Reset Button
• Reset. Press and hold the reset button for 5 seconds until the LED
indicator ashes Red 3 times quikly to clear network information (energy
data will not be cleared). After that, the LED indicator will blink Red and
wait for joining ZigBee network.
• Clear Energy Data. Reset the Power Clamps twice consecutively
The inteal between two reset must be less than 10S. After successful
operation, the indicator light will flashe alternately red and green 3
times.
LED indicator
The LED status gives the following information of the power clamp:
LED Status What it means
Green LED solid on Device has joined a ZigBee network.
Red LED blinking Device has not joined a ZigBee network.

Please make sure the main main breaker is o before installing!
Get staed:
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. Connect AC Input cable to a socket near the Electrical Box to power
on the Power Clamp according to the wiring diagram. And apply the
CT on the electric cable and ensure the direction of CT is correct when
installing in dierent scenarios:

Note: When installing, please ensure that the circuit measured by CT is
in the same phase as the circuit powered by PC311.
•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 inveer 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. Note: When installing, please ensure that the circuit measured
by CT is in the same phase as the circuit powered by PC311.

2Mounting
The Power Clamp has a mounting bracket for mounting purposes. You
can choose the following two mounting methods:
• Use the mounting bracket as template to mark the two holes on the
wall for installing screws. Screw the mounting bracket onto the wall
according to marked location. Install wall plugs if necessa.
• Sliding the mounting bracket through one end of the Din-Rail if you
want to x on the Din-Rail.
After the bracket is installed, snap the Power Clamp onto the bracket.
