Software update

System installation and assembly

Before connecting the system, you must:

  • site the sensor and actuators (if not pre-installed), set the sensors and actuators;
  • site the module and power supply.

Note: The module must be installed near the power supply voltage source.

CAUTION!

  1. AC power voltage must be provided to the system input through the circuit breaker assembly. It should be installed close to the power supply.
  2. The load is applied through the circuit breaker assembly. It can be both common – for all groups, and individual – for each  group (fig. 3,4).

Fig. 3

Fig.4

Notes:

  1. The power of circuit breaker assembly must comply with the load capacity;
  2. Nothing else than the phase conductors can be connected to the module, the neutral wire is connected separately.

Typical diagram of METAFORSA MF-10.A module connection is shown in fig. 5.

Fig. 5 Typical connection diagram

Connection of the actuators

Connection of the lights/electric contactor/heating thermal actuator
Fig. 6 Such actuators as light, electric contactor, heating thermal actuator should be switched on any of the outputs С1 – С10, the neutral wire and the ground wire should be connected directly to the switchboard. The example of connection is shown in fig.6.
Connection of single-pole water/gas supply valve
Caution: Before applying power to the load, make sure that the output configuration of METAFORSA module is correct. The incorrect configuration or incorrect connection can cause the module failure and/or failure of the equipment connected to it, and even a fire.
Fig. 7 The single pole water/gas supply valve is connected to any of the outputs of C1 – C10, the (neutral wire and the ground wire are connected directly to the switchboard. The example of connection is shown in fig.7.
Connection of double-pole water/gas supply valve
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.
Fig. 8 Two adjacent contact points of the group (for example, C3, C4) 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.
