CSA464AE HIEE400106R0001 processor module

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 C). 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 mm2 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

Mounting Inside the Drive

 The work inside the drive should be carried out by a qualified electrician only. WARNING! Pay attention to the slowly discharging voltage of the capacitor bank and the voltages that are connected from external control circuits to the inputs and outputs of the drive. WARNING! Do not touch the printed circuit boards. The integrated circuits are extremely sensitive to electrostatic discharge.
