Toa IP-A1SC15 - Removable Terminal Plug Connections

8.3. RemovableTerminalPlugConnections
Please note the following points when making connections to the control input or output terminals
using the supplied removable terminal plugs:
• Do not tin stripped wire ends with solder.
Soldered wire ends will be crushed when the terminal plug screws are tightened, leading to higher
contact resistance and potentially resulting in an abnormal rise in the temperature of the connected
parts.
• Use AWG 24 – 14 wire (ø0.5 – 1.6 mm solid wire or multi-stranded wire with a cross-sectional area
of 0.2 – 2.0 mm
2
).
• Strip the wire end back about 7 mm (0.28").
• When connecting 2 wires or a signal cable to a single terminal,
crimp them in an insulated (twin) wire ferrule to prevent their
core wires from being separated from one another. Use a
ferrule of the dimensions shown in the gure at right.
[PlugConnectionProcedure]
Step 1. Loosen the terminal screw and insert a wire.
Step 2. Tighten the screw rmly.
Note
Pull on the wire to ensure that it does not
come off.
Step 3. Insert the plug into either the control input
terminal or control output terminal.
