1. LEGAL NOTES AND SAFETY INSTRUCTIONS
1.1 Justification
VASCAT motors contain low-voltage parts and rotating elements that make them hazardous; they also contain hot surfaces.
Users must take notice of all the hazard warning signs described in this manual (see Section 1.3).
All tasks related to the transport, connection, commissioning and maintenance must be performed by responsible, skilled
personnel (in accordance with the EN 50110-1 (VDE 0105-100) and IEC 60364 standards). Inappropriate procedures may cause
serious personal injury and material damages.
VASCAT motors may only be used for the purposes specified in Section 1.4.
Furthermore, the site conditions must meet all the requirements given on the motor nameplate and in this document.
1.2 Target readership and purpose
The purpose of the operation manual is to provide all the information required for the appropriate mounting, commissioning and
maintenance of the MAC QM motors and avoid hazards that may cause serious injury. The manual is targeted for any person or
individual who handles or is responsible for operation of the motors dealt with in the manual.
All the individuals working with MAC QM three-phase motors must have this manual at their disposal and they must follow the
relevant instructions and indications.
The operation and maintenance instructions must be read carefully before operating the machine. This will guarantee proper
operation free from hazards and complications and will extend the service life of the machine.
These service instructions provide a description of the machine and information for its proper handling and operation from
delivery to the end of its service life.
This manual must always be complete and perfectly legible.

1.3 Hazards and warning signs
The manual contains the information required for personnel safety and the prevention of material damages. All information related
to personnel safety is highlighted in general with a warning triangle; however, the hints (to avoid only material damages) are not.
Depending on the hazard level, the signs indicate hazards from major to minor as follows:
WARNING
If no preventive measures are adopted, the result may be death or serious injury.
CAUTION
If no appropriate measures are taken, the result may be serious injury.
PRECAUTION
If no appropriate measures are taken, the result may be material damages.
NB
The result may be an unwanted condition or situation if the corresponding safety instruction is not observed.
If several hazard levels are present at the same time, the most stringent instruction for each case will apply. If a safety instruction
with a warning triangle warns of personal injury, the same instruction may also contain a warning of possible material damages.
Signs indicating the type of danger Warning or Caution in the manual that may be used together with the pictograms above are
as follows:
VOLTAGE
Indicates the presence of voltage on connection terminals or live parts.
HOT SURFACE
Indicates the possibility of the contact surface having a very high temperature with the consequent risk of burns.
MOVING ROTATING PARTS
Indicates the possibility of injury and trauma caused by contact with shafts and other rotating parts.
DANGER
If no appropriate measures are taken, the result will be death or serious injury.

1.4 Intended use
WARNING
VASCAT motors have been designed for industry plants. They comply with the requirements of the harmonised standards of the
EN 60034 series.
Such pieces of equipment are devices designed to be mounted in machines in accordance with the current Machinery Directive.
Commissioning is not allowed until the end product is checked and found to be compliant with said Directive (please see, among
others, the EN 60204-1 standard).
VASCAT MAC QM motors must be used only for the applications provided in the catalogues and the related technical
documentation.
If third-party products and parts are used, they must be previously approved by VASCAT.
Proper and safe operation of the products requires their proper transportation, storage, installation, mounting, assembly, operation
and maintenance.
Allowed ambient conditions must be observed. The use of MAC QM motors in hazardous areas is strictly prohibited unless they
have been designed specifically for said circumstance, in which case the indications and warnings given in the related
documentation must be observed.
1.5 Skilled personnel
WARNING
VASCAT motors must be installed and operated in accordance with the specifications given in this document. Only skilled
personnel in the context of the manual, i.e. individuals who have the required technical know-how and skills for handling,
commissioning and starting the motors according to safety standards, shall be allowed to operate the motors.
Skilled personnel refers to those individuals who are capable of recognising the risks related to their field of activity and avoiding
the related hazards.

1.6 Disclaimer
The indications given in the manual describe the product features, but no warranty is implied.
VASCAT declines all liability for damages and operating faults caused by the following:
- Failure to follow the operating instructions.
- Damages caused by inappropriate motor handling.
- Changes made to motors without prior authorisation.
- Operating errors.
- Carrying out inappropriate work on and with the motors.
The indications that refer to procedures and the connection details provided in the manual must be considered only as proposals
and whether or not they are applicable must be studied for each case in particular. VASCAT does not guarantee their
appropriateness in any case.
The data given in this manual is reviewed regularly and subsequent editions are published when corrections are necessary.
1.7 Scope of the documentation and external references
The manual contains all the information required for the correct handling, installation (electrical and mechanical), commissioning
and subsequent maintenance of MAC QM series motors, together with the accessories required for proper operation.
It also describes the safety instructions to guarantee that no personal injuries or material damages will be caused during the
entire process.
If the motor design includes any special features (considered as non-standard), additional documentation may be necessary. In
those cases, the customer must check with VASCAT to make sure that he has all the relevant information.
This document provides no information about the technical data sheets or the specific technical data of the various MAC QM
models or their characteristic curve.
