You may use unshielded cable for connecting the mains terminals. The phases of the mains supply
and the earth have to connect to the referring terminals. Cable inlet have to put through one of the
3 cable glands.
Sizes of cable glands: P = 0,55 up to 3 kW: 3 x M20x1.5;
P = 4 up to 7,5 kW: 2 x M20x1.5; 1 x M25x1.5
Tightening torques: L1, L2, L3: 0,55 up to 4 kW: 0,5 ... 0,6 Nm
5 up to 7,5 kW: 1,2 ... 1,5 Nm
Earth Screw (at any powers): 3,4 Nm
Cover screws (at any powers ): 2,2 ... 2,4 Nm
Prefuses max.: P = 0,55 up to 3 kW: 16 A
P = 4 up to 7,5 kW: 25 A
Protecting equipment: Use ELCB relays of type B with leakage currents of 100mA
(ELCB relays of type A are not allowed for direct current content (DC)
in the fault current and power-up with short charging current to earth)

Terminals for data communication and control signals
Communication to the Compact Drive is realized via terminal block X100. Drive control is possible
via terminal block X101.
