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 the work related to the transport, connection, start-up and maintenance must be performed by responsible,
qualified personnel (in accordance with the EN 50110-1 (VDE 0105-100) and IEC 60364 standards). Incorrect
procedures may cause serious personal injury and material damages.
VASCAT motors may only be used for the purposes specified in section 0.
Furthermore, the conditions in the place where they are used must meet all the requirements given on the
specifications plate and in this document.
1.2 Users and purpose
The purpose of this instructions manual is to provide all the information required for the correct assembly, start-up
and maintenance of the MAC R motors and avoid hazards that may cause serious injury. This manual is for any
person or individual working with the motors to which it refers or who assume responsibility for their operation.
All the individuals working with three-phase MAC R motors must have this manual at their disposal and they must
follow the relevant instructions and indications.
The service instructions must be read carefully before using the machine. This will guarantee correct operation
free from hazards and complications and will extend the service life of the machine.
These service instructions give a description of the machine and information on its correct 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
This manual contains the information required for personal safety and the prevention of material damages. All the
information that refers to personal safety is highlighted in general with a warning triangle; however, the
informative notes (to avoid only material damages) are not. Depending on the hazard level, the signs indicate
hazards from major to minor as follows:
WARNING
This means that if the appropriate preventive measures are not adopted, the result will be death or serious
injury.
PRECAUTION
This means that if the appropriate preventive measures are not adopted, the result may be serious injury.
PRECAUTION
This means that if the appropriate preventive measures are not adopted, the result may be material damages.
NB
This means that the result may be an unwanted status or situation if the corresponding safety instruction is not
observed.
In the case of various hazard levels at the same time, the strictest security instruction will prevail in all
circumstances. If a safety instruction with a warning triangle warns of personal injury, the same instruction may
also contain a warning of possible material damages.
The signs that indicate the type of hazard (warning or precaution in this manual), which may be used in
conjunction with the above pictograms, are as follows:
VOLTAGE
Indicates the existence 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 properties caused by contact with shafts and other rotating parts.
DANGER
This means that if the appropriate preventive measures are not adopted, the result will be death or serious injury.

1.4 Intended use
WARNING
VASCAT motors are to be used in industrial installations. They comply with the requirements of the harmonised
standards of the EN 60034 series.
Said units are parts designed to be mounted on machines in accordance with the current machines directive.
Start-up 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).
MAC R motors by VASCAT must be used only for the applications provided in the catalogues and the
associated technical documentation.
If third-party products and parts are used, they must be previously approved by VASCAT.
The correct and safe operation of the products requires their correct transport, storage, installation, assembly,
operation and maintenance.
The allowed ambient conditions must be observed. The use of MAC R motors in potentially explosive
atmospheres is strictly prohibited unless they have been designed specifically for said circumstance, in which
case the indications and warnings given in the associated documentation must be observed.
1.5 Qualified personnel
WARNING
VASCAT motors must be installed and operated in accordance with the specifications given in this document.
Only qualified personnel are authorised to intervene when, in accordance with the manual, they have all the
technical know-how and skills required to handle, start up and connect the motors in accordance with safety
standards.
Qualified personnel refers to the individuals who are capable of recognising the risks associated with their field
of activity and avoid associated hazards.

1.6 Disclaimer
The indications given in this manual describe the product specifications but do not guarantee them.
VASCAT declines all liability for damages and operating faults caused by the following:
- Failure to follow the operating instructions.
- Damages caused by incorrect operation of the motor.
- 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 included in this 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
This manual contains all the information required for the correct handling, assembly (electrical and mechanical),
start-up and subsequent maintenance of MAC R series motors, together with the accessories that are necessary
for correct 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 involves any type of special work (considered as non-standard), additional documentation may be
necessary. In said case, 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 R models or their characteristic power and torque curves.
To obtain said information, please log on to the VASCAT website at http://www.vascat.com.
