NIBA-01 Installation and Start-up Guide3-1Chapter 3 – Mechanical InstallationOverview This chapter contains module mounting instructions. Depending on thedrive, the module can be installed either inside or outside the drivehousing or cabinet. See the user’s manual of the drive for moduleplacement options.Mounting Outsidethe DriveChoose the location for the module. Note the following:• The cabling instructions must be followed (see Chapter 4). Also, thelength of the fibre optic cables included in the option packagerestrict the distance between the module and the drive.• Observe the free space requirements for the module (min. 10 mmfrom adjoining equipment or wall) and the drive (see the drivedocumentation).• The ambient conditions should be taken into account (seeAppendix C). The degree of protection of the module is IP 20.• Module earth is connected to the mounting rail by means of anearthing clip (see Figure 3-1 below). The mounting rail onto whichthe option module is to be mounted must be earthed to a noiselessearth. If the rail is not mounted on a properly earthed base, aseparate earthing conductor must be used. The conductor must beas short as possible and the cross-sectional area must be 6 mm2 atleast.Note: No solid copper conductor may be used (stranded wireallowed only).Mounting instructions:1. Switch off all dangerous voltages in the enclosure that the moduleis 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 bypulling the locking spring with a screwdriver (see Figure 3-1).Figure 3-1 Mounting and removing the module.Earthing Clips
