Installing the drive
2.1
Installation considerations
Adhere to the instructions
The mechanical and electrical installation instructions
must be adhered to. Any questions or doubt should be
referred to the supplier of the equipment. It is the
responsibility of the owner or user to ensure that the
installation of the drive and any external option unit, and
the way in which they are operated and maintained,
comply with the requirements of the Health and Safety at
Work Act in the United Kingdom or applicable legislation
and regulations and codes of practice in the country in
which the equipment is used.
Motor voltage
The motor must be suitable for use with a M’Ax drive and
its required supply voltage.
Competence of the installer
The drive must be installed only by professional
assemblers who are familiar with the requirements for
safety and EMC. The assembler is responsible for
ensuring that the end-product or system complies with
all the relevant laws in the country where it is to be used.
Flash/insulation testing
The drive and RFI filter have internal electrical
components connected between the AC-supply phases
and ground. In order to avoid damaging these
components when flash or insulation testing the AC-
supply circuit and/or motor circuit, first disconnect the
drive completely from the circuit to be tested.
All imperial measurements (in feet and inches) are an
approximation of their metric translations.
Authorised access
Only authorised, trained service personnel should be allowed access to
the drive.
Installation in an enclosure
The drive must be protected against water, condensation and electrically
conductive contamination.
The drive has ingress protection rated at IP20 (in accordance with
IEC60529).
UL listing is valid when the drive is installed in a type 1 enclosure as
defined in UL50.
Fire enclosure
The drive case is not classified as a fire enclosure. When this protection
is required, the drive should be installed in a fire enclosure.
Hazardous areas
The drive not be located in a classified hazardous area unless it is
installed in an approved enclosure and the installation is certified.
Environmental
See Appendix A for UL-listing information.
See Appendix B Data for environmental requirements.
If condensation is likely to occur when the drive is not in use, an anti-
condensation heater must be installed. This heater must be switched off
when the drive is in use; automatic switching is recommended.
If the drive is to be mounted directly above any heat-generating
equipment (such as another drive), the maximum temperature of the air
immediately below the drive should be taken as the ambient temperature
for the drive.
Electromagnetic compatibility
The drive contains powerful electronic circuits which can cause
electromagnetic interference. The information and instructions in this
chapter include routine EMC precautions that will minimise the risk of
disturbance to typical industrial control equipment. These include
installing the drive in a metal enclosure as well as careful attention to the
layout of the connecting cables.
Additional precautions must be taken if any of the following apply:
•
Strict compliance with emission standards is required
•
It is known that electromagnetically sensitive equipment, such as
radio receivers, is located nearby
•
The drive is to be operated in a residential environment
The information and instructions relating to these additional precautions
are contained in the EMC emission standards sections later in this
chapter. These precautions include installing an RFI filter in the AC
supply to each drive and additional attention paid to cables and
grounding.

2.3
AC supply protection
g
The AC supply to the drive must be fitted with suitable
protection against overload and short-circuits. Table 2-3
shows recommended fuse ratings. Failure to observe
this recommendation will cause a risk of fire.
The AC supply to the drive must have a sufficiently low
impedance path to ground so that a ground fault would
cause the AC supply protection to operate.
Include a fuse of the specified rating in each phase of the AC supply.
The use of the following types of fuse is recommended:
•
Europe: Type gG HRC industrial fuses to IEC 60269 (BS88)
•
USA: CC 600VAC
