Installing the Aries Drive Only qualified, skilled electrical technicians familiar with local safety
requirements should install this product. For service, the drive must be
returned to an authorized service center. There are no user serviceable parts
inside the chassis. In certain circumstances, opening the cover may void the
product warranty.
The Aries drive is a vented product. To prevent material spilling into the
drive, mount it under an overhang or in a suitable enclosure.
Aries products are made available under “Restricted Distribution” for use in
the “Second Environment” as described in EN 61800-3 1996, page 9. This
means only those individuals familiar with the EMC requirements of power
drive systems should install this product and that this product is designed for
connection to mains distribution networks other than low-voltage networks,
which may supply domestic premises. The drives can tolerate atmospheric
pollution degree 2, which means only dry, non-conductive pollution is
acceptable.
Aries drives have been shown to meet the requirements of both the
European LVD & EMC directives when installed according to the
recommendations given within this section. It is recommended the drive be
installed in an enclosure to protect it from atmospheric and industrial process
contaminants and to prevent operator access while it has power applied.
Metal equipment cabinets are ideally suited for housing the equipment since
they can provide operator protection, EMC screening, and can be fitted with
interlocks arranged to remove all hazardous motor and drive power when the
cabinet door is opened. Do not arrange interlocks to open circuit the motor
phase connections while the system is still powered, as this could cause
damage to the drive.
Precautions
During installation, take the normal precautions against damage caused by
electrostatic discharges. Wear earth wrist straps. A switch or circuit breaker
must be included in the installation, which must be clearly marked as the
disconnecting device and should be within easy reach of the machine
operator.
The Aries Drive has exposed high voltage terminals. In order to comply with
the safety requirements pertaining to European Compliance, and other
authorities, the drive must be mounted in such a way as to restrict access to
these terminals during normal operation.
A Safe Installation – Meeting the Requirements of the Low
Voltage Directive (LVD)
In order to comply with the requirements of the European Union’s Low
Voltage Directive, the following installation measures must be taken.
• Mains fuses must be installed on all mains input lines carrying
operating current. For more information, see “Motor Power Fuse
Information” on page 41 and page 46.
• Drive Protective Earth Conductor must be connected directly to a
reliable system safety Earth point. Total resistance from Drive’s
