Panel Mounting
Remove the locking ring from the operator and check that the rubber 
gasket is in place. Insert the operator from panel front into the panel 
hole. Face the side with the projection upward, and tighten the locking 
ring using the locking ring wrench MT-001.

Notes for Panel Mounting
Using the locking ring wrench MT-001, tighten the locking ring to a 
torque of 0.88 N·m. Do not use pliers. Do not apply excessive force, 
otherwise the locking ring will become damaged.
Wiring
1.  Applicable wire size is 1.25 mm
2
 maximum.
2.   Solder the terminals using a soldering iron at 310 to 350°C for 3 
seconds maximum. Do not use flow or dip soldering. SnAgCu type 
lead-free solder is recommended. Make sure that the soldering iron 
touches the terminals only, not plastic parts. Do not apply external 
force such as bending the terminals or applying tensile force on the 
wires. 
3.   Use a non-corrosive rosin flux. To prevent the flux from entering the 
switch while soldering, face the terminals downward.
4.   Because the terminal spacing is narrow, use protective tubes or 
heat shrinkable tubes to avoid burning the wire sheath or short cir-
cuit.
5.   Apply force on the terminals in the vertical direction to the panel 
only, otherwise the terminals will be damaged.
• Turn off power to the X6 series units before installation, removal, wir-
ing, maintenance, and inspection. Failure to turn power off may cause 
electrical shocks or re hazard.
• For wiring, use wires of proper size to meet the voltage and current 
requirements and solder properly. Improper soldering may cause 
overheating and create re hazards.

Instructions
Notes for Solder/tab terminal #110
1. Use quick connect of #110 and 0.5mm tab thickness.
2. To prevent short-circuit between different poles, use protective 
tubes or heat shrink tubes.
3. Apply force on the terminals in the vertical direction to the panel 
only, otherwise the terminals will be damaged.
Contact Bounce
When the button is reset by pulling or turning, the NC contacts will 
bounce. When designing a control circuit, take the contact bounce time 
into consideration (reference value: 20 ms).
Handling
Do not expose the switch to excessive shock and vibrations, otherwise 
the switch may be deformed or damaged, causing malfunction or oper-
ation failure.
