Application precautions

WARNING
Do not start the system until you check that the axes are present
and of the correct type.
The numbers of the Flexible axes will change if MECHATROLINK-

ning it in the Unit.
Not checking the program may result in an unexpected operation.
Caution
Always use the power supply voltage specified in this manual.
An incorrect voltage may result in malfunction or burning.
HARDWARE REFERENCE MANUAL
Caution
Take appropriate measures to ensure that the specified power with
the rated voltage and frequency is supplied. Be particularly careful
in places where the power supply is unstable.
An incorrect power supply may result in malfunction.
Caution
Install external breakers and take other safety measures against
short-circuiting in external wiring.
Insufficient safety measures against short-circuiting may result in
burning.
Caution
Do not apply voltage to the Input Units in excess of the rated input
voltage.
Excess voltage may result in burning.
Caution
Do not apply voltage or connect loads to the Output Units in
excess of the maximum switching capacity.
Excess voltage or loads may result in burning.
Caution
Disconnect the functional ground terminal when performing with-
stand voltage tests.
Not disconnecting the functional ground terminal may result in
burning.
