Reset Button
• Reset. Press and hold the reset button for 5 seconds until the LED
indicator flashes Red 3 times quikly to clear the Wi-Fi information
(energy data will not be cleared). After that, the LED indicator will blink
Green and wait for pairing.
Note: If you want to clear the energy data, please delete the device and
wipe data on the app then add it again.
LED indicator
The LED status gives the following information of the power clamp:

Impoant safety information!
• The power clamp must be installed and seiced only by a qualied
electrical personnel.
• Do not touch the terminals of the device during testing.
• Turn o all the power supply for this equipment before installing.
• Make sure that the power supply is off before connecting or
disconnecting it to an auxilia device.
• Always use a properly rated voltage sensing device to confirm
power is o.
• Replace all devices, doors and covers before applying power to the
equipment.
Failure to follow these instructions will result in death or serious
inju.

Please make sure the main power in your facility is off before
installing
Get staed:
1. Open the clamp to see the arrow (P1→P2) or (K→L) or you can nd
it on the sticker on the outside of the clamp. This is the direction of
CT. The CT suppo bi-directional sensing. If the direction of the CT is
opposite to the direction of the current, the power will be negative.
2. Apply the CT on the electric cable and ensure the direction of CT is
correct when installing in dierent scenarios:
•To measure energy consumption
The arrow on the clamp should face to the correct direction of the
electricity current ows like CT1 in the wiring diagram. In this case,
the power will be positive, and the energy consumption will be
accumulated.

•To measure energy generation
The arrow on the clamp should face to inveer like CT2 in the wiring
diagram. In this case, the direction of the current is opposite to that of
the CT. The power will be negative, and the energy generation will be
accumulated.

For CT1:
If the measured current direction is K → L, the energy consumption is
accumulated as ‘From Grid’ energy.
If the measured current direction is L → K, the energy generation is
accumulated as ‘To Grid’ energy.
•To measure 'From Grid' or 'To Grid'
To monitor how much energy is pulling from and sending back from the
grid, install the CT on the leads coming from your mains like the CT1
below.
