1 Installation and Usage

1.1 Description

This installation guide explains how to install and use the USB-based VLT® Mains-Free Interface.

1.2 Item Supplied

•

VLT® Mains-Free Interface (code number: 132B9222)

1.3 Product Overview

Illustration 1: VLT® Mains-Free Interface

The connection between the VLT® Mains-Free Interface and a PC is based on a USB 2.0 interface. A Mini-B USB connector is located on the front side, and a standard drive connector is located on the back side.

Both VLT® Mains-Free Interface and the drive get current from the PC USB ports, thus the drive is mains free when the VLT® MainsFree Interface is installed on the drive.

•

For drives of enclosure size H1–H5 and I2–I4, the required current is within the standard capability of a single USB port, and a single USB type A connector can be used.

•

For drives of enclosure size H6–H10 and I6–I8, more than 500 mA current is required (500 mA is the maximum standard current a USB port can deliver). It is recommended to use a double USB type A cable for connection to a PC. It is possible for the drive to obtain the required current via both of the USB ports (the 2nd USB port is marked with Auxiliary power only).

See

Illustration 2 for the recommended cable examples.
