4. CONNECTIONS
4.1. Removable Terminal plug Connection
Notes
• Use the screwdriver supplied with the SX-2000SM when connecting the removable terminal connector.
• Do not use a micro screwdriver. Sufficient torque is not given to the screws when tightening them, and
connections may not be secured.
• Avoid soldering stranded or shielded cable, as contact resistance may increase when the cable is tightened
and the solder is crushed, possibly resulting in an excessive rise in joint temperatures.
• When connecting 2 cables or a shielded cable to a single terminal,
use a ferrule terminal with an insulation sleeve to crimp the cables
because such cable conductors could become loose.

wiring procedures
Procedures below are for the removable terminal plug with fixing screws.
Step 1. Wiring the supplied removable terminal plug.
1-1. loosen the terminal screws to insert the wire.
1-2. tighten the terminal screws.
Ensure that the wire does not break free when
pulled.
If the wire does pull free, repeat the connection
procedure from the start.
Step 2. Insert the wired terminal plug into the
corresponding terminal block in the unit's rear
panel.
Step 3. Tighten the fixing screw.
Notes
• Do not reverse Steps 1 and 2 above. Force is applied to the connected receptacle pins while tightening the
terminal screw and they may be damaged, resulting in bad connector contact.
• When detaching the terminal plug, pull it straight out. Pulling it out at an angle may cause the terminal plug or
terminal block to break.
