Safety Precautions
Operation:
A WARNING
1. Configure emergency stop and safety interlocking circuits outside the T3. Otherwise,
malfunction of the T3 can cause injury or serious accidents.
A
CAUTION
2. Operate the T3 and the related modules with closing the terminal covers. Keep hands
away from terminals while power on, to avoid the risk of electrical shock.
3. When you attempt to perform force outputs, RUN/HALT controls, etc. during operation,
carefully check for safety.
4. Turn on power to the T3 before turning on power to the loads. Failure to do so may
cause unexpected behavior of the loads.
5. Set operation mode switches of the T3 and I/O modules. Improper switch settings may
cause malfunction of the T3 and related equipment.
6. Do not use any modules of the T3 for the purpose other than specified. This can
cause electrical shock or injury.
7. Configure the external circuit so that the external power required for output modules
and power to the loads are switched on/off simultaneously.
Also, turn off power to the loads before turning off power to the T3.
8. Install fuses appropriate to the load current in the external circuits for the relay output
modules. Failure to do so can cause fire in case of load over-current.
9. Check for proper connections on wires, connectors and modules. Insufficient contact
can cause malfunction or damage to the T3 and related equipment.
10. Turn off power immediately if the T3 is emitting smoke or odor. Operation under such
condition can cause fire or electrical shock.
Also unauthorized repairing will cause fire or serious accidents. Do not attempt to
repair. Contact Toshiba for repairing.
