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-R2, 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-R2 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-R2 to and from the DIN rail
• Installing the N-R2 to the DIN rail
1 Lower the mounting tab on the back of the N-R2.
Check that the mounting tab is placed in the position shown in the
following diagram.
* It can be connected with Keyence’s optional cable OP-27937 (2 m).
Installing the N-R2
■ Surrounding space
• Install the N-R2 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 NR2. As long as the N-R2 is the only
source of heat generation, the N-R2 can
be installed without space on the right
and left sides.
Provide a space of 80 mm or more in front
of the N-R2 to connect the BL head.
2 Install the N-R2 to the DIN rail as shown in the following
diagram.
