Safety Precautions
Operation:
1. Configure emergency stop and safety interlocking circuits outside the T1/T1S.
Otherwise, malfunction of the T1/T1S can cause injury or serious accidents.
2. Operate the T1/T1S 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 T1/T1S before turning on power to the loads. Failure to do so may
cause unexpected behavior of the loads.
5. Do not use any modules of the T1/T1S for the purpose other than specified. This can
cause electrical shock or injury.
6. Do not modify the T1/T1S and related equipment in hardware nor software. This can
cause fire, electrical shock or injury.
7. Configure the external circuit so that the external 24 Vdc power required for transistor
output circuits and power to the loads are switched on/off simultaneously.
Also, turn off power to the loads before turning off power to the T1/T1S.
8. Install fuses appropriate to the load current in the external circuits for the outputs.
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 T1/T1S and related equipment.
