【Precautions】
Please use DC 12~48V standard industrial power supply, typical voltage are
12V/24V/48V.
Cover the unused fiber optic ports with caps to prevent it from contaminating.
Do not stare the fiber optic output ports directly, the laser should injure you eye.
Connect the device to ground properly, there is specified GND screw on the side-board,
connect it with specified Ground Wire.

【Grounding and Power Supply】
Ground Connection: There is a ground (GND) screw on side-panel of the device,
connect the screw to ground terminal of the work place with ground wire. The ground
wire is required at least 2.5mm2and less than 5Ω resistance.
Power Input: The power input support voltage range DC 12~48V, you should use the
copper power wire above 0.75mm2.
【DIN Rail Mounting】
Follow these steps to install the device to DIN-Rail:
Step 1:Check the DIN-Rail Clip is fixed on the back panel of the device;
Step 2:Check DIN-Rail is stable and there is enough room to install the device;
Step 3:Insert the button edge of DIN rail into the clip slot just upside the stiff metal spring;
push the device forward slightly and the DIN-Rail Clip will snap into place as
shown in the following illustration.
Step 4:Check to make sure the device is installed to DIN Rail firmly.
