Mounting
Notice Before Mounting
- Avoid placing or installing the device in areas near water or moisture. Maintain relative humidity between 5%~95% without condensation.
- Before powering on, confirm the supported power supply specification to prevent over-voltage damage.
- The device surface may become hot after running; avoid direct contact to prevent scalding.
Wall-mounted Device Mounting
Step 1: Attach the left/right mounting boards to the device's backboard using M3 screws.
Step 2: Position the device on the wall for reference or use the mounting dimensions to mark two screw positions.
Step 3: Install M4 screws into the wall, leaving a 2mm interspace.
Step 4: Hang the device onto the two screws, slide it downward, and tighten the screws for stability.
Wall-mounted Device Disassembling
Step 1: Power off the device.
Step 2: Unscrew the wall mounting screws by approximately 2mm.
Step 3: Lift the device slightly upward, remove it, and disassembling is complete.
Power Supply
Notice Before Power On
Power ON: Insert the power supply terminal block into the device's power supply interface, then plug in the power supply and turn it on.
Power OFF: Unplug the power supply first, then remove the power line. Follow this order.
Power Supply Connection
The device supports one DC power input via a 3-Pin 5.08mm pitch terminal block. V+ and V- are for DC input, and FG is for power grounding. The power supply is non-polar and supports a range of 12-48VDC.
