6. Sleeping Mode

R718N3 is designed to enter sleeping mode for power-saving in some situations:
(A) While the device is in the network → the sleeping period is Min Interval. (During this
period, if the reportchange of three-phase current is larger than setting value, it will wake up
and send a data report).
(B) When it is not in the network → R718N3 will enter sleeping mode and wake up every 15
seconds to search a network to join in the first two minutes. After two minutes, it will wake up
every 15 minutes to request to join the network.
If it's at (B) status, to prevent this unwanted power consumption, we recommend that users
remove the batteries to power off the device.

7. Low Voltage Alarming

The operating voltage threshold is 3.2V. If the battery voltage is lower than 3.2V, R718N3 will
send a low-power warning to the LoRa network.

8. Measurement Range and Accuracy

R718N37 (open loop CT) measurement range is 1A~75A (±1%),
R718N315 (open loop CT) measurement range is 1A~150A (±1%),
R718N325 (open loop CT) measurement range is 1A~250A (±1%),
R718N363 (open loop CT) measurement range is 10A ~ 630A (± 1%).

9. Installation

This product comes with waterproof function. When using it, the back of it can be adsorbed on the
iron surface, or the two ends can be fixed to the wall with screws. When installing the current
transformer, separate the fire and neutral wires of the three-phase electric power, and take out the fire
wire through current transformer and start the measurement according to the wiring below:
(Current direction, K-->L)
