1. Mains connection
The units are factory connected to 400 V 50/60 Hz. They also can be used on 230 V 50/60 Hz and 500 V
50/60 Hz mains. The wiring instruction for reconnection is located inside of the machines near the input
terminal (460V 50/60Hz option).
Important! In case the machines are used with 230 V mains voltage, the mains
cable delivered must be replaced by one with a bigger cross section.
