2.3 Electrical Installation

Remove the four M5 cross-head screws on the inverter's cover to access the electrical terminals(see Figure 3 and Figure 4).

Notes: (1) Refer to the electrical data table for cable sizes (see section 6).

(2)We recommend introducing a `drip loop' when connecting the mains and control cables(see Figure 5).

CAUTION

The printed circuit boards contain CMOS components that are particularly sensitive to static electricity. For this reason, avoid touching the boards or components with your hands or metal objects.

IMPORTANT

Ensure that the following tightening torques are used:

Electrical terminal screws:

1.1 Nm

4.0 Nm

Gland hole covers:

1.0 Nm

*Check that the supply voltage is correct for the COMBIMASTERused by referring to the voltage code part of the order number (see section 6).
