For piping, use a metal pipe.
Screw in the pipe while holding the hexagonal part with
a wrench or the like. Not doing so and using a strong force
when screwing in the pipe may cause the thread on the OX400
to rotate, resulting in damage to the internal pipe.

4.2.1 Power Supply Wiring
CAUTION
For the power supply, be sure to use the rated voltage shown on the rear panel. Connection to a
power supply with a different voltage may cause damage to the OX400. Power cord connector with
a protective ground pin is used for power supply wiring for the OX400. Be sure to securely insert the
connector of supplied power supply cord to the OX400, and connect the plug to a 3P socket with a
protective ground pin.
WARNING
Before connecting wires, be sure to remove the power plug from the socket and check that the power
is turned off in order to prevent electric shock. Furthermore, after finishing the wiring, be sure to secure
the special terminal cover with screws.
• Do not use the supplied power cord with another device.
