■ Processing the communication cable

1 Remove the sheath of the cable by 70 mm.

2 Cover the bare shield mesh wires and the sheath portion

with a contraction tube of about 40 mm.

3 Make stranded wires from the shield mesh wires and

prepare the required number of wires including the insulated wires. (5 wires are required for the RS-422A and 3 wires are required for the RS-485)

4 Remove the cover of each insulated wire by about 8 mm

from the tip.

5 Perform preliminary soldering on each wire by about 6 mm

from the tip. The external diameter of the preliminarily soldered bare wire must not exceed 2 mm.

Installing the N-R4

■ Surrounding space

• Install the N-R4 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-R4. As long as the N-R4 is the only source of heat generation, the N-R4 can be installed without space on the right and left sides. Provide a space of 80 mm or more in front of the NR4 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-R4, 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-R4 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).
