3.4.2 External Wattmeter

The external wattmeter used is the EM24-DIN.AV9.3X.IS.P. This must be installed in the main
panel of the dwelling in order to measure both the total consumption of the installation and the
photovoltaic generation and batteries of the ISS 1Play.
The energy consumption measured by the wattmeter is sent to the EMS Board via the RS-485
communication.
Proceed as follows:
1. Wattmeter electrical connection:
2. Connection of RS-485 wiring for communication with the EMS Board:
3. Fit the end-of-line resistor (120 Ω) between connection 42-41 for a correct RS-485
communication.
