*2: The JW-21PU power supply module for theJW20H/30H can also be used with the JW300.
- When a power supply module is installed on an expansion rack panel, and if a power is supplied to
the power supply module on the basic rack panel without supplying power to the power supply
module on the expansion rack panel, the system detects as "input/output error" (#0160 = Error code
40) or "expansion power supply error" (#0160 = Error code 43). Make sure to supply power also to
the power supply module on the expansion rack panel.
- The power terminal block is equipped with a terminal block cover at delivery. Remove this cover
when you wire. After connecting, make sure to put the cover to the original position.
