For the optimal connection of Automatic PFC System, are necessary some simple operation that have to be absolutely respected.
Following, are showed the steps that is necessary to follow for the installation:
1.
Earth Connection of Secondary of Current Transformer (C.T.)
2.
Connection of Automatic PFC System with optimal size of cables, referred to power indicated on the plate.
3.
Power Supply: Three-Phase + PE (excluding special request)
4.
Connection of Power Cables on General MCCB, respecting the sequence of Phases.
In case of Switch-OFF of Automatic PFC System during the normal operation, please be sure, before open the General MCCB, that all
Capacitor Banks are switched-off, following the instruction (please check MAN Mode)
C.T. must be positioned on (R – L1) Phase, on the top of all loads present on the Power Line that supply the
Automatic PFC System
During the connection if Automatic PFC System, must be respected the sequence of Phases (R-L1) – (S-L2) –
(T-S3)
That condition, can be easily verified using a Voltmeter: measuring, between the Phase where C.T. is positioned (R-L1) and
the Phase connected to the clamp R of Switch-Disconnector of Automatic PFC System, the Voltage must be “0”
The positioning of C.T. is absolutely necessary for the optimal operation of Automatic PFC System.
