6-4 Wiring JW-34KBM
Wire the 5V and (FG) terminals and the I/O expansion connector on the JW-34KBM basic rack panel.
- Be sure to supply 5 VDC to the expansion rack panel without power supply module, through the 5
VDC terminal block of the JW-34KBM or expansion rack panel with power supply module.
Do not reverse the polarities (+ and -) when wiring the 5 VDC terminal. Incorrect (reversed) wiring may
damage the modules or cause a fire.
- Make sure to provide a class 3 ground for FG terminal on the JW-34KBM.
- Do not place the I/O expansion cable and the 5 VDC cable in the same duct or pipe as the I/O lines
and the power lines of the JW30H.
