DeviceNet is a low-level network that standardises
communications between industrial devices (sensors, limit
switches, motor controls) and high-level devices
(controllers). DeviceNet systems can be congured to
operate in a master-follower or a distributed control
architecture using peer-to-peer communication.
The DeviceNet interface is designed to communicate with
any master abiding by the DeviceNet standard.

Safety
VLT® DeviceNet MCA 104
2 Safety
2.1 Safety Symbols
The following symbols are used in this manual:
WARNING
Indicates a potentially hazardous situation that could
result in death or serious injury.
CAUTION
Indicates a potentially hazardous situation that could
result in minor or moderate injury. It can also be used to
alert against unsafe practices.
NOTICE
Indicates important information, including situations that
can result in damage to equipment or property.
2.2 Qualied Personnel
Correct and reliable transport, storage, installation,
operation, and maintenance are required for the troublefree and safe operation of the frequency converter. Only
qualied personnel are allowed to install or operate this
equipment.
Qualied personnel are dened as trained sta, who are
authorised to install, commission, and maintain equipment,
systems, and circuits in accordance with pertinent laws and
regulations. Additionally, the qualied personnel must be
familiar with the instructions and safety measures
described in these operating instructions.
2.3
Safety Precautions
WARNING
HIGH VOLTAGE
Frequency converters contain high voltage when
connected to AC mains input, DC supply, or load sharing.
Failure to perform installation, start-up, and maintenance
by qualied personnel can result in death or serious
injury.
Installation, start-up, and maintenance must be
•
performed by qualied personnel only.
WARNING
UNINTENDED START
When the frequency converter is connected to AC mains,
DC supply, or load sharing, the motor may start at any
time. Unintended start during programming, service, or
repair work can result in death, serious injury, or
property damage. The motor can start with an external
switch, a eldbus command, an input reference signal
from the LCP or LOP, via remote operation using MCT 10
Set-up Software, or after a cleared fault condition.
To prevent unintended motor start:
Disconnect the frequency converter from the
•
mains.
Press [O/Reset] on the LCP before
•
programming parameters.
The frequency converter, motor, and any driven
•
equipment must be fully wired and assembled
when the frequency converter is connected to
AC mains, DC supply, or load sharing.
WARNING
DISCHARGE TIME
The frequency converter contains DC-link capacitors that
can remain charged even when the frequency converter
is not powered. Failure to wait the specied time after
power has been removed before performing service or
repair work, can result in death or serious injury.
Stop the motor.
•
Disconnect the AC mains and remote DC-link
•
power supplies, including battery back-ups,
UPS, and DC-link connections to other
frequency converters.
Disconnect or lock the PM motor.
•
Wait for the capacitors to discharge fully before
•
performing any service or repair work. The
duration of waiting time is specied in the
relevant frequency converter operating
instructions, Chapter 2 Safety.
WARNING
LEAKAGE CURRENT HAZARD
Leakage currents exceed 3.5 mA. Failure to ground the
frequency converter properly can result in death or
serious injury.
Ensure the correct grounding of the equipment
•
by a certied electrical installer.

Safety Installation Guide
WARNING
EQUIPMENT HAZARD
Contact with rotating shafts and electrical equipment
can result in death or serious injury.
Ensure that only trained and qualied personnel
•
perform installation, start-up, and maintenance.
Ensure that electrical work conforms to national
•
and local electrical codes.
Follow the procedures in this manual.
•
CAUTION
INTERNAL FAILURE HAZARD
An internal failure in the frequency converter can result
in serious injury, when the frequency converter is not
properly closed.
Ensure that all safety covers are in place and
•
securely fastened before applying power.

3.1 Safety Instructions
33
See chapter 2 Safety for general safety instructions.
3.2 EMC-compliant Installation
To obtain an EMC-compliant installation, follow the
instructions provided in the relevant frequency converter
operating instructions and design guide. Refer to the
eldbus master manual from the PLC supplier for further
installation guidelines.
3.3 Grounding
Ensure that all stations connected to the eldbus
•
network are connected to the same ground
potential. When there are long distances between
the stations in a eldbus network, connect the
individual station to the same ground potential.
Install equalising cables between the system
components.
Establish a grounding connection with low HF
•
impedance, for example by mounting the
frequency converter on a conductive back plate.
Keep the ground wire connections as short as
•
possible.
Establish electrical contact between the cable
•
screen and the frequency converter enclosure by
using metal cable glands or by using the clamps
provided on the equipment.
Use high-strand wire to reduce electrical
•
interference.
3.4
Cable Routing
NOTICE
EMC INTERFERENCE
Use screened cables for motor and control wiring, and
separate cables for eldbus communication, motor
wiring, and brake resistor. Failure to isolate eldbus
communication, motor, and brake resistor cables can
result in unintended behaviour or reduced performance.
Minimum 200 mm (7.9 in) clearance between power,
motor, and control cables is required. For power sizes
above 315 kW, it is recommended to increase the
minimum distance of 500 mm (20 in).
NOTICE
When the eldbus cable crosses a motor cable or a brake
resistor cable, ensure that the cables cross at an angle of
90°.

3.5 Mounting
1. Check whether the eldbus option is already
mounted in the frequency converter. If already
mounted, go to step 6. If not mounted, go to
step 2.
2. Remove the LCP or blind cover from the
frequency converter.
3. Use a screwdriver to remove the front cover and
the LCP cradle.
4. Mount the eldbus option. Mount the option
with the connector facing up for top cable entry
(see Illustration 3.3), or with the connector facing
down for bottom cable entry (see Illustration 3.4).
If an MCB option is installed, only top cable entry
is possible.
5. Remove the knock-out plate from the new LCP
cradle.
6. Mount the new LCP cradle.

Wiring Procedure for Enclosure Types A1-A3
1. Mount the eldbus connector on the eldbus
option (terminal V-, CAN_L, Drain, CAN_H, V+).
For top cable entry, mount the supplied EMC
bracket on top of the frequency converter with 2
screws.
2. Prepare the eldbus cable by stripping a section
of the cable insulation, so that the cable screen
contacts the EMC bracket. Keep the unshielded
wire as short as possible. For cable specications,
refer to chapter 3.7.1 Cable Specications.
3. Connect the eldbus cable wires to the terminals
according to the colour code of the wires, see
Illustration 3.8.
4. Position the stripped cable between the spring
loaded metal clamps, to establish mechanical
xation and electrical contact between cable
screen and ground.
