If the portion from the tip to the insertion mark of the fibers are not
inserted into the Amplifier Unit, the sensing distance will be re-
duced.

Use either one of the two holes on the right (refer to the following
figure) to cut a thin fiber as follows:
1. An attachment is temporarily fitted to a thin fiber before
shipment.

2. Secure the attachment after adjusting the position of it in the
direction indicated by the arrow.
3. Insert the fiber into the E39-F4 to cut.

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.
An insertion mark can be placed on the fiber to serve as a reference
when inserting the fiber into the Amplifier. Use the following proce-
dure.
Confirm through the Cutter hole that the fiber is inserted beyond the
insertion mark hole so that the insertion mark is properly indicated,
and then press firmly down on the Cutter.

Connection
Do not pull or press the Fiber Units. The Fiber Units have a with-
stand force of 9.8 N (1 kgf) or 29.4 N (3 kgf) (pay utmost attention
because the fibers are thin).
Do not bend the Fiber Units beyond the permissible bending radius.
Do not bend the edge of the Fiber Units (excluding the E32-TjR
and E32-DjR).

Fiber Unit
Insert the fiber into the Amplifier up to the insertion mark. Proper fi-
ber performance will not be achieved unless the fiber is inserted all
the way to the insertion mark. (This method is applicable to stan-
dard, 2.2-mm-diameter fibers only.)

The cutting holes cannot be used twice. If the same hole is used
twice, the cutting face of the fiber will be rough and the sensing dis-
tance will be reduced. Always use an unused hole.
