CONNECTION DESCRIPTION
Please check whether the laser module is compatible with your engraving machine before connection.
A. Check the voltage parameter of you engraving machine.
Please ensure your engraving machine can provide at least 24V 4A power supply.
B. Check the port of the main control board on your engraving machine.
Please find the PWM port, GND port and VCC port on the main board of your engraving machine. Then connect this laser module to the main board accordingly.
“A”&”B” are both Compatible.
Connect the laser module to the main board of your engraving machine directly.
Only voltage is not matched.
The voltage parameter of your machine are not matched to the module.

| 24V4A | 24V4A | Plug and Play |
Step 1
Connect the cable of your engraving machine to the corresponding input connector on P-DA-01.
Step2
Connect the cable of the laser module to the Output A connector on P-DA-01.
Step3
Connect the 24V power adapter to the DC Input connector on P-DA-01. Push the switch to EXT position and the power is provided by external power adapter.
Only control board pin definition is not matched.
Situation 1: The definition of connector on the engraving machine main board is not pin-to-pin.
Please rearrange the wire sequence of the cable to make each wire is well matched with the pin definition on the engraving machine main board.
Situation 2: Please use P-DA-01 if the main board of your engraving machine is not 3pin, such as 2pin.

PRECAUTIONS
Laser may cause damage to your skin. Please do not expose your skin directly to the laser. Please wear laser goggles to protect your eyes when you use this laser module. Please ensure that the air pump is turned on before you start cutting. If not, the smoke will contaminate the lens. This laser module doesn’t support hot plug, hot plug may cause damage to the laser module.
MAINTENANCE
When the laser module is not used for a long time, please ensure that the lens is not polluted by dust. When you replace the air nozzle, please ensure that your operation will not pollut the lens. Finger prints or dust on the lens will weaken the output power of the laser module, or even damage the lens. When you find the cutting ability decreases, the lens might be not clean.
Please use a clean alcohol swab to clean it according to the following figure.
