Electricity Supply Requirements - Valmar SWEETY 60 TTi Handling, Operating And Maintenance Manual

4.3 ELECTRICITY SUPPLY REQUIREMENTS

Prior to connecting the appliance to the power source, the voltage and the
maximum power current allowed in the network must be checked and the
appliance must be protected externally with FUSES and the MAIN SWITCH.
Permitted voltage of three-phase appliances (400/50/3):
nominal voltage
400V
Permitted voltage of three-phase appliances (230/50/3, 230/60/3):
nominal voltage
230V
Permitted voltage of one-phase appliances (230/50/1):
nominal voltage
230V
The diameter of each phase conductor must be of an appropriate dimension
(corresponding to the power of the fuses). It is also necessary checked the
frequency.
The MAIN SWITCH must be installed in the immediate vicinity of the appliance,
where it must be easily visible, accessible to the operator and appropriately
marked.
Magnetothermic differential FUSES (slot ≥ 3 mm) of appropriate dimensions
must be installed between the electricity network and the MAIN SWITCH.
