Mechanical installation

This chapter describes how to use all mechanical details to install the
drive. The drive is intended to be installed in an enclosure. Key features
of this chapter include:
• Through hole mounting
• High IP as standard or Through-panel mounting
• Enclosure sizing and layout
• Option module installing
• Terminal location and torque settings
3.1

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
WARNING
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
WARNING
system complies with all the relevant laws in the country
where it is to be used.
Enclosure
The drive is intended to be mounted in an enclosure which
prevents access except by trained and authorized
personnel, and which prevents the ingress of contamination.
WARNING
It is designed for use in an environment classified as
pollution degree 2 in accordance with IEC 60664-1. This
means that only dry, non-conducting contamination is
acceptable.
3.2

Planning the installation

The following considerations must be made when planning the installation:
3.2.1 Access
Access must be restricted to authorized personnel only. Safety
regulations which apply at the place of use must be complied with.
The IP (Ingress Protection) rating of the drive is installation dependent.
For further information, refer to section 3.9 Enclosing size 5 to 6 drive for
high environmental protection on page 37
3.2.2 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
• Contamination with any form of dust which may restrict the fan, or
impair airflow over various components
• Temperature beyond the specified operating and storage ranges
• Corrosive gasses
NOTE
During installation it is recommended that the vents on the drive are
covered to prevent debris (e.g. wire off-cuts) from entering the drive.

3.2.3 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, refer to section 3.6 Enclosure for standard
drives on page 34.
3.2.4 Electrical safety
The installation must be safe under normal and fault conditions.
Electrical installation instructions are given in Chapter 4 Electrical
installation on page 45.
3.2.5 Fire protection
The drive enclosure is not classified as a fire enclosure. A separate fire
enclosure must be provided.
For installation in the USA, a NEMA 12 enclosure is suitable.
For installation outside the USA, the following (based on IEC 62109-1,
standard for PV inverters) is recommended.
Enclosure can be metal and/or polymeric, polymer must meet
requirements which can be summarized for larger enclosures as using
materials meeting at least UL 94 class 5VB at the point of minimum
thickness.
Air filter assemblies to be at least class V-2.
The location and size of the bottom shall cover the area shown in Figure
3-1. Any part of the side which is within the area traced out by the 5°
angle is also considered to be part of the bottom of the fire enclosure.
Figure 3-1 Fire enclosure bottom layout
The bottom, including the part of the side considered to be part of the
bottom, must be designed to prevent escape of burning material - either
by having no openings or by having a baffle construction. This means
that openings for cables etc. must be sealed with materials meeting the
5VB requirement, or else have a baffle above. See Figure 3-2 for
acceptable baffle construction. This does not apply for mounting in an
enclosed electrical operating area (restricted access) with concrete floor.
