Circuit Monitoring Installation

1 - Electrical Connections

Electrical Preparation

This installation must be performed by a qualified electrician or authorized technician only due to high voltage hazards

  • DIN rail mounting is recommended for both the power supply and relays

  • 2-core 0.75 mm² wiring can be used for the AC supply, DC output and relay connections

  1. Locate the 230 VAC supply or electrical distribution board

  2. Isolate the electrical supply and verify that it is de-energized

  3. Install the 230VAC/12VDC power supply (PSR-01512) to power the IOTPRO

  4. Identify the circuit to be monitored, typically at the circuit breaker output

  5. Install the relay socket (GZM80) and relay (RM85-2011-25-5230). Connect the relay coil terminals as follows:

    • A1: Circuit breaker output (L)

    • A2: Corresponding Neutral (N) from the distribution board

  6. Repeat steps 4–5 for each additional circuit to be monitored, up to a maximum of 6 circuits

IOTPRO Wiring

Refer to IoT Pro Opening and Closing for instructions on opening the device to access its wiring connections.

Refer to the wiring diagram below and complete the following steps:

  1. Route the 12VDC power supply connections through the first cable gland. Connect the positive (+12V) and negative (GND) wires to the corresponding IOTPRO power terminals.

  2. Connect each relay's dry contacts to the corresponding IOTPRO digital input:

    • Terminal 11 (COM): Connect to DIN1–DIN6, respectively

    • Terminal 14 (NO): Connect to IOTPRO GND

  3. Verify all electrical connections, secure and conceal the wiring, tighten the cable glands and securely close the IOTPRO enclosure. Once the installation has been checked, the electrical supply can be safely re-energized.

Use an 8-core, 0.25 mm² cable, such as LAPP UNITRONIC LiYY (MPN: 0028308), to simplify wiring between the IOTPRO and the six relays. Allocate six conductors to DIN1–DIN6 and the remaining two to the shared GND connections, distributing them between the relays as required.

2 - Mechanical Installation

Refer to IoT Pro Installation Options for different installation options. Wall anchors are recommended for most applications.

3 - System Commissioning
