2.3.5 Tightening Torques

For compressing the gasket between the two parts, the screws must be tightened with 2.8-3.0Nm. Tighten the screws in a
cross-over way.

2.4 Electrical Installation

The frequency converter must be wired for operation in the following manner:
• •
Wire the motor to the frequency converter output terminals.
•
Connect control and serial communication wiring.
•
Wire the AC mains to the frequency converter input terminals.
•
After power has been applied, input and motor power must be checked, and control terminals programmed for
intended functions.
This section provides detailed descriptions of the requirements and procedures to accomplish these tasks. The following
illustration shows a basic electrical connection.
