Introduction to Operating Instructions

These Operating Instructions are a tool intended for persons who are to install, operate and program the
VLT 7000 Booster.

These Operating Instructions are divided into four sections with information about VLT 7000 Booster.

Introduction to Booster:

This section tells you the advantages you can obtain by using a VLT
7000 Booster - such as AEO, Automatic Energy Optimization, RFI
filters and other HVAC-relevant functions. This section also contains
examples of application as well as information about Danfoss.

Installation:

This section tells you how to carry out mechanically correct installation
of the VLT 7000 Booster. In addition, this section includes a description
of how to ensure that the installation of your VLT 7000 Booster
is EMC-correct. Furthermore, a list is given of mains and motor
connections, together with a description of the control card terminals.

Programming:

This section describes the control unit and the software parameters for
the VLT 7000 Booster. Also included is a guide to the Quick Setup
menu, which allows you to get started on your application very quickly.

All about VLT 7000 Booster

This section gives information about status, warning and error
messages from the VLT 7000 Booster. Additionally, information is given
on technical data, service, factory settings and special conditions.

Indicates a general warning

NB!:

Indicates something to be noted by the reader
