Installation
Tightening Force
The tightening force applied to the Fiber Unit should be as follows:
Use a proper-sized wrench.
Cutting Fiber
• Insert a fiber into the Fiber Cutter and determine the length of the fiber to be
cut.
• Press down the Fiber Cutter in a single stroke to cut the fiber.
• Cut a thin fiber as follows:
Connection
• Do not pull or press the fiber units. The fiber units withstand tensile or compres-
sion force of 9.8 N or 29.4 N maximum.
• Do not bend the fiber unit beyond the permissable bending radius given under
Ordering Information.
• Do not bend the edge of the fiber units (excluding the E32-T#R and E32-D#R).
• Do not apply excess force on the fiber units.
• The fiber head may break due to excessive vibration. A one turn loop may re-
duce the effect of vibrations:

Insertion direction
• The bending radius of the stainless steel tube should be as large as possible.
The smaller the bending radius becomes, the shorter the sensing distance will
be.
• Insert the tip of the stain-
less steel tube to the
sleeve bender and bend
the stainless steel tube
slowly along the curve of
the sleeve bender (refer
to the figure).
