1.4 Product Overview

1.4.1 Intended Use

The drive is an electronic motor controller intended for:

•Regulation of motor speed in response to system feedback or to remote commands from external controllers. A power-drive system consists of the drive, the motor, and equipment driven by the motor.

•System and motor status surveillance.

The drive can also be used for motor protection.

Depending on the configuration, the drive can be used in standalone applications or form part of a larger appliance or installation.

The VLT® Decentral Drive FCD 302 is designed for decentral mounting, for example, in the food and beverage industry, or for other material handling applications. With the FCD 302, it is possible to reduce costs by placing the power electronics decentrally. Central panels are then rendered obsolete, saving cost, space, and effort for installation and wiring. The basic design is service-friendly with a pluggable electronic part and a flexible and spacious wiring box. It is easy to change electronics without the need for rewiring.

Installation environment: The drive is allowed for use in residential, industrial, and commercial environments in accordance with local laws and standards.

For both small and large units, the service switch is optional. The switch is shown mounted on the motor side. Alternatively, the switch can be on the mains side or omitted.

For the large unit, the circuit breaker is optional. The large unit can be configured with either service switch or circuit breaker, not both. The illustration shown is not configurable in practice, but shows the respective positions of components only.

4.6 Terminal Types

Motor, control, and mains terminals are spring loaded (CAGE-CLAMP) type.

1.Open the contact by inserting a small screwdriver into the slot above the contact, as shown in Illustration 14.

2.Insert the stripped wire into the contact.

3.Remove the screwdriver to fasten the wire into the contact.
