2.3 Driver installation requirements
Please install the driver vertically or horizontally, with its front facing forward, top facing upward to
facilitate cooling.
During assembly, avoid drillings and other foreign matters falling inside the driver.
During assembly, please use M3 screw to fix.
When there is vibration source (such as a driller) close to the installation position, please use a vibrating
absorber or a vibration resistant rubber gasket.
When multiple drivers are installed in the control cabinet, please pay attention to reserve enough space
for sufficient heat dissipation. If necessary, you can configure cooling fans to ensure good heat
dissipation conditions in the control cabinet.

3.2 Power supply input
The driver's working power is DC power, and the input voltage range is between 24V ~ 50V.
Input power polarity should not be reversed!!!
The driver’s work mode is constant current control. The driver output the voltage to motor by changing
the input power into PWM chopping wave when it is working. In this case, the input power will affect the
performance of driver.
