3. Open the clamp as shown below. Apply it on the electric meter
cable. The arrow on the clamp should face to the correct direction of
the electricity current 󽗊ows (P1 → P2). If the arrow faces the reverse
direction, the reading meter will display 0.
Follow the steps below:
1. Connect AC Input cable to a socket near the Electrical Box to power
on the Power Clamp according to the corresponding phase wiring
diagram.
2. Attach both ends of the Current Transformer Cables first like the
picture shown below. Then spinning the waterproof latch clockwise
until both ends have been tightened and secured.

for separate measurement. If applied to the same cable, all clamps
will produce the same reading.
4Con󽗉gure Network
4.1 To get started, you will need:
• Connect your phone to the 2.4Ghz Wi-Fi network.
• A mobile phone with a 'SmartLife' APP installed.

2. How to identify the Power Clamp is powered on?
1. You can press the reset button once, if the LED indicator 󽗊ashes red
3 times, which means the device is powered on.
3. Wi-Fi con󽗉guration of the device failed
- Con󽗉rm the entered router password is correct.
- Ensure that the DHCP service is enabled for the router. If not, the IP
address will be occupied.
- Please con󽗉rm the Wi-Fi network is stable:
Put the phone besides your device and make sure they are in the same
network environment, try to open a website to judge if the network can
be used.
- If your router supports both 2.4Ghz and 5Ghz, please enable the
2.4Ghz channel and add device under 2.4G Wi-Fi channel. You can
follow the following step on the App to con󽗉gure the router.
- Con󽗉rm that both the location permission of phone system and the
App are enabled.

15
- If it still does not work, it is recommended to change the router and
try again.
- If you have already upgrate the iOS system to 14, you need to enable
the 'Local network' of the App.
4. Device o󽗌ine
- Con󽗉rm whether the Power Clamp is powered on.
- Please confirm whether the home Wi-Fi network is normal, or
whether the Wi-Fi name and password has been modi󽗉ed.
- If there still have problems after the above checking, it is
recommended to remove the device or change the router to add it
again.
