For actual power usage values, refer to the power consumption figures in Table 4-7. Note It is the customer's responsibility to supply the main inlet cable and the inlet cables for the machine and UV system. The length, diameters, and cross section of the power line should be calculated according to the final position of the press to the electrical supply line. Danger The mains power supply to the installation site, all electrical power outlets, and the power line to the machine and UV system must be checked by a qualified licensed electrician for compliance with national and local authority safety requirements. The qualified licensed electrician must also issue and sign a certificate to this effect. Chapter 4 - Site Planning 31
