Note before mounting:
Don’t place or install the device in area near water or
moist, keep the relative humidity of the device
surrounding between 5%~95% without condensation.
Before power on, first confirm the supported power
supply specification to avoid over-voltage damaging the
device.
The device surface temperature is high after running;
please don’t directly contact to avoid scalding.
【Installation of Wall-mounted Device】
Step 1 Place the device on the wall for reference or
reference the mounting dimension to mark the
position of 2 screws.
Step 2 Place the device on marked wall and tighten the
screw to marked position, mounting ends.
【Disassembling of Wall-mounted Device】
Step 1 Power off the device.
Step 2 Hold the device and screw out the bolt on the wall.
Step 3 Take out the device, disassembling ends.
【Power Supply Connection】
5VDC power supply input
The external power supply of model Ⅱand model Ⅲ
supports 5VDC power supply input. DC round-head,
inner ring is the positive pole, outer ring is the negative pole.
model Ⅲsupports 2.0A overcurrent protetion. Power supply:
5VDC.
12~48VDC power supply input
