6-3 Wiring for power supply module
In order to prevent wire wastes from dropping into the module through a ventilation hole of the power
supply module (JW-303PU, etc.) during the wiring work, keep the caution label stuck onto the upper side
of the module. Peel the caution label off of the module when all wiring work is finished.
A cover was installed on the terminal block of the power supply module at delivery. Take off a cover on
the power terminal block when wiring, and put the cover back on the terminal block when wiring work is
finished.
For wiring, use a twisted wire of over KIV1.25 square and crimp-style terminals.
Fasten the screw on the terminal block with a torque of less than 1.18 N-m.
(1) JW-301PU/31PU (AC power supply module)
- Connect the power supply input to the L terminal (LIVE: ungrounded side) and N terminal
(NEUTRAL: grounded side) while paying attention.

JW-301PU : 85 to 264 VAC

Halt output
Be sure to connect the
line to the emergency
stop circuit.
Ground line
To prevent electric shock and noise
error, be sure to separately prepare
class-D ground.
Use an insulation
transformer to reduce
noise on the power supply line.
- Wiring of halt output on the power supply module that is mounted on the expansion rack
panel is not necessary. Only the halt output on the power supply module that is mounted
on the basic rack panel should be connected to an external operation ready circuit.
- In the case where the power supply module is installed on the expansion rack panel for
operating the JW300, use one power supply system for both power supply module on the
basic rack panel and the expansion rack panel. If each power supply is wired from a
different system, the JW300 does not run when either one is switched OFF.
