PREPARATION & WIRING TO THE UNIT
■
POWER SUPPLY
Confirm the power input rating marked on the product.
1) Remove the terminal cover.
2) Loosen three screws at the power supply terminals.
3) Connect power input and protective earth cables to them.
4) Replace the terminal cover.
■
I/O SIGNALS
Refer to the following example of connecting CAS input sig-
nal:
1) Turn off the power supply and remove the terminal cover.
2) Connect positive signal wire to the terminal +[32] and
negative wire to −[33].
3) Replace the terminal cover.
Choose appropriate solderless terminals and wires:
Connection: M3.5 screw terminal (torque 1.0 N∙m)
Screw terminal: Nickel-plated steel
Recommended solderless terminal: R1.25-3.5
