Ac Power Voltage Setting; Method Of Application Voltage; Changing Method Of Voltage And Discriminate Terminal Of Transformer - JPI JP-33 Service Manual

Technical Support
Part III AC power voltage setting (220V or 240V)
This revision adapt to after Jun 1. 2003. Version 5.01.
Please check and correct the Voltage for the processor, 250V? / 220V? / 240V?
1. New applicant Transformer: see attachment Drawing 1
Before Change) AC In-Put: 110volt, 220volt
After Change)
AC In-Put: 220volt, 240volt
JP-33 of 220voltage field area has dual AC input 220volt, 240volt.
How can use?
- If field AC-voltage is 210volt ~ 240volt: use 220V terminal
- If field AC voltage is 240volt ~ 260volt: use 240V terminal
2. Method of Application Voltage: see attachment Drawing 2
