Danfoss 132B0369 Bus Decoupling Kit VLT Midi Drive Instruction Manual

Danfoss 132B0369 Bus Decoupling Kit VLT Midi Drive

Installation Instructions

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 CAN open.
• 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.

Items Supplied

• Horizontal decoupling plate.
• Vertical decoupling plate.
• 4 M3x6 screws.

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 specied 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 DClink connections to other frequency converters.
• Disconnect or lock PM motor.
• Wait for the capacitors to discharge fully. The minimum waiting time is specied in Table 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 aects the proper installation of the IP21 top cover.

Illustration 1.1 Fasten the Horizontal Decoupling Plate with Screws

Illustration 1.2 Fasten the Vertical Decoupling Plate with Screws

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.

1. Push the PROFIBUS/PROFINET/CAN open/Ethernet cable connectors into the sockets in the control cassette.
2. 4a Place the PROFIBUS/CAN open 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.
