1Warnings and Cautions
General
WARNING
This equipment contains dangerous voltages and controls potentially dangerous
rotating mechanical parts. Non-compliance with the Warnings or failure to follow the
instructions contained in this manual can result in loss of life, severe personal injury
or serious damage to property.
Only suitable qualified personnel should work on this equipment, and only after
becoming familiar with all safety notices, installation, operation and maintenance
procedures contained in this instruction. The successful and safe operation of this
equipment is dependent upon its proper handling, installation, operation and
maintenance.
The power supply, DC and motor terminals, the brake and thermistor cables can
carry dangerous voltages even if the inverter is inoperative. Wait at least five minutes
to allow the unit to discharge after switching off the line supply before carrying out
any installation work. It is strictly prohibited for any mains disconnection to be
performed on the motor-side of the system; any disconnection of the mains must be
performed on the mains-side of the Inverter.
When connecting the line supply to the Inverter, make sure that the terminal case of
the motor is closed. When changing from the ON to OFF-state of an operation if an
LED or other similar display is not lit or active; this does not indicate that the unit is
switched-off or powered-down.
The inverter must always be grounded. Isolate the line supply before making or
changing connections to the unit. Ensure that the inverter is configured for the
correct supply voltage. The inverter must not be connected to a higher voltage
supply.
Take particular notice of the general and regional installation and safety regulations
regarding work on dangerous voltage installation (e.g. EN 50178) as well as the
relevant regulations regarding the correct use of tools and personal protective
equipment (PPE).

CAUTION
Children and the general public must be prevented from accessing or approaching
the equipment!
This equipment may only be used for the purpose specified by the manufacturer.
Unauthorized modifications and the use of spare parts and accessories that are not
sold or recommended by the manufacturer of the equipment can cause fires, electric
shocks and injuries.
NOTICE
Keep these instructions within easy reach of the equipment and make them available
to all users.
Whenever measuring or testing has to be performed on live equipment, the
regulations of Safety Code BGV A2 must be observed, in particular § 8 "Permissible
Deviations when Working on Live Parts". Suitable electronic tools should be used.
Before installing and commissioning, please read the safety instructions and
warnings carefully and all the warning labels attached to the equipment. Make sure
that the warning labels are kept in a legible condition and replace missing or
damaged labels.
Ensure that the appropriate circuit-breakers/fuses with the specified current rating
are connected between the power supply and the inverter.
These instructions assume that the user is fully conversant with the use of the
following technologies:
- PLCs
- The commissioning software STARTER
- PROFIdrive profiles and protocols.
The commissioning procedure outlined in this manual is for Standard Inverters only -
Fail-safe commissioning is covered in the Operating Instructions.

2Installation
Command and setpoint sources ot the CU240E
The inverter is controlled and monitored per default via terminals.
Note
The command and setpoint sources can be changed in the commissioning procedure
or via Parameters P0700 and P1000.
2.1 Installing the Control Unit
The CU controls the functions of the PM. The CU cannot be used without a PM, also
the PM cannot be used without a CU.
WARNING
An inverter can be switched on unintentionally if the installation is not performed
correctly. The inverter must be started-up by personnel who are qualified and trained
in installing systems of this type.

Fitting the Control Unit to the Power Module
The Control Unit is snapped onto the Power Module as shown in the figure below. To
disconnect the CU push the release button on top of the PM.
The process of fitting the Control Unit to the Power Module is the same technique
independent from the type of G120 control unit or G120 power module.

2.2 Terminals
Overview of CU240E Terminals
The terminals are designed as cage clamps for cable cross sections from 0.2 mm2 up
to 1,5 mm2 (24 … 14 AWG). The different types are listed below:
•Digital Inputs (DI) 6
•Digital Outputs (DO) 3
•Analog Inputs (AI) 2
•Analog Outputs (AO) 2
•PTC interface 1
Cable length for I/O cables
The maximum cable length connected to the CU must not exceed 10 m (32.8 ft).
Use of unscreened cables is possible, however we recommend the use of screened
cables, in order to fulfill the EMC requirements for the CE marking.
2.3 Connecting a CU240E via USS
Description
The CU240E can be connected via terminals 29 and 30 to an RS485-USS bus system
with a maximum transfer rate of 115200 baud.
The bus termination switch is located directly beneath terminals 29 and 30.

4Commissioning
Description
When shipped from the factory the G120 inverter (control unit and power module) must
not be operated before a commissioning of the inverter has been performed.
This can be done via:
● downloading a valid parameter set from BOP or STARTER
● performing a commissioning via BOP or STARTER
For a successful operation of the inverter-motor combination, the following
prerequisites must be fulfilled:
● The rated inverter current is at least as great as the rated current of the motor.
● The power range of the inverter matches the power range of the motor.
Commissioning with the Getting Started Guide
Commissioning in the Getting Started Guide is described using STARTER via PC
Connection Kit. For other commissioning modes please refer to the Operating
Instructions of the Control Module.
The STARTER software uses a series of wizards and masks to guide the user through
the commissioning procedures for the inverter.
What do you need?
The following items are required to
commission the Inverter with STARTER:
● STARTER software is installed on
your PC
● The inverter is connected to the PC
via the PC connection cable - order
number: 6SL3255-0AA00-2AA0
