There is a voltage-selector switch so configure the PSU to match your national supply voltage which must be checked and set upon receipt of the supply. The default setting is 220v which is less likely to cause damage if plugged into a 110v supply, however the reverse may cause irreversible damage. 

Friendly advice

This part is aimed at experienced users, if you are not comfortable wiring in your own mains then please consider an alternative supply. All terminals must be insluated to avoid short-circuit and risk of electrocution to anyone that may be exposed to your printer. Please play safe!
