KEYENCE N-L1 - Manual (Page 3)

3 E N-L1-IM
• Wiring IN1 and IN2
• Wiring OUT1 to 4
■ Wiring the Ethernet port
Use a “straight cable” to connect the N-L1 to the hub; use a “crossover
cable” to connect it to the personal computer directly.
* Use a cable of category 5 or higher. (Both STP and UTP can be used)
* The extended length must not exceed 100 m.
■ Surrounding space
• Install the N-L1 vertically.
When the installation direction changes,
provide adequate surrounding space so
that heat does not build up.
• For ventilation, maintain a space of 50mm
or more from the top and bottom of the N-
L1. As long as the N-L1 is the only source
of heat generation, the N-L1 can be
installed without space on the right and
left sides.
Provide a space of 80 mm or more in front
of the N-L1 to connect the BL head.
50 mm or more on the top and bottom; no space is required on the
right and left sides
■ Installation precautions
• When installing the N-L1, do not block the ventilation slots on the
top and bottom of the unit. Otherwise, heat builds up inside the
unit, causing product failure.
• If the temperature of the N-L1 will foreseeable exceed the upper
limit of the operating temperature (50
°C), take the appropriate
measures such as performing forced air cooling or ensuring
proper ventilation so that the temperature does not exceed the
upper limit of the normal operating temperature (50
°C).
■ Installing and removing the N-L1 to and from the DIN
rail
• Installing the N-L1 to the DIN rail
1
Lower the mounting tab on the back of the N-L1.
Check that the mounting tab is placed in the position shown in the
following diagram.
2
Install the N-L1 to the DIN rail as shown in the following
diagram.

Note
• For connection, use stranded copper wire having a
gage of AWG16 to 26 and temperature rating of 60 °C
or higher.
• The tightening torque is 0.19 N·m (1.7 lbf·in).
CAUTION
The N-L1 does not support PoE (Power over Ethernet).
Be sure to supply 24V DC power to the power terminal.
