Notes:
• When using a printer power supply other than the optional AC adaptor (PS60A-24A), be
sure that the following cautions are observed.
• Use a power supply of DC 24 V ± 5% and more than 2.0 A (5.0 A Load 10 sec. Min.) with
SELV output and LPS or Class 2 output approved by IEC60950.
• Be careful about installing the printer in an area where there is noise. Take the appropriate
measures to protect against electrostatic AC line noise, etc.
