6.12.4 Basic schematic diagrams
Refer to 6.1.4 Installing Internal Options (OPC-VG1- ) and wire and connect the FRENIC-VG.
• Improper connections may result in disasters, such as electric shocks or fires. Qualified electricians should
carry out wiring. Turn OFF the breaker on the power supply side for electric shock prevention in the case of
touching the electric circuit during connection work.
Do not touch the smoothing capacitors soon after the breaker is turned OFF, because the smoothing capacitors
will store charge for a while and an electric shock will be received. Check with a multimeter that the DC
voltage on the inverter is low enough after the CHARGE lamp of the inverter is turned OFF.
• Do not use the product that is damaged or lacking parts. Otherwise, injury and damage may result.
Incorrect handling in installation/removal jobs could cause a failure.

Note:
The shielded wire should be basically earthed. If
strong inductive noise interferes with the
FRENIC-VG, however, the influence of the
noise may be suppressed by connecting the
shielded wire to the 0-V line.
