A-3-2 Mounting and Removing
Connect the NS-AL002 directly to port A or port B of the PT. Two NS-AL002 Adapters
cannot be connected to ports A and B simultaneously.
Mount the Adapter by tightening and securing the mounting screws on both of the D-Sub
connectors. The correct tightening torque is 0.3 N
⋅
m. The correct tightening torque for the
terminal block is 0.5 N
⋅
m.
To remove the Adapter, loosen the screws and pull out the Adapter.
Precautions
for Safe Use
•
Always turn OFF the power to the PT before removing the Adapter.
•
Do not touch the surface or the mounted parts of the Board with bare hands.
Always discharge any static electricity from your body before handling the
Board.
Precautions
for Correct Use
•
Mount to the PT after securely connecting the cable to the terminal block.
Be sure to tighten the mounting screws on both of the D-Sub connectors. If
the screws are loose, the FG terminals of the PT and NS-AL002 will not be
connected.
