•When performing electrical and earthing works, be sure to comply with the 'technical standards of electrical installations' and the 'wiring regulations' in the local regulations.

•Tighten the terminal block screw to 1.2-1.8 N•m (1.2-1.8 kgf•cm).

NOTE

•Each wire is labelled with the corresponding terminal number.

•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: 60245 IEC66/CENELEC: H07RN-F, IEC: 60245 IEC57 CENELEC: H05RN-F, IEC: 60227 IEC53: H05VV-F)

•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.
