E3X-NH
When Side-Mounting
Insert the fiber into the Amplifier up to the insertion mark. Proper
fiber performance will not be achieved unless the fiber is inserted
all the way to the insertion mark. (This method is applicable to
standard, 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
distance will be reduced. Always use an unused hole.
Use either one of the two holes on the right (refer to the following
figure) to cut a thin fiber as follows:

When side-mounting:
Attach the mounting bracket on the Amplifier first, and secure
the amplifier with M3 screws and washers. The diameter of
the washers should be a maximum of 6 mm.

Note:
Connection
Do not pull or press the Fiber Units. The Fiber Units have a
withstand 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).
Do not apply excess force on the Fiber Units.
The Fiber Head could be break by excessive vibration. To
prevent this, the following is effective:
Turning the Power ON
When the power is turned ON, the operation indicator will be ON
momentarily. Note that this will not have an effect on performance
since no control output will be generated.
When the power is turned ON, the operation indicator will be ON
momentarily. Note that this will not have an effect on performance
since no control output will be generated.
Perform two-point teaching if two to three Fiber Units are closely
mounted together, at which time supply power only to the Unit in
teaching operation in turn or block the emitters of the Fiber Units
not in teaching operation.
