Precautions
Be sure to heed the following precautions to fully utilize the capabilities of the E3X-NH/NHB.
General
Do not impose any voltage exceeding the rated voltage on the E3X-
NH/NHB. Do not impose 100 VAC or more on models that operate
with DC. In both cases, the E3X-NH/NHB may be damaged.
Do not short-circuit the load connected to the E3X-NH/NHB, other-
wise the E3X-NH/NHB may be damaged.
When supplying power to the E3X-NH/NHB, make sure that the po-
larity of the power is correct, otherwise the E3X-NH/NHB may be
damaged.
The load must be connected to the E3X-NH/NHB in operation,
otherwise the E3X-NH/NHB may be damaged.

Tightening Force
The tightening force applied to the Fiber Unit should be as follows:
Screw-mounting Model
Spring mounting clip
Toothed washers
Fiber Connection and Disconnection
The E3X-NH/NHB Amplifier has a lock button. Connect or discon-
nect the fibers to or from the E3X-NH/NHB Amplifier using the fol-
lowing procedures:

Fiber insertion mark
Fiber
Remove the protective cover, insert the fiber into the Amplifier, and
lower the lock button until a click is heard.
After cutting the fiber using the E39-F4 Fiber Cutter, put an insertion
mark on the fiber as a guide for correct insertion into the Amplifier,
and then insert the fiber up to this mark.
2. Disconnection
Remove the protective cover and raise the lock lever to pull off the
fiber. (Before removing the fiber, be sure to confirm that the lock is
released so as to maintain the fiber properties.)
Protective cover

3. The fiber must be locked or released in a temperature range of
–10°C to 40°C.
