Connection
Do not pull or press the Fiber Units. The Fiber Units have a
withstand force of 1 kg or 3 kg (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.
Do not apply excess force on the Fiber Units.
The Fiber Head could be broken by excessive
vibration. To prevent this, the following is effective:

Mounting
Removal
By pulling back the lock (yellow) on the bottom with a flat blade
screwdriver, the amplifier can be removed with ease.
In the case of 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 6 mm max.
Others
When power is off:
The moment power is turned off, the E3X could output a pulse
signal which could affect the operation of the devices
connected to it. This will happen more often if power is supplied
to the E3X from an external power supply, thus affecting the
connected timer and counter. Use a built-in power supply as
much as possible to avoid this.
If power is supplied to a photoelectric sensor through a cord
that is wired together with other power lines in the same duct,
the cord will be influenced by the power lines and
malfunctioning of the photoelectric sensor or damage could
result. Wire the cord separately or use a sealed cord to supply
power to the photoelectric sensor.
If the case of the cord is extended, use a wire with 0.3 mm
max.. The total length of the cord should be 100 m max.
Power supply:
If a standard switching regulator is used as a power supply, the
frame ground (FG) terminal and the ground (G) terminal must
be grounded, or otherwise the E3X can malfunction, influenced
by the switching noise of the power supply.
The supplied voltage must be within the rated voltage range.
Unregulated full- or half-wave rectifiers must not be used as
power supplies.
Do not use a hammer to hit the amplifier when mounting or the
amplifier will loose watertightness.
