4 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. If it is a requirement that authorised
personnel manually adjust drive settings while power is applied, then the drive itself
must meet the requirements of IP20. See section 3.2 General data on page 12 for
details.
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
