteries and lead-acid batteries, etc.), and 6-18V (for lithium batteries). Power
supply outside this voltage range cannot guarantee the stability of the system.
Motor output: The motor connector is used to connect a brushed DC motor. At the same time, the rated
working voltage of the connected brushed DC motor must meet the power supply voltage range of the ESC.
Otherwise, the stable operation of the ESC and the connected motor cannot be guaranteed.
