Installing the Drive
4.1
Safety information
Follow 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.
Competence of the installer
The Drive must be installed 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.
4.2
Planning the installation
The following considerations must be made when planning the installation:
Access
Access must be restricted to authorised personnel only. Safety regulations which
apply at the place of use must be complied with.
Environmental protection
The Drive must be protected from:
•
moisture, including dripping water or spraying water and condensation. An anti-
condensation heater may be required, which must be switched off when the Drive
is running.
•
contamination with electrically conductive material
•
temperature beyond the specified operating and storage ranges
Cooling
The heat produced by the Drive must be removed without its specified operating
temperature being exceeded. Note that a sealed enclosure gives much reduced
cooling compared with a ventilated one, and may need to be larger and/or use internal
air circulating fans. For further information on enclosure design, please refer to the
Commander SE Advanced User Guide.
Electrical safety
The installation must be safe under normal and fault conditions. Electrical installation
instructions are given later in this chapter.
Fire protection
The Drive enclosure is not classified as a fire enclosure. A separate fire enclosure
must be provided.
Electromagnetic compatibility
Variable speed Drives are powerful electronic circuits which can cause
electromagnetic interference if not installed correctly with careful attention to the layout
of the wiring.
Some simple routine precautions can prevent disturbance to typical industrial control
equipment.
