Nominal power supply: 400/3/50+N ± 6%
Unbalance voltage: max 2%.
CONNECTION TO THE MAINS POWER
Connecting 400/3/50 three-phase units.
Connect the phase wires to the unit's circuit breaker, respecting the sequence of the phases L1 L2 L3; the neutral is
connected to the corresponding terminal. the earth is connected to the special terminal inside the electrical panel.
CAUTION
The connection cables should be of a suitable cross-section for the power input of the unit (see the electrical data table) and
conform to the standards in force. Special care must be taken when connecting to the earth system using the special terminal
inside the control panel. The start of the line should be fitted with at least one protective device against short circuits in that part
of system.
