Caution: Before applying power to the valve, it is necessary to ensure the output configuration of METAFORSA module is correct. The incorrect configuration can cause the voltage application simultaneously to both channels of the valve, which may result in the module failure and/or failure of the equipment connected to it, and even a fire.

Two adjacent contact points (for example, 3, 4) are used to connect the double-pole water/gas supply valve; in these conditions the neutral wire and the ground wire are connected directly to the switchboard. The example of connection is shown in Fig.8.
