Get to know your device

Current Transformer Cable

Reset Button

Press and hold the reset button for 5 seconds until the LED indicator flashes 3 times quikly to restore the power clamp to default factory settings energy data will not be cleared.

LED indicator

The LED status gives the following information of the power clamp

Installaion

Important safety information

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

Get started

Please make sure the main power in your facility is off before installing. Follow the schematics below as an example to wire the Power Clamp for different phase.

3 Phase electricity wiring

Single Phase electricity wiring

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.

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 flows (P1→P2). If the arrow faces the reverse direction, the reading meter will display 0.

Tips about the clamp

Cable diameter does not affect usage as long as the cable can pass through the clamp hole. The meter has three clamps which can be applied to cable devices for separate measurement. If applied to the same cable, all clamps will produce the same reading.

Configure Network

To get started, you will need

A ZigBee Gateway.

Adding to the gateway’s network

1. Set your gateway to permit joining.
2. Power on the power clamp and make sure the LED indicator is flashing green. If not, please reset it.
3. After few seconds the power clamp will join the gateway automatically. After adding successfully, you can see the new power clamp in the application.

Mounting

The Power Clamp has a mounting bracket for mounting purposes.

1. Use the mounting bracket as template to mark the two holes on the wall for installing screws.
2. Screw the mounting bracket onto the wall according to marked location.
3. Install wall plugs if necessary.
4. Locate the hooks of the mounting bracket and line up the hooks with the mounting holes on the Power Clamp.
5. Fit the hooks into the mounting holes as the picture below. Installation is now completed.
