Important Information
Purpose of the Manual
This manual complements the ET 200X Distributed I/O Device manual. It describes all the functions of the EM 300 motor starters. The manual does not
deal with functions that have general applicability to the ET 200X. You will find
descriptions of these in the ET 200X Distributed I/O Device manual.
The information in this manual and in the ET 200X Distributed I/O Device
manual allows you to run the ET 200X with a EM 300 motor starter as a DPSlave on the PROFIBUS.
Target group
The manual describes the hardware of the EM 300 motor starters and is aimed
at configuration engineers, commissioning engineers and maintenance personnel, who use the ET 200X with PLC functionality.
It consists of chapters containing instructions and reference chapters.
Delivery package
This delivery package (order number 6ES7 198-8FA01-8BA0) consists of 4 manuals with the following contents:

2.1 Rules for Wiring
Warning
Dangerous high voltage! Take care to avoid electric shock and injuries from
burns. Always deenergize the system and the device before carrying out any
work.
Selecting the motor connecting cables
The core cross section of the motor connecting cables must match the given
environmental conditions. The cross section is governed by:
• the nominal current set on the unit,
• the method of cable laying,
• the ambient temperature,
• the insulation material of the motor connecting cable (PVC, rubber).
For PVC motor connecting cables laid in cable ducts, the following maximum
current carrying capacities apply according to environment temperature:
T

Motor starter EM 300 with braking contact
The 400 V power supply for the motor and the 24 V DC power supply for the
brake are fed to the load through a common cable and connector. There is a danger of voltage overspill if the cable is flattened. Do not therefore connect loads
with degree of protection "extra-low voltage" to the braking circuit.
In order to avoid voltage overspill in case of fault the supply voltage for the
brake must be drawn from a power supply unit with safe electrical isolation
(PELV).
Motor starter EM 300 without braking contact
The braking supply voltage of motor starters without a 24 V braking contact is
internally not looped through. The 24 V DC braking voltage must then be drawn
from the power supply unit again.
Unused connections
Seal unused connections with caps, only then is degree of protection IP 65
guaranteed (order number 3 RK1 902-0CK00 (1 piece) or 3 RK1 902-0CJ00
(10 pieces).
