VLT® AutomationDrive FC 361

Overview

1.1 Introduction
This instruction describes the VLT® General Purpose I/O MCB 101 for use in the VLT® AutomationDrive FC 361, expanding the number of inputs/outputs in the drive.
The VLT® General Purpose I/O MCB 101 includes 3 digital inputs, 2 analog inputs, 2 digital outputs, and 1 analog output.
1.2 Items Supplied

• VLT® General Purpose I/O MCB 101.

Safety

2.1 Safety Precautions

WARN I NG
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.

Table 1: Discharge Time

Voltage [V]	Power range [kW (hp)]	Minimum waiting time (minutes)
380–480	90–315 kW (125–450 hp)	20

General Technical Data

3.1 Galvanic Isolation
Digital/analog inputs are galvanically isolated from other inputs/outputs on the VLT® General Purpose I/O MCB 101 and in the control card of the drive.
Digital/analog outputs in the VLT® General Purpose I/O MCB 101 are galvanically isolated from other inputs/outputs on the VLT® General Purpose I/O MCB 101, but not from those on the control card of the drive.3.2 Digital Inputs – Terminal X30/1-4

Installation

4.1 Mounting the Control Cables Procedure

1. Make sure that the power to the drive is disconnected.
2. Remove the front cover from the drive.
3. Remove the LCP (local control panel) or blind cover, and then remove the LCP cradle from the drive.
4. Fit the VLT® General Purpose I/O MCB 101 option card into slot B.
5. Connect the control cables and relieve the cable by the enclosed cable strips.
6. Remove the knock out in the LCP cradle, so that the option fits under the LCP cradle.
7. Fit the LCP cradle.
8. Fit the LCP or blind cover in the LCP cradle.
9. Fit the front cover on the drive.
10. Connect power to the drive.
11. Set up the input/output functions in the corresponding parameters according to the technical data.
