SINAMICS G110

1 Overview

1.1 The SINAMICS G110
     The SINAMICS G110s are a range of frequency inverters for controlling the speed of three phase AC motors, incorporating the CPM 110 controlled power module.
The various models available range from 120 W to 3.0 kW single-phase input. The inverters are microprocessor-controlled and use state-of-the-art Insulated Gate BipoIar Transistor (IGBT) technology. This makes them reliable and versatile. A special pulse-width modulation method with selectable pulse frequency permits quiet motor operation. Comprehensive protective functions provide excellent inverter and motor protection.
     The SINAMICS G110 CPM110 with its default factory settings is ideal for a large range of simple V/f motor control applications. Using the comprehensive range of programmable parameters provided with the inverter, the unit can be adapted for a wide range of applications. Parameters can be changed using either USS communications or the Basic Operator Panel (BOP).
     The SINAMICS G110 is available in two variants; the Analog controlled variant and the USS controlled variant utilizing RS485 protocol. They are available as filtered and unfiltered inverters including a “Flat Plate” version which completes the range. They can be used in both 'stand-alone' applications as well as being integrated into 'Automation Systems'.

4. Electro-Magnetic Compatibility (EMC)

4.1 Electro-Magnetic Compatibility (EMC)
     All manufacturers / assemblers of electrical apparatus which “performs a complete intrinsic function and is placed on the market as a single unit intended for the end
user” must comply with the EMC directive EC/89/336. There are two routes for the manufacturer/assembler to demonstrate compliance:

4.1.1 Self-Certification
     This is a manufacturer's declaration that the European standards applicable to the electrical environment for which the apparatus is intended have been met. Only
standards that have been officially published in the Official Journal of the European Community can be cited in the manufacturer's declaration.

4.1.2 Technical Construction File
     A technical construction file can be prepared for the apparatus describing its EMC characteristics. This file must be approved by a ‘Competent Body’ appointed by the
appropriate European government organization. This approach allows the use of standards that are still in preparation.

Note:
     The SINAMICS G110 inverter is designed to be used only by professional end users with EMC knowledge. It is not designed for users that do not have EMC
knowledge. These operating instructions give sufficient information which enables the professional end user to implement all the necessary measures to ensure electromagnetic compatibility.

DIN Rail Mounting Kit

     The DIN Rail Mounting Kit is an optional accessory for the SINAMICS G110 inverter.
The kit consists of the following items:
 - 1 x Metal base plate
 - 6 - FSA, 8 - FSB x M4 screws (maximum torque 2.0 Nm [17.7 lbf.in])
 - 2 x Saddle-clamps
 - 1 - FSA, 2 - FSB x DIN Rail fixing bolt.
