Installation Guide
VLT® PROFINET MCA 120
VLT® AutomationDrive FC 361
1 Introduction
1.1 Purpose of this Installation Guide
This installation guide provides information for quick replacement of a VLT® PROFINET MCA 120 interface in the VLT® AutomationDrive
FC 361.
The installation guide is intended for use by qualified personnel. Users are assumed to be familiar with the VLT® drive, with PROFINET
technology, and with the PC or PLC used as a master in the system.
Read the instructions before installation and ensure that instructions for safe installation are observed.

2 Safety
2.1 Safety Precautions
WARNING
DISCHARGE TIME
The drive contains DC-link capacitors, which can remain charged even when the drive is not powered. High voltage can be
present even when the warning indicator lights are off.
Failure to wait the specified time after power has been removed before performing service or repair work could result in death
or serious injury.
Stop the motor.
-
Disconnect AC mains, permanent magnet type motors, and remote DC-link supplies, including battery back-ups, UPS, and
-
DC-link connections to other drives.
Wait for the capacitors to discharge fully. The minimum waiting time is specified in table Discharge time and is also visible
-
on the nameplate on top of the drive.
Before performing any service or repair work, use an appropriate voltage measuring device to make sure that the capacitors
-
are fully discharged.

Technical Data
3 Technical Data
3.1 Cabling Requirements
• Choose suitable media for Ethernet data transmission. CAT5e and CAT6 cables are recommended for industrial applications. Both
types are available as unshielded twisted pair and shielded twisted pair.
• Shielded cables are recommended for use in industrial environments and with drives.
• A maximum cable length of 100 m (328 ft) is allowed between the switches.
3.2 Cable Specifications
PROFINET cables used are based electrically on category 5 balanced LAN cables according to ISO/IEC 11801 Edition 2.0, Class D.
Type C cables can be used in special applications (for example, the use of trailing cables and frequently moved machine parts), even
though their design and mechanical parameters can deviate from the specifications of type A and type B cables. Still, most of the
electrical parameters (for example, impedance levels) are retained.
Highly flexible copper cables generally have the finest stranded conductors and a highly resistant polyurethane outer sheath. Various
outer sheath materials are permitted to meet the various demands regarding resistance of industrial environments and exterior/
underground laying (natural and synthetic oil, grease, coolants/lubricants, chemicals, high and low temperatures, UV radiation, and so
on).
