Danfoss Metasys N2 Instruction Manual

3.3 Mechanical Installation
Prepare the mechanical installation of the adjustable
frequency drive carefully to ensure a proper result and to
avoid extra work during installation. To become familiar
with the space demands, start taking a close look at the
mechanical drawings at the end of this instruction.
3.3.1 Tools Needed
To perform the mechanical installation, the following
tools are needed:
•
Drill with 10 mm or 12 mm (0.4 or 0.5 in) drill
•
Tape measure.
•
Wrench with relevant metric sockets (7–17 mm
(0.28–0.67 in))
•
Extensions to wrench.
•
Sheet metal punch for conduits or cable
connectors in IP21/Nema 1 and IP54 units
•
Lifting bar to lift the unit (rod or tube max. Ø 5
mm (1 inch), able to lift minimum 400 kg (880
lbs).
•
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.
3.3.2
General Considerations
Wire access
Ensure proper cable access, including necessary bending
allowance. As the IP00 enclosure is open to the bottom, x
cables to the back panel of the enclosure where the
adjustable frequency drive is mounted by using cable
clamps.
CAUTION
All cable lugs/shoes must be mounted within the width
of the terminal bus bar.
Space
Ensure proper space above and below the adjustable
frequency drive to allow airow and cable access. In
addition, consider space in front of the unit to enable
opening of the panel door.
