Danfoss VLT Midi Drive FC 280 User manual

The bus decoupling kit ensures mechanical xation and
electrical screening of cables for the following control cassette
variants:
•
Control cassette with PROFIBUS.
•
Control cassette with PROFINET.
•
Control cassette with CANopen.
•
Control cassette with Ethernet.
Each bus decoupling kit contains 1 horizontal decoupling plate
and 1 vertical decoupling plate. Mounting the vertical
decoupling plate is optional. The vertical decoupling plate
provides better mechanical support for PROFINET and Ethernet
connectors and cables.

Safety Instructions
WARNING
DISCHARGE TIME
The frequency converter contains DC-link capacitors, which
can remain charged even when the frequency converter is
not powered. High voltage can be present even when the
warning LED indicator lights are o. Failure to wait the
specied time after power has been removed before
performing service or repair work can result in death or
serious injury.
•
Stop the motor.
•
Disconnect AC mains and remote DC-link power
supplies, including battery back-ups, UPS, and DC-
link connections to other frequency converters.
•
Disconnect or lock PM motor.
•
Wait for the capacitors to discharge fully. The
minimum waiting time is specied in Ta bl e 1 .2 .
•
Before performing any service or repair work, use
an appropriate voltage measuring device to make
sure that the capacitors are fully discharged.

Mounting
To mount the bus decoupling kit:
1. Place the horizontal decoupling plate on the control
cassette that is mounted on the frequency converter,
and fasten the plate using 2 screws, as shown in
Illustration 1.1. Tightening torque 0.7–1.0 Nm.
2. Optional: Mount the vertical decoupling plate as
follows:
2a Remove the 2 mechanical springs and 2
metal clamps from the horizontal plate.
2b Mount the mechanical springs and metal
clamps on the vertical plate.
2c Fasten the plate with 2 screws, as shown in
Illustration 1.2. Tightening torque 0.7–
1.0 Nm.
NOTICE
If the IP21 top cover is used, do not mount the vertical
decoupling plate, because its height aects the proper
installation of the IP21 top cover.

Both Illustration 1.1 and Illustration 1.2 show PROFINET sockets.
The actual sockets are based on the type of the control
cassette mounted on the frequency converter.
3. Push the PROFIBUS/PROFINET/CANopen/Ethernet
cable connectors into the sockets in the control
cassette.
4. 4a Place the PROFIBUS/CANopen cables
between the spring-loaded metal clamps to
establish mechanical xation and electrical
contact between the screened sections of
the cables and the clamps.
4b Place the PROFINET/Ethernet cables
between the spring-loaded metal clamps to
establish mechanical xation between the
cables and the clamps.
