Safety Note
The voltage of the frequency converter is dangerous whenever connected to mains. Incorrect
installation of the motor, frequency converter or fieldbus may cause damage to the equipment,
serious personal injury or death. Consequently, the instructions in this manual, as well as
national and local rules and safety regulations, must be complied with.
Safety Regulations
1. The frequency converter must be disconnected from mains if repair work is to be carried out. Check
that the mains supply has been disconnected and that the necessary time has passed before removing
motor and mains plugs.
2. The [OFF] key on the control panel of the frequency converter does not disconnect the equipment
from mains and is thus not to be used as a safety switch.
3. Correct protective earthing or grounding of the equipment must be established, the user must be
protected against supply voltage, and the motor must be protected against overload in accordance
with applicable national and local regulations.
4. The earth leakage currents are higher than 3.5 mA.
5. Protection against motor overload is not included in the factory setting. If this function is desired,
set par. 1-90 to data value ETR trip or data value ETR warning .
Note: The function is initialised at 1.16 x rated motor current and rated motor frequency. For the
North American market; the ETR functions provide class 20 motor overload protection in accordance
with NEC.
6. Do not remove the plugs for the motor and mains supply while the frequency converter is
connected to mains. Check that the mains supply has been disconnected and that the necessary time
has passed before removing motor and mains plugs.
7. Please note that the frequency converter has more voltage inputs than L1, L2 and L3, when load
sharing (linking of DC intermediate circuit) and external 24 V DC have been installed. Check that all
voltage inputs have been disconnected and that the necessary time has passed before commencing
repair work.
Warning against Unintended Start
1. The motor can be brought to a stop by means of digital commands, bus commands, references or a
local stop, while the frequency converter is connected to mains.
If personal safety considerations make it necessary to ensure that no unintended start occurs, these
stop functions are not sufficient.
2. While parameters are being changed, the motor may start. Consequently, the [OFF] key must
always be activated.
3. A motor that has been stopped may start if faults occur in the electronics of the frequency
converter, or if a temporary overload or a fault in the supply mains or the motor connection ceases.
Warning:
Touching the electrical parts may be fatal - even after the equipment has been disconnected
from mains.
Also make sure that other voltage inputs have been disconnected, such as external 24 V DC, load
sharing (linkage of DC intermediate circuit), as well as the motor connection for kinetic back up.
Please take note of discharge times and further safety guidelines from the section: “Safety and
conformity”, in the respective Design Guide (MG.33.Ax.yy).

Technical Overview
EtherNet/IP™ was introduced in 2001 and today is the most developed, proven and complete
industrial Ethernet network solution available for manufacturing automation.
EtherNet/IP is a member of a family of networks that implements the Common Industrial Protocol
(CIP™) at its upper layers. CIP encompasses a comprehensive suite of messages and services for a
variety of manufacturing automation applications, including control, safety, synchronization, motion,
configuration and information. As a truly media-independent protocol that is supported by hundreds of
vendors from around the world, CIP provides users with unified communication architecture
throughout the manufacturing enterprise.
EtherNet/IP provides users with the network tools to deploy standard Ethernet technology for
manufacturing applications while enabling Internet and enterprise connectivity.
Assumptions
These operating instructions are under the conditions that the Danfoss EtherNet/IP option is used in
conjunction with a Danfoss FC 100/200/300 frequency converter, inclusive that the installed controller
supports the interfaces described in this document and that all the requirements stipulated in the
controller, as well as the frequency converter, are strictly observed along with all limitations herein.
Hardware
This manual relates to the EtherNet/IP option MCA121, type no. 130B1119 (un-coated) and 130B1219
(coated).
Background Knowledge
The Danfoss EtherNet/IP Option Card is designed to communicate with any system complying with the
CIP EtherNet/IP standard. Familiarity with this technology is assumed.
Issues regarding hardware or software produced by other manufacturers, including commissioning
tools, are beyond the scope of this manual, and are not the responsibility of Danfoss.
For information regarding commissioning tools, or communication to a non-Danfoss node, please
consult the appropriate manuals.

How to Install Option in Frequency Converter
Items required for installing a fieldbus option in the frequency converter:
-The fieldbus option
- Fieldbus option adaptor frame for the FC 100/200/300. This frame is deeper than the standard
frame, to allow space for the fieldbus option beneath
- Strain relief (only for A1 and A2 enclosures)
Instructions:
-Remove LCP panel from the FC 100/200/300.
-Remove the frame located beneath and discard it.
- Push the option into place. The Ethernet connectors must be facing upwards.
-Remove both knock-outs on the fieldbus option adaptor frame.
-Push the fieldbus option adaptor frame for the FC 100/200/300 into place.
-Replace the LCP and attach cable
N.B.:
Do not strip the Ethernet cable and ground it via the strain relief-plate!
The grounding of screened Ethernet cable is done through the RJ-45 connector on the option.
N.B.:
After installing the MCA121 option, be aware of the following parameter settings:
Par. 8-01 Control Site [2] Controlword only or [0] Digital and ctrl. word
Par. 8-02 Control Word Source [3] Option A

Topology
The MCA121 features a build-in Ethernet-switch, thus having two Ethernet RJ-45 connectors.
This enables the possibility for connecting several EtherNet/IP options in a line topology as an
alternative to the typical star-topology.
The two ports are equal, in the sense that they are transparent for the option. If only one connector is
used, either port can be used.
Star topology
Line topology
Note: For line topology please refer to section: “Recommended design rules”
In a line topology all drives must be powered, either by mains or by their 24 V DC option cards,
for the build-in switch to work.
