Safety Precautions

Operation:

1. Configure emerg ency stop and safety interlocking circuits outside the T1/T 1S.
Otherwise, malfunction of the T1/T 1S can cause inj ury or serious accidents.
2. Operate t he T1/T1S and t he r elated modules with closing the terminal covers. Keep
hands away fr om t er minals 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/T 1S for the purpose other than specif ied. This can
cause electrical shock or injury.
6. Do not modify the T1/T 1S and r elat ed 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 req uir ed for tr ansist or
output circuits and power to the loads are switched on/of f simultaneously.
Also, turn off power to t he loads before tur ning off power to the T1/ T1S.
8. Install fuses appropriate t o t he load cur rent 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 cont act
can cause malf unct ion or dam age to the T1/T1S and related equipment.
