How to fit and setup the device
Page 11 from 66
If CYKY or other thick and hard cables cannot pass through current transformers easily, use flexible cables to
extend the existing connections. When fitting the current sensing module do not press hard on it. You may
damage the module.
Tip:
Individual phase wires may pass through the current sensing module from either direction. The direction of
currents may be configured in the control software.
Figure 3: Three-phase connection with low tariff signal circuit for CombiWATT mode. Current sensing module is placed at the facility’s
supply cable coming from the distribution box where main energy meter is located. The connected loads use only real surpluses
produced by PV-plant. All 6 loads are connected, 4 of them through the recommended SSRs RGC(S)1A manufactured by Carlo Gavazzi.
