2. Fit the earth braid strap, supplied with the unit, between the PE faston connector and the mounting surface. Ensure there is a
good electrical connection between the mounting surface and the earth strap.
3. Connect the power input directly to the power terminals L/L1 - N/L2 (1 phase) or L/L1, N/L2, L3 (3 phase), and earth (PE) as
shown in Figure 2.2.1, using a 3-core cable for single phase units or a 4-core cable for three phase units. For the cross-section of
each core see section 8.
4. Use a 4-core screened cable to connect the motor. The cable is connected to the motor terminals U, V, W and the earth (PE)
shown in Figure 2.2.1.
Note: For operation with cables longer than 25m see section 1.3.4
5. If required, secure Faston connectors to the braking resistor leads and fit the connectors to the B+/DC+ and B- terminals at the
rear of the inverter.
Note: These connections have to be made with the inverter dismounted from the mounting surface. Care must be taken routing
the leads through the moulded clips to prevent trapping and chafing when the unit is mounted and secured to the
selected surface. Connect the control leads as shown in Figures 2.2.4 and 2.2.6.
