NCAN-02 Installation and Start-up Guide 3-1
Chapter 3 – Mechanical Installation
Overview
This chapter contains module mounting instructions. Depending on the
drive, the module can be installed either inside or outside the drive
housing or cabinet. See the user’s manual of the drive for module
placement options.
Mounting Outside
the Drive Choose the location for the module. Note the following:
• The cabling instructions must be followed (see Chapter 4). Also, the
length of the fibre optic cables included in the option package
restrict the distance between the module and the drive.
• Observe the free space requirements for the module (min. 10 mm
from adjoining equipment or wall) and the drive (see the drive
documentation).
• The ambient conditions should be taken into account (see
Appendix D). The degree of protection of the module is IP 20.
• Module earth is connected to the mounting rail by means of an
earthing clip (see Figure 3-1). The mounting rail onto which the
option module is to be mounted must be earthed to a noiseless
earth. If the rail is not mounted on a properly earthed base, a
separate earthing conductor must be used. The conductor must be
as short as possible and the cross-sectional area must be 6 mm
2
at
least.
Note: No solid copper conductor may be used (stranded wire allowed
only).
Mounting instructions:
1. Switch off all dangerous voltages in the enclosure that the module
is to be mounted in.
2. Fasten the rail and ensure the proper earthing as described above.
3. Push the module onto the rail. The module can be released by
pulling the locking spring with a screwdriver (see Figure 3-1).
