Environmental Limits; Access; Fire Protection; Compliance With Regulations - Emerson Unidrive M600 Installation Manual

1.4

Environmental limits

Instructions in this guide regarding transport, storage, installation and use of the drive
must be complied with, including the specified environmental limits. Drives must not be
subjected to excessive physical force.
1.5

Access

Drive access must be restricted to authorized personnel only. Safety regulations which
apply at the place of use must be complied with.
1.6

Fire protection

The drive enclosure is not classified as a fire enclosure. A separate fire enclosure must
be provided. For further information, refer to the Drive User Guide.
1.7

Compliance with regulations

The installer is responsible for complying with all relevant regulations, such as national
wiring regulations, accident prevention regulations and electromagnetic compatibility
(EMC) regulations. Particular attention must be given to the cross-sectional areas of
conductors, the selection of fuses or other protection, and protective ground (earth)
connections.
This guide contains instruction for achieving compliance with specific EMC standards.
Within the European Union, all machinery in which this product is used must comply with
the following directives:
2006/42/EC: Safety of machinery.
2004/108/EC: Electromagnetic Compatibility.
1.8

Motor

Ensure the motor is installed in accordance with the manufacturer's recommendations.
Ensure the motor shaft is not exposed.
Standard squirrel cage induction motors are designed for single speed operation. If it is
intended to use the capability of the drive to run a motor at speeds above its designed
maximum, it is strongly recommended that the manufacturer is consulted first.
Low speeds may cause the motor to overheat because the cooling fan becomes less
effective. The motor should be installed with a protection thermistor. If necessary, an
electric forced vent fan should be used.
The values of the motor parameters set in the drive affect the protection of the motor. The
default values in the drive should not be relied upon.
It is essential that the correct value is entered in Pr 00.046 motor rated current. This
affects the thermal protection of the motor.
1.9

Mechanical brake control

The brake control functions are provided to allow well co-ordinated operation of an
external brake with the drive. While both hardware and software are designed to high
standards of quality and robustness, they are not intended for use as safety functions, i.e.
where a fault or failure would result in a risk of injury. In any application where the
incorrect operation of the brake release mechanism could result in injury, independent
protection devices of proven integrity must also be incorporated.
