Use shield cable (Category 5; less than 50pF/m) for noisy environmental site.
Power supply cords of parts of appliances for outdoor use shall not be lighter than polychloroprene sheathed flexible cord. Code designation IEC: 60227 IEC53/CENELEC:
Power & Communication cable shall not exceed 30m.
CAUTION
For the terminal block wiring, use a wire with a ring terminal socket only. Regular wires without a ring terminal socket may become a hazard due to overheating of the electrical contact during installation.
If you need to extend the pipe, be sure to extend the cable, too. The maximum length of each of the cable and pipe used should not exceed 15 metres (✴✴18✴✴) and 20 metres (✴✴24✴✴).
Do not connect two or more different cables to extend the length. This connection may cause fire.
Fasten the screws for the wire holders.
