SPM01 Monitor with Wireless Communication for 1P+N System

Product Information

The SPM01 Smart Energy Sensor/Monitor is an electrical
monitoring device with wireless communication. It is designed to
work as an accessory for protective and control devices in 1P+N
systems, such as circuit breakers and modular contactors. It
provides accurate energy metering, timely alarm reporting, and
smart automation settings.

The SPM01 is suitable for energy monitoring in buildings,
infrastructures, and industries. It can be installed at the main
circuit (incoming line) for whole-home energy monitoring.
Additionally, it can measure bi-directional current flow in
real-time, which can be used for dynamic load balancing with EV
chargers and PV power generation optimization.

The device has a metering certificate for billing purposes,
which can be extended based on the regulations of the
country/region.

Product Usage Instructions

1. Terminal Connection:
   • Insert the terminal plate into the protective device terminal
     box to receive power supply from Line (L).
   • Connect the cable to the power supply from Line (L).
   • Connect the cable to the power supply from Neutral (N).
2. Through-hole Placement:
   • Let the measuring cable (L) pass through the through-hole.
   • Ensure that the positive current flow aligns with the arrow
     direction.
3. Reset Button:
   • Press the reset button for 3-5 seconds to enter the pairing
     mode.
   • This is the same function as “Remove Device” in the APP.
4. LED Status Indication:
   • ON: Normal usage, connected to the cloud.
   • Flashing with 2Hz: Pairing mode.
   • Flashing with 0.5Hz: Paired, searching for cloud.
   • Flashing with 0.25Hz: Self-checking failed. Device needs to be
     replaced.
   • Flashing with 1Hz: Wireless communication failed. Input voltage
     is too low.
5. Current Flow Direction:
   • Ensure positive current flow direction for installation.
6. Order Number:
   • Refer to page 4 and 5 of the user manual for more details.

Note: Hanging-on-cable variants are recommended
if users are unsure about mount-on-MCB variant compatibility. Do
not pass both line cable and neutral cable through the same
hole.

Remark:

1) The Wifi and Zigbee modules from Tuya Smart use its proprietary protocol, which limits the devices’ direct

cloud integration to the Tuya Smart cloud. Tuya Integration at Home Assistant OS and API to Tuya Smart cloud

can be used to access the device indirectly. For customer-specific cloud integration or local smart home OS

integration, please use the products with Zigbee 3.0 standard meter cluster/attributes or contact us for other

solutions.

2) If users are not sure if the `mounted-on-MCB’ variants fit for the protection/control devices, `Hanging-on-cable’ variants are recommended.

Please note before starting Installation SPM01 must only be installed and maintained by qualified professionals. Qualified professionals refer to
those who have the skills, license and knowledge related to the manufacture, operation and installation of electrical equipment. They are trained to detect and avoid risks. SPM01 should not be installed if, while unpacking, any damage is observed. SPM01 must be installed inside electrical panels or switchboards, behind a door or plate, so that they are inaccessible for unauthorized persons. The electric panels must meet the requirements of the applicable standards (IEC 61439-1) and installed in compliance with current installation and safety rules (IEC 61140). All relevant local, regional, and national regulations must be respected while installing and using SPM01. SPM01 manufacturer declines any responsibility in the event that SPM01 equipment is associated with equipment that is not listed in the latest document of selection guide for product compatibility. SPM01 manufacturer is not liable in case the instructions mentioned in this document and other referred documents are not respected.

HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH Turn off all power supply sources before installing and during maintenance of this equipment. Do not use a SPM01 product for voltage testing purposes. A Voltage Tester must be used instead. Failure to follow these instructions can result in death, serious injury, or equipment damage.

FIRE HAZARD SPM01 must be associated with an easily accessible upstream protection and circuit-breaker system. The end of cable for L and N at SPM01 must be adjusted to the according equipment and device. Such an
adjustment can only be handled by qualified professionals. Failure to follow these instructions can result in death, serious injury, or equipment damage.

RISK OF DAMAGING SPM01 Sensor Comply with the phase and the neutral position. (Red=Phase, Blue=Neutral) Disconnect SPM01 before performing the dielectric withstand test. SPM01 can only be installed upstream if associated with contactors, frequency converter or motor starters. Limit the insulation measurements up to 500 V DC. Failure to follow these instructions can result in equipment damage.
