To easily remove the Snap-in Legend Plate from the Legend

Plate Frame mounted to the panel, insert a Tool with a thin tip

into the space between the Snap-in Legend Plate and the

Legend Plate Frame.

The Snap-in Legend Plate is easily removed by pressing the

Snap-in Legend Plate from the back of the Legend Plate Frame.

The Legend Plate Frame is made of acrylic resin, which is easily

damaged by shock. Be sure to handle the Legend Plate Frame

with care.

ENGRAVING METHOD

Material: Acrylic

Engrave the characters directly on the matted side of the Snap-in

Legend Plate.

The characters must be engraved no deeper than 0.5 mm.

Apply alcohol-based paint coating to the engraved characters.

If the Snap-in Legend Plate is transparent, engrave the

mirror-written characters on the back of the Snap-in Legend Plate

and apply paint coating to the characters. Then apply paint

coating of a different color to the remaining part of the Snap-in

Legend Plate.

MOUNTING THREE-THROW SPACER

Press and secure the two protruding portions of the Three-throw

Spacer to the two indented portions of the inner side of the

control panel.

Precautions

WARNING

Do not apply a voltage between the incandescent lamp and

the terminal that is greater than the rated voltage. If the incan-

descent lamp is broken, the Operational Units may pop out.

Always turn OFF the power and wait for 10 minutes before

replacing the incandescent lamp. If the lamp is replaced

immediately after the power is turned OFF, the remaining heat

may cause burns.

CORRECT USE

Mounting

Always make sure that the power is turned OFF before mounting,

removing, or wiring the Switch, or performing maintenance.

Do not tighten the mounting ring more than necessary using tools

such as pointed-nose pliers. Doing so will damage the mounting ring.

The tightening torque is 0.98 to 1.96 N • m {10 to 20 kgf • cm}.

The panel thickness is 1 to 5 mm.

Wiring

After wiring the Switch, maintain an appropriate clearance and

creepage distance.

When DC-specific LEDs are used, wire the Switch so that the X1

terminal is positive.

Terminal screws must be Phillips or slotted M3.5 screws with a

square washer.

The tightening torque is 1.08 to 1.27 N • m{11 to 13 kgf • cm}.

Single wires, stranded wires, and crimp terminals can be

connected to the Switch.

Operating Environment

The IP65 model is designed with a protective structure so that it

will not sustain damage if it is subjected to water from any

direction to the front of the panel.
