Safety Precautions

Maintenance:

!CAUTION

1.Do not charge, disassemble, dispose in a fire nor short-circuit the batteries. It can cause explosion or fire. Observe local regulations for disposal of them.

2.Turn off power before removing or replacing units, terminal blocks or wires. Failure to do so can cause electrical shock or damage to the T3H and related equipment.

3.Replace a blown fuse with a specified one. Failure to do so can cause fire or damage to the T3H.

4.Perform daily checks, periodical checks and cleaning to maintain the system in normal condition and to prevent unnecessary troubles.

5.Check by referring “Troubleshooting” section of the T3 User’s Manual - Hardware, when operating improperly. Contact Toshiba for repairing if the T3H or related equipment is failed. Toshiba will not guarantee proper operation nor safety for unauthorized repairing.

6.The contact reliability of the relays used in the relay output module will reduce if the switching exceeds the specified life. Replace the module if exceeded.

7.Replace the battery every 2 years to maintain the T3H’s program and data normally.

8.Do not modify the T3H and related equipment in hardware nor software. This can cause fire, electrical shock or injury.

9.Pay special attention for safety if you attempt to measure circuit voltage at the T3H’s terminal.

10.Turn off power before replacing modules. Failure to do so can cause electrical shock or damage to the T3H and related equipment.

If you attempt to replace an I/O module while power on (by using on-line I/O replacement function), carefully check for safety.
