Introduction

This document is a quick installation guide for the UNITROL1005 automatic

voltage regulator. Make sure that you read and understand this document

before you install or use the product. This document is meant only as a brief

guide to the product. For detailed information on the product, refer to the User 

Manual.

Device description

UNITROL 1005 is an automatic voltage regulator (AVR) for synchronous

machines up to 80MVA. The AVR can be used for the excitation of indirectly

excited synchronous machines and motors. The AVR can also operate as a

reactive power regulator, power factor regulator or field current regulator.

Product package

Contents of the product package:

• UNITROL1005 AVR

• Special red USB cable that is used to power and to connect with the AVR.

Keep this USB cable in a safe place.

• Quick installation guide and test certificate

Make sure that all of the listed items are in the product package and that there is

no damage to the items.

Mechanical installation

For detailed information on mechanical installation, refer to the User Manual.

Install the AVR in an indoor area that is dry and dust-free, and that does not

contain volatile gases, acid fumes or similar hazards.

Examine the installation area and refer to technical data to make sure that:

• The maximum ambient temperature is in the permitted range.

• The vibration is limited and within the permitted class.

• The ingress protection and pollution degree are suitable.

• The EMC environment is suitable.

Installation requirements:

• Free space requirements:

• 10mm on the terminal side of the AVR

• 30mm on the other sides of the AVR

• Make sure that there is sufficient cooling air flow around the AVR.

• Make sure that other devices do not blow hot air on to the AVR.

• The AVR is designed to be installed with suitable hardware to an installation plate.

• Make sure that the frame of the AVR is electrically grounded (PE) to the

installation plate with a grounding wire (≥4mm2) through a mounting hole.

Use toothed washers to get a good electrical ground contact.

Installation procedure:

1. Refer to Dimensions for the mounting hole dimensions.

2. Make the appropriate holes in the installation plate.

3. Attach the AVR to the installation plate with suitable hardware, for example,

M6 screws to a torque of 10Nm. The mounting holes have a diameter of 6.5mm.

4. Make sure that there is a good electrical ground connection between the

installation plate and the AVR. The installation plate must be electrically grounded (PE).
