3. Mechanical Installation
3.1. General
The drive should be mounted in a vertical position only, on a flat, flame resistant, vibration free mounting using the integral mounting
holes or DIN Rail clip (Frame Size 2 only).
The drive must be installed in a pollution degree 1 or 2 environment only.
Do not mount flammable material close to the drive.
Ensure that the minimum cooling air gaps, as detailed in sections 3.6. Guidelines for Enclosure Mounting (IP20 Units),
3.8. Guidelines for Mounting (IP55 Units) and 3.9. Guidelines for Mounting (IP66 Units) are left clear.
Ensure that the ambient temperature range does not exceed the permissible limits for the drive given in section 10.1. Environmental.
Provide suitable clean, moisture and contaminant free cooling air sufficient to fulfil the cooling requirements of the drive.
3.2. Before Installation
Carefully Unpack the drive and check for any signs of damage. Notify the shipper immediately if any exist.
Check the drive rating label to ensure it is of the correct type and power requirements for the application.
To prevent accidental damage always store the drive in its original box until required. Storage should be clean and dry and within
the temperature range –40°C to +60°C.
3.3. UL Compliant Installation
Note the following for UL-compliant installation:
For an up to date list of UL compliant products, please refer to UL listing NMMS.E226333.
The drive can be operated within an ambient temperature range as stated in section 10.1. Environmental.
For IP20 units, installation is required in a pollution degree 1 environment.
For IP55 & IP66 units, installation in a pollution degree 2 environment is permissible.
UL Listed ring terminals / lugs must be used for all bus bar and grounding connections.
Refer to section 10.3. Additional Information for UL Approved Installations on page 71.
3.4. Installation Following a Period of Storage
Where the drive has been stored for some time prior to installation, or has remained without the main power supply present for an
extended period of time, it is necessary to reform the DC capacitors within the drive according to the following table before operation.
For drives which have not been connected to the main power supply for a period of more than 2 years, this requires a reduced
mains voltage mains voltage to be applied for a time period, and gradually increased prior to operating the drive. The voltage levels
relative to the drive rated voltage, and the time periods for which they must be applied are shown in the following table. Following
completion of the procedure, the drive may be operated as normal.
