3.3.3 Bus Decoupling Kit
The bus decoupling kit ensures mechanical xation and
electrical shielding of cables for the following control
cassette variants:
•
Control cassette with PROFIBUS.
•
Control cassette with PROFINET.
•
Control cassette with CANopen.
•
Control cassette with Ethernet.
•
Control cassette with POWERLINK.
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, Ethernet, and POWERLINK connectors and
cables.
3.3.4 Mounting
To mount the bus decoupling kit:
1. Place the horizontal decoupling plate on the
control cassette mounted on the frequency
converter and fasten the plate using 2 screws as
shown in Illustration 3.5. Tightening torque is 0.7–
1.0 Nm (6.2–8.9 in-lb).
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 3.6. Tightening torque is
0.7–1.0 Nm (6.2–8.9 in-lb).
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.
