with the rated voltage/current and that there is sufficient circuit capacity for the power supply. 
Once verified, connect the cable firmly.

instrument operating in rated range.  To change a 
cable or add an extension cable, be sure that it can 
meet the required power ratings for this instrument. 
Any misuse with wrong or unsafe cables will void the 
warranty.
