Upgrading from the SJ300 Series<br />
The SJ300 series inverter is upwardly compatible with the <strong>SJ700</strong> series inverter. Therefore, you can:<br />
- mount the control circuit terminal block board of the SJ300 series in the <strong>SJ700</strong> series without removing<br />
the connected cables,<br />
- copy the parameter settings from the SJ300 series into the <strong>SJ700</strong> series, and<br />
- use the option boards mounted in the SJ300 series for the <strong>SJ700</strong> series without removing the connected<br />
cables.<br />
(1) Control circuit terminal block board<br />
You can mount the control circuit terminal<br />
block board of the SJ300 series into the<br />
<strong>SJ700</strong> series. Note, however, that the<br />
backing plate is incompatible.<br />
(Procedure for replacing the control circuit<br />
terminal block board)<br />
As shown in the figure on the right, the<br />
fixing screw locations on the control circuit<br />
terminal block board are common to the<br />
SJ300 and <strong>SJ700</strong> series.<br />
To remove and install the control circuit<br />
terminal block board, follow the steps 1) to<br />
5) described below.<br />

Precautions:<br />
Use care to prevent the control circuit terminal block board from twisting when removing or mounting it.<br />
Otherwise, the board guide pins and connector pins may be damaged.<br />
Do not pull the cables connected to the control circuit terminal block board when you remove the<br />
board from the SJ300 series.<br />
Do not forcibly insert the board into the mounting slot. Make sure that the board is correctly fitted onto<br />
the board guide pins and the connectors are correctly fitted to each other.<br />

Removing the control circuit terminal block board from the<br />
SJ300 series<br />
1) Remove two fixing screws from the control circuit terminal<br />
block board.<br />
2) Pull the control circuit terminal block board straight toward<br />
you to remove it from the SJ300 series.<br />
Precautions:<br />
Pull out the board slowly.<br />
Be careful not to bend the connector pins.<br />
Be careful not to break the board guide pins.<br />
Mounting the removed control circuit terminal block board in<br />
the <strong>SJ700</strong> series<br />
3) Remove the original control circuit terminal block board<br />
from the <strong>SJ700</strong> series beforehand (as instructed in steps<br />
1) and 2)).<br />
4) Insert the control circuit terminal block board removed<br />
from the SJ300 series straight into the slot along the<br />
board guide pins and connector pins until it touches the<br />
fixing-screw seats.<br />
Precautions:<br />
Push in the board slowly.<br />
Be careful not to bend the connector pins.<br />
Be careful not to break the board guide pins.<br />
5) Secure the control circuit terminal block board with two<br />
fixing screws.<br />
Precaution:<br />
Be sure to fix the board with the two fixing screws.<br />
