Safety Precautions

• Turn off power to the XW series emergency stop switch

before starting installation, removal, wiring, maintenance,

and inspection of the relays. Failure to turn power off may

cause electrical shock or fire hazard.

• Use wires of the proper size to meet the voltage and

current requirements, and solder the wires correctly. If

soldering is incomplete, the wire may heat during opera-

tion, causing fire hazard.

Instructions

Removing the Contact Block

First unlock the operator button. Grab the bayonet ring ➀

and pull back the bayonet ring until the latch pin clicks ➁,

then turn the contact block counterclockwise and pull out

Notes for removing the contact block

1. When the contact block is removed, the monitor contact

(NO contact) is closed.

2. While removing the contact block, do not exert excessive

force, otherwise the switch may be damaged.

3. An LED lamp is built into the contact block for illuminated

pushbuttons. When removing the contact block, pull the

contact block straight to prevent damage to the LED

lamp. If excessive force is exerted, the LED lamp may be

damaged and fail to light.

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 without thread on

the operator with TOP marking upward, and tighten the

locking

ring using ring wrench MW9Z-T1 to a torque of 2.0 N·m

maximum.

Notes for Panel Mounting

To prevent the XW emergency stop switch from rotating

when resetting from the latched position, use of an anti-

rotation ring (HW9Z-RL) or a nameplate is recommended.

Installing the Contact Block

First unlock the operator button. Align the small ▼ marking

on the edge of the operator with the small ▲ marking on

the yellow bayonet ring. Hold the contact block, not the

bayonet ring. Press the contact block onto the operator and

turn the contact block clockwise until the bayonet ring

clicks.

Notes for installing the contact block

Make sure that the bayonet ring is in the locked position.

Check that the two projections on the bayonet ring are

securely in place.

Wiring

Solder Terminal

1. The applicable wire size is 1.25 mm2 maximum.

2. Solder the terminal at a temperature of 310 to 350°C

within 3 seconds using a soldering iron. Sn-Ag-Cu type is

recommended when using lead-free solder. When solder-

ing, do not touch the enabling switch with the soldering

iron. Also ensure that no tensile force is applied to the

terminal. Do not bend the terminal or apply excessive

force to the terminal.

3. Use a non-corrosive rosin flux.

4. Because the terminal spacing is narrow, use protective

tubes or heat shrinkable tubes to avoid burning of wire

coating or short circuit.

PC Board Terminal

1. When mounting a contact block on a PC board, provide

sufficient rotating space for the PC board when installing

and removing the contact block.

2. When mounting an XW emergency stop switch on a PC

board, make sure that the operator is securely installed.

3. Do not solder by flow soldering. Otherwise, damage may

be caused.
