3.2 Mechanical Installation
Preparation of the mechanical installation of the adjustable
frequency drive must be done carefully to ensure proper
results and to avoid additional work during installation.
Start by taking a close look at the mechanical drawings at
the end of this instruction manual to become familiar with
the space demands.
3.2.1 Tools Needed
To perform the mechanical installation, the following tools
are needed:
•
Drill with 0.39 or 0.47 in [10 or 12 mm] drill.
•
Tape measure
•
Wrench with relevant metric sockets (7–17mm)
•
Extensions to wrench
•
Sheet metal punch for conduits or cable
connectors in IP 21/Nema 1 and IP 54/Nema 12
drive types.
•
Lifting bar to lift the unit (rod or tube max. Ø
25mm (1 inch), able to lift minimum 400kg
(880lbs)).
•
Crane or other lifting aid to place the adjustable
frequency drive in position
•
A Torx T50 tool is needed to install the Unit Size
51IP 21/Nema 1 and IP 54/Nema 12 drive types.
3.2.2 General Considerations
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
allow the panel door to be opened.
