14.1 Preparation for Test Operation
14.1.1 Preliminary inspection [power OFF]
Incorrect connection of the power supply terminal, contact of the DC input wire and power supply wire, or
short-circuiting of output wires may result in serious damage.
Before applying power, check that the power supply and ground terminals are connected correctly and input/
output devices are wired properly.
14.1.2 Connection to built-in programming connector
When connecting the communication cable of a peripheral device, align the positioning mark of the cable with
that of the main unit.
TRANSPORTATION AND
STORAGE PRECAUTIONS
• Before transporting the PLC, turn on the power to the PLC to check that the BATT LED is off.
If the PLC is transported with the BATT LED on or the battery exhausted, the battery-backed data may be
unstable during transportation.
• The PLC is a precision instrument. During transportation, avoid impacts larger than those specified in the general
specifications (section 4.1).
Failure to do so may cause failures in the PLC.
After transportation, verify the operations of the PLC.
• When transporting lithium batteries, follow required transportation regulations.
(For details of the regulated products, refer to Appendix E)
Notes
The dielectric withstand voltage and insulation resistance test of the PLC should be measured in accordance with the
following procedures.
1) Remove all input/output wires and power supply wires from the PLC.
2) Connect a crossing wire to each of the PLC terminals (power supply terminal, input terminals and output
terminals) except the ground terminal.
For the dielectric withstand voltage test of each terminal, refer to the generic specifications for the product.
→ Refer to Section 4.1.
3) Measure the dielectric withstand voltage and insulation resistance between each terminal and the ground
terminal.
Dielectric withstand voltage: 1.5kV AC or 500V for 1min (The terminals vary in dielectric withstand voltage.)
Insulation resistance: 500V DC / 5MΩ or more
