4.1 Transportation
The device should be transported in the same way as new devices of this type. If the original box or another
protection (e.g. corks) is not available, it is necessary to secure the device against shocks, vibrations and
moisture on one's own, using other equivalent methods.
4.2 Installation
The Control Unit Module MOD CNV PK420 is designed for installation inside control cabinets on the DIN35
rail or inside a terminal box according to the installation position as shown in Figure 2, The installation
place should be accessible only for authorized personnel and, as far as possible, access of third-party
persons must be prevented. Reasonable elevation of the installation place is recommended so that to
make the device easily accessible for maintenance and repair. Locations with excessive moisture should be
avoided.
All wiring should be made with the use of YTKSY, OMY, LiYY or similar cables with sufficient cross-section of
cores see Table 5. Maximum runs for the cable sections to wire the PK420 converter to a Control Unit, with
consideration of cable core cross-section, a listed in Table 4.
