Amplifier Units
z Designing
Communications Hole
Fiber Connection and Disconnection
The E3X Amplifier Unit has a lock lever. Connect or disconnect the
fibers to or from the E3X 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
lever.
Insertion position
Lock button
The hole on the side of the Amplifier Unit is a communications hole for
preventing mutual interference when Amplifier Units are mounted
side-by-side. The E3X-MC11 Mobile Console (order separately)
cannot be used.
If an excessive amount of light is received via the Sensor, the mutual
interference prevention function may not work. In this case, make the
appropriate adjustments using the sensitivity adjuster.
The mutual interference prevention function will not operate when the
E3X-NA is used side-by-side with E3X-DA-N models.

Note: To maintain the fiber properties, confirm that the lock is released
before removing the fiber.
2. Slide the Amplifier Units together, line up the clips, and press the

Removing Amplifier Units
Slide Amplifier Units away from each other, and remove from the DIN
track one at a time. (Do not attempt to remove Amplifier Units from the
DIN track without separating them first.)
Note: 1. The specifications for ambient temperature will vary according to the
number of Amplifier Units used together. For details, refer to Ratings
and Specifications.
2. Always turn OFF the power supply before mounting or removing
Amplifier Units.
If dust or dirt adhere to the hole for optical communications, it may
prevent normal communications. Be sure to remove any dust or dirt
before using the Units.
