Safety Instructions
1. General
In operation, drive converters, depending on their degree
of protection, may have live, uninsulated, and possibly
also moving or rotating parts, as well as hot surfaces.
In case of inadmissible removal of the required covers,
of improper use, wrong installation or maloperation, there
is the danger of serious personal injury and damage to
property.
For further information, see documentation.
All operations serving transport, installation and commis-
sioning as well as maintenance are to be carried out by
skilled technical personnel (Observe IEC 364 or CENELEC
HD 384 or DIN VDE 0100 and IEC 664 or DIN/VDE 0110
and national accident prevention rules!).
For the purposes of these basic safety instructions, „skilled
technical personnel“ means persons who are familiar with
the installation, mounting, commissioning and operation
of the product and have the qualications needed for the
performance of their functions.
2. Intended use
Drive converters are components designed for inclusion in
electrical installations or machinery.
In case of installation in machinery, commissioning of the
drive converter (i.e. the starting of normal operation) is
prohibited until the machinery has been proved to conform
to the provisions of the directive 2006/42/EC (Machine-
ry Safety Directive - MSD). Account is to be taken of EN
60204.
The drive converters meet the requirements of the Low-
Voltage Directive 2006/95/EC. They are subject to the har-
monized standards of the series EN 61800-5-1.
The technical data as well as information concerning the
supply conditions shall be taken from the rating plate and
from the documentation and shall be strictly observed.
3. Transport, storage
The instructions for transport, storage and proper use shall
be complied with.
The climatic conditions shall be in conformity with EN
61800-5-1 .
4. Installation
The installation and cooling of the appliances shall be in
accordance with the specications in the pertinent docu-
mentation.
The drive converters shall be protected against excessive
strains. In particular, no components must be bent or iso-
lating distances altered in the course of transportation or
handling. No contact shall be made with electronic compo-
nents and contacts.
1.7 Safety and operating instructions
Safety and operating instructions for drive converters
(in conformity with the Low-Voltage Directive 2006/95/EC)
Drive converters contain electrostatic sensitive compo-
nents which are liable to damage through improper use.
Electric components must not be mechanically damaged
or destroyed (potential health risks).
5. Electrical connection
When working on live drive converters, the applicable nati-
onal accident prevention rules (e.g. VBG 4) must be com-
plied with.
The electrical installation shall be carried out in accordance
with the relevant requirements (e.g. cross-sectional areas
of conductors, fusing, PE connection). For further informa-
tion, see documentation.
Instructions for the installation in accordance with EMC
requirements, like screening, earthing, location of lters
and wiring, are contained in the drive converter documen-
tation. They must always be complied with, also for drive
converters bearing a CE marking. Observance of the limit
values required by EMC law is the responsibility of the ma-
nufacturer of the installation or machine.
6. Operation
Installations which include drive converters shall be equip-
ped with additional control and protective devices in ac-
cordance with the relevant applicable safety requirements,
e.g. act respecting technical equipment, accident preven-
tion rules etc.. Changes to the drive converters by means
of the operating software are admissible.
After disconnection of the drive converter from the voltage
supply, live appliance parts and power terminals must not
be touched immediately because of possibly energized
capacitors. In this respect, the corresponding signs and
markings on the drive converter must be respected.
During operation, all covers and doors shall be kept
closed.
7. Service and maintenance
The manufacturer’s documentation shall be followed.

1) The values refer percentage to the output rated current IN
2) The output frequency is to be limited in such way that 1/10 of the switching frequency is not exceeded.
3) Rated operation corresponds to UN=400 V; fSN; fA=50 Hz (typically value)
4) On reaching the temperature Tdr the switching frequency is step down. The switching frequency is increased again on cooling down to temperature
Tur.
5) At rated voltages > 460 V multiply the rated current with factor 0.86
6) The voltage at the motor is dependent on the series-connected units and on the control method (example see chapter A.1 in the annex)
The technical data are for 2/4-pole standard motors. With other pole numbers the inverter must be
dimensioned onto the motor rated current. Contact KEB for special or medium frequency motors.
The service life of the frequency inverter with intermediate voltage circuit depends on the current load
of the electrolytic capacitors in the intermediate circuit. The use of mains chokes can increase the
service life of the condensators to a considerable extent, especially when connecting to „hard“ power
systems or when under permanent drive load (continuous duty). For continuous duty (S1) drives with
a medium duty of >60%, KEB provided the use of mains chokes with a terminal voltage (Uk) of 4%.
The term "hard" power system means that the nodal point power (SNet) of the mains is very high (>>
200) compared to the output rated power of the inverter (SA).

KEB COMBIVERT units contain dangerous voltages which can cause
death or serious injury.
The KEB COMBIVERT can be adjusted in such a way that energy regene-
ration into the supply net is possible at regenerative operation also during
mains power failure. Therefore a dangerous high tension can exist in the
unit after switching off the supply system.
Before working with the unit check the isolation from supply by mea-
surements in the unit. Motors are to be secured against automatic
starting.
Care should be taken to ensure correct and safe operation to minimise risk
to personnel and equipment.
The terminal strips meet the requirements on IEC 60947-7-1

The COMBIVERT G6-C corresponds to the inverter type
A1. This type can be supplied both by mains and via DC
terminals. The starting current limiting is arranged before
the DC link. When using as DC output parallel connected
frequency inverters must have their own starting current
limiting at the DC voltage input.
3.2.1.1 Wiring instructions
Never exchange the mains and motor cables.
Some countries demand that the PE-terminal is directly connected to the terminal box
(not over the mounting plate).

3.2.2 Connection of the motor
3.2.2.1 Selection of the motor cable
The correct cabling as well as the motor cable play an important part in case of low power
in connection with long motor line lengths. Ferrite cores and low-capacitance cable (phase/
phase<65 pF/m, phase/screen < 120 pF/m) at the output have the following effects:
•longer motor line lengths
•lower abrasion of the motor bearings by leakage currents
•improved EMC characteristics
3.2.2.2 Motor line length at operation with DC voltage
The maximum motor line length at DC operation is basically dependent on the capacity of
the motor cable. The internal lter is not active at DC operation. External measures must be
taken here, if necessary. The following data apply for operation under nominal rating condi-
tions.

3.2.2.3 Cable-fed disturbances depending on the motor line length at AC supply
The maximum motor line length is depending on the capacity of the motor cable as well as
on the EMC emitted interference. The following data apply for operation under nominal rating
conditions.

The line length can be extend signicant by using motor chokes or lters. KEB recom-
mends the use of motor chokes or lters for a line length upto 50 m. Motor chokes or
lters are absolutely necessary upto 100 m.
3.2.2.4 Motor cable cross-section
The conductor cross-section of the motor cable is dependent on the output current, the cable
according to manufacturer's data, as well as the VDE regulations.
3.2.2.5 Interconnection of the motor
The connecting-up instructions of the motor manufacturer are generally valid !
Protect motor
against voltage
peaks !
Inverters switch at the output with du/dt ≤ 5kV/µs. Voltage peaks
that endanger the insulation system at the motor can occur espe-
cially in case of long motor cables (> 15 m).
A motor choke, a dv/dt-lter or sine-wave lter can be used for
protection of the motor.

Only "intrinsically safe" braking resistors are per-
missible for this operation, since these resistors
interrupt themselves at fault such as safety fuse
without re risk. The delivered intrinsically safe
braking resistors by KEB are described in the inst-
ruction manual 00G6N1Z-0010.
