4.8Tightening Torque Values for Screw Connections

These values apply to the electrical and mechanical connections.

They do not apply to the floor attachment of the system or the indi- vidual control cabinets where the floor is subject to dynamic force.

The specified torque information for the built-in units must be ob- served.
