Handling Precautions
Installation precautions
When installing this unit, care should be given to the following points to prevent noise and
electromagnetic wave interference from other equipment.
1. Do not pass lead and connection cables through the same ducts as power lines.
2. Be sure to install the unit at least 0.5 m (20") or more away from high voltage or large
current sources or high-power relays.
3. Absolutely do not bring the unit near magnets or sources of electromagnetic waves.
Note
•Magnet chucks and other sources of magnetic force of approx. 600×10–4T (600 G)
should be kept at least 50 mm (2") or more away from the side surfaces and 100 mm (4")
or more away from the opening surfaces of the scale's steel chassis.
•If the unit must be installed close to sources of magnetic force, be sure to implement
adequate electromagnetic shielding countermeasures.
Installation place precautions
1. Mount the scale for more precise positioning as closely as possible to the workpiece or to
the object being measured.
(The farther the scale is mounted from workpiece, the greater the mechanical errors grow.)
2. The scale unit should be used within an ambient temperature range of 0 to 40°C. Avoid
locations where the scale is exposed to direct sunlight and heat sources such as motors.
3. Do not place anything on the mounted scale, or step on it: excessive force to the scale
causes trouble.
4. Never install the scale in locations such as places where the scale could be exposed
directly to coolant liquid or to coolant in mist form.

Hinweise zur Handhabung
Installationshinweise
Beachten Sie bei der Installation dieses Gerätes die folgenden Punkte, um die Einstreuung von
Rauschen und elektromagnetischen Wellen von anderen Geräten zu verhüten.
1. Verlegen Sie Zuleitungskabel und Verbindungskabel nicht zusammen mit Starkstromkabeln.
2. Halten Sie bei der Installation des Gerätes mindestens 0,5 m Abstand von Hochspannungs-,
Starkstromquellen oder Hochleistungsrelais.
3. Bringen Sie das Gerät auf keinen Fall in die Nähe von Magneten oder Quellen elektromagnetischer Wellen.
Achtung
•Magnetische Futter oder andere Magnetkraftquellen von ungefähr 600×10–4T ( 600 G) sollten
mindestens 50 mm von den Seitenflächen und mindestens 100 mm von den Öffnungen des
Stahlgehäuses des Maßstabs entfernt gehalten werden.
•Falls das Gerät in der Nähe von Magnetkraftquellen installiert werden muß, treffen Sie unbedingt
angemessene Maßnahmen zum Schutz vor elektromagnetischer Beeinflussung.
Hinweise zum Installationsort
1. Um eine möglichst präzise Positionierung zu erzielen, empfiehlt es sich, den Maßstab
möglichst nahe am Werkstück oder zum messenden Objekt einzubauen. (Je weiter der
Maßstab vom Werkstück entfernt eingebautwird, desto größer wird mechanische Fehler.)
2. Verwenden Sie die Maßstabseinheit innerhalb eines Umgebungstemperaturbereiches
von 0 bis 40°C. Einbauorte vermeiden, wo der Maßstab direkter Sonneneinstrahlung und
Wärmequellen, wie z.B. Motoren, ausgesetzt ist.
3. Nichts auf den angebauten Maßstab legen oder darauf treten: übermäßig starke
Einwirkung von Kräften auf den Maßstab erzeugt Störungen.
4. Montieren Sie den Maßstab auf keinen Fall an Stellen, an denen er direkt mit
Kühlmittelflüssigkeit oder Kühlsprühnebel in Berührung kommen kann.

These indicate the effective movement range over
which accuracy is assured with respect to the slider
center.
Note
When mounting and using the scale unit, be sure to
operate the unit within this range. Using the scale unit
in excess of the effective movement range may
damage the unit.

3. Mounting Method
3-1. Mounting Precautions
3-1-1. Checking the mounting method
Check that the scale unit can be mounted in the relative
position shown in the Fig. 3-1.
*Do not mount the scale in any other direction since
difficulties with servicing and maintenance may arise.
(Mounting position B is available only when the scale can
be protected from cutting oil and chips. (See “3-1-4”))
When mounting the scale vertically, be sure to mount the
scale slider on the opposite side of a workpiece or cutting
tool.

3-1-2. Setting the operating range
•The measuring length of the scale is the distance between
the measuring length marks (D) at both ends of the scale.
•Mount the scale in such a position that the slider center
moves within these measuring length marks.
•A leeway (10 mm (0.39") on the left and right) is provided
for the slider movement. Take special care not to move
the slider beyond this limit or the scale may be damaged.
3-1-3. Protection of the head cable
The head cable and scale come as a single integrated unit.
Take care not to pull the head cable forcefully or bend it
repeatedly or the cable may break.
3-1-4. Mounting a protective cover
If the scale is mounted in a location where it may be
exposed directly to chips or cutting oil, it is recommended
that a protective cover such as the one shown in Fig. 3-4 be
installed so that the scale is not exposed to the outside as
far as possible. This will help to maintain the scale's
performance.
Slider center
Measuring length mark
Mount the scale so that the slider center moves within this range.
(Effective movement range)
Fig. 3-3 Operating range
•Mechanical limiting devices (stoppers, etc.) are required
for sliders which move in excess of the effective
movement range of the scale unit. In these cases, be
sure to take the appropriate measures before mounting
the scale unit.

3-3. Mounting Procedure
Precautions
The procedures for mounting the scale unit are described
below.
For the scale unit, the only disassembly process during the
mounting work is removing the slider holder. (See “3-4-3”.)
Do not disassemble other locations.
The scale unit is comprised of precision mechanical and
electromagnetic parts, so applying excessive force will
have a large effect on the unit's performance and service
life. Therefore, take care not to apply excessive force when
mounting the scale unit.
In addition, when carrying the unit, the scale body and
slider should be held together. Take care not to carry the
scale by the head cable or interface unit.

3-4-1. Mounting of scale
〈1〉When the mounting surface already meets
parallelism and flatness requirements
When the scale mounting surface is finished and meets the
parallelism and flatness specifications below, just mount
the scale. (For scales of L<1250 mm (49"), use two M4×10
hex socket head cap screws and two plain washers (M); for
scales of L≧1250 mm (49"), use three M4×10 hex socket
head cap screws and three plain washers (M). Tightening
torque: 350 N·cm/35 kgf·cm)
Flatness of A, B surfaces
Parallelism of A, B surfaces to
machine table movement
Provide the range shown in Fig. 3-5 for surface A.
The above tolerances suppose no quick change in the
surfaces and no obstacle in the way between the right and
left mounting surfaces.
within 0.15 mm (0.006")
〈2〉When the scale mounting surface is a casting
surface
Mount the scale using mounting brackets
(1) When the scale mounting surface is a casting
surface and parallelism is not satisfied
Use mounting brackets and adjust so that the
parallelism specified in 〈1〉may be satisfied.
Mounting brackets are only necessary at the left and
right foot areas of the scale. They do not need to
extend the entire length of the scale. However, if it is
not possible to measure the parallelism of the left and
right feet due to the movable length of the mounted
unit, it will be necessary to make longer mounting
brackets.
