Installing the LED Unit (with Removable

Contact Block)

Align the to of the LED unit with the TOP marking on the

contact block. Push the LED unit into the contact block.

Wiring

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 ter-

minal. 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.

Solder/Tab Terminal #110

1. Use #110 receptacles for 0.5mm-thick tabs.

2. Because the terminal spacing is narrow, use protective tubes

or heat shrinkable tubes of 0.5mm minimum in thickness.

3. Do not apply force on the terminals in the direction

other than vertical to the mounting panel, otherwise the

terminals will be damaged.

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 XA emergency stop switch on a PC

board, make sure that the operator is securely installed.

About PC Board and Circuit Design

1. Use PC boards made of glass epoxy copper-clad laminated

sheets of 1.6 mm in thickness, with double-sided through

hole.

2. PC boards and circuits must withstand rated voltage and

current, including the instantaneous current and voltage

at switching.

3. The minimum applicable load is 5V AC/DC, 1 mA. This value

may vary according to the operating environment and load.

4. Within the 2.8

∗ mm areas shown in the figure below,

terminals touch the PC board, resulting in possible short

circuit on the printed circuit. When designing a PC board

pattern, take this possibility into consideration.

Installing Insulation Terminal Cover

To install the terminal cover (XA9Z-VL2), align the TOP

marking on the terminal cover with TOP marking on the

contact block, and press the terminal cover toward the

contact block.

Note: For wiring, insert the wires into the holes in the terminal cover before

soldering.

Contact Bounce

When the button is reset by pulling or turning, the NC main

contacts will bounce. When pressing the button, the NO

monitor contacts will bounce.

When designing a control circuit, take the contact bounce

time into consideration (reference value: 20 ms).

Nameplate

When anti-rotation is not required, remove the projection

from the nameplate using pliers.

Handling

Do not expose the switch to excessive shock and vibration,

otherwise the switch may be deformed or damaged,

causing malfunction or operation failure.
