There is a voltage selector switch that allows you to configure the power supply to match your national supply voltage. This must be checked and set after receipt of the delivery. The default setting is 220 V, which causes less damage when connected to a 110 V power supply. However, the reverse setting can lead to irreversible damage.


This power supply is aimed at experienced users. If you are not familiar with the cabling in your own network, please consider an alternative power supply. All connections must be isolated to avoid short circuits and electrical shock to people who may be exposed to your printer. Please play it safe!
