Checkpoint
Power supply Check that approx. 220 to 240 V AC is supplied at both ends of the
voltage power cord connections on the terminal block.
■ If 220 to 240 V AC is not supplied, check the following points.
1 Check that the earth leakage breaker is turned ON.
2 Check that the power cord is connected securely to the terminal
block.
Power supply Check that approx. 220 to 240 V AC is supplied between TAB1 and
voltage on the TAB2 (orange) on the power circuit board (JT-30P8H).

●If 220 to 240 V AC is not supplied, check the following points.
Power supply Check that approx. 220 to 240 V AC is supplied to the following
voltage on the points in the order of 1 and 2.
filter circuit board 1 Between TAB20 and TAB21 (red)
If approx. 220 to 240 V AC is not supplied, check the power
(JT-30F8)
supply voltage of the earth leakage breaker.
2 Between TAB22 and TAB23 (orange)
If approx. 220 to 240 V AC is not supplied, replace the filter
circuit board (JT-30F8).
●When 220 to 240 V AC is supplied, check the following points.
Connector dis- Check if the connector CN19 on the display circuit board (JT-
connection for 30S5R) or CN18 on the control circuit board (JT-30M8A/JT-30M8/
the display circuit JT-30M9A) is disconnected.
