Fiber Connection and Disconnection
The E3X-NA Amplifier Unit has a lock button. Connect or discon-
nect the fibers to or from the E3X-NA Amplifier Unit using the
following procedures:
1.
Connection
Open the protective cover, insert the fibers according to the
fiber insertion marks on the side of the Amplifier Unit, and
lower the lock button.

Note:
To maintain the fiber properties, confirm that the lock is re-
leased before removing the fiber.
3. Precautions for Fiber Connection/Disconnection
Be sure to lock or unlock the lock button within an ambient
temperature range between −10°C and 40°C.
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.
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
distance will be reduced. Always use an unused hole.
Cut a thin fiber as follows:
1. An attachment is temporarily fitted to a thin fiber before ship-
ment.

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