Safety Precautions
Wiring:
1. Turn off power before wiring to minimize the risk of electrical shock.
2. Exposed conductive parts of wire can cause electrical shock. Use crimp-style terminals
with insulating sheath or insulating tape to cover the conductive parts. Also close the
terminal covers securely on the terminal blocks when wiring has been completed.
3. Operation without grounding may cause electrical shock or malfunction. Connect the
ground terminal on the T2N to the system ground.
4. Applying excess power voltage to the T2N can cause explosion or fire. Apply power of
the specified ratings described in the manual.
5. Improper wiring can cause fire, electrical shock or malfunction. Observe local
regulations on wiring and grounding.
Operation:
1. Configure emergency stop and safety interlocking circuits outside the T2N. Otherwise,
malfunction of the T2N can cause injury or serious accidents.
2. Operate the T2N 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 T2N 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 T2N for the purpose other than specified. This can
cause electrical shock or injury.
6. Do not modify the T2N and related equipment in hardware nor software. This can
cause fire, 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 T2N.
