6.2 Mechanical Installation
Preparation for the mechanical installation of the
adjustable frequency drive must be done carefully to
ensure a proper fit and to avoid additional work during
installation. The mechanical drawings in
provide more information about the
space requirements.
6.2.1 Tools Needed
To perform the mechanical installation, the following
tools are needed:
•
Drill with 0.4 or 0.5 in [10 mm or 12 mm] drill
bits.
•
Measuring tape.
•
Wrench with relevant metric sockets (7–17 mm
[0.28–0.67 in]).
•
Wrench extensions.
•
Sheet metal punch for conduits or cable
connectors in IP21 (NEMA 1) and IP54 (NEMA 12)
units.
•
Lifting bar to lift the unit (rod or tube max. Ø1 in
[25 mm], able to lift minimum 880 lbs [400 kg]).
•
Crane or other lifting aid to place the adjustable
frequency drive in position.
•
Use a Torx T50 tool to install the E1 in IP21 and
IP54 enclosure types.
6.2.2 General Considerations
Wire Access
Ensure that proper cable access is present including the
necessary bending allowance. As the IP00 enclosure is
open to the bottom, cables must be fixed to the back
panel of the enclosure where the adjustable frequency
drive is mounted.
NOTICE!
All cable lugs/shoes must mount within the width of the
terminal bus bar.
Space
Ensure proper space above and below the adjustable
frequency drive to allow airflow and cable access. In
addition, space in front of the unit must be considered to
enable opening of the door of the panel.
