Wiring Procedure
The cable lead-in system of this unit uses flameproof packing. The compatible
cable outer diameter is 10 to 14mm. The following flameproof packing sets
are included with this unit.
• Flameproof packing set for 10 to 12mm outer diameter cable
• Flameproof packing set for 12 to 14mm outer diameter cable
(1) Loosen the setscrew to open the cover.
(2) Insert the cable into the unit as shown in the figure on the right, and con-
nect the cable to the terminal block.
(3) Screw in the cable gland so that the amount of compression corresponds to the cable diameter as specified in the “Cable outer diameter
and amount of packing compression” table below.
(4) Tighten the lock nut.
(5) Secure the cable using the cable clamp.(Tightening torque: 0.6Nm)
(6) Connect the battery cable included with this unit to the battery connector and insert the battery into the battery holder. The cable can be
connected to either battery connector.
Note
• The table below shows the proper amount of packing compression for various cable diameters. The appropriate amount of packing com-
pression varies depending on the cable diameter and the packing inner diameter. Measure the outer diameter of the cable and choose the
most appropriate amount of compression for the cable from the table below. The amount of compression can also be adjusted by the num-
ber of screw rotations. In the table, counting of the number of screw rotations begins when the cable gland contacts the packing.

Handling Precautions
• Keep wiring away from cables connected to a commercial power supply or motor drive power supply that is likely to produce electrical
noise.
• If this unit is used alone, its miswiring protection is effective. However if multiple units are connected through RS-485, miswiring of the
power source may cause device failure. Be sure to check that the wiring is correct before turning the power on.
• For screw terminal connections, use crimp terminals that are the correct size for M3.5 screws.
• For spring screw terminal connections, use wires whose nominal cross-sectional area is 0.25 to 0.75 mm2(24 to 18 AWG), with bootlace
ferrules. Use bootlace ferrules and a crimping tool that comply with the following standards.
Do not insert stripped or soldered ends of stranded wires into the spring terminal block.
Bootlace ferrule: DIN 46228 sect. 4
Crimping tool: DIN 46228 parts 1 and 4

• To connect a wire to the spring terminal block, insert a bootlace ferrule into the hole (push-in system).
• To remove a wire from the spring terminal block, push the button on the block using a flat-head screwdriver (tip size: 0.4×2.5 mm) and
pull out the wire. The standard pushing force on the button and the pushed distance are 20 N and 1.7 mm respectively. If the pushing
force on the button is 40 N or greater, device failure could result.
• For wiring for RS-485, do not connect an external terminating resistor.
• For wiring, follow the wiring diagram.
• Use shielded cables. Use a shielded cable to wire the ground terminal inside the case.
• Use either of the following methods so that there is only one ground connection.
(1) Ground the other end of the shielded cable that is connected to the ground terminal inside the case.
(2) Ground the ground terminal that is outside the case.
The ground connection should have a resistance of 100 Ω or less.
• If the battery included with this unit is not used, the clock data and recorded waveform data will not be backed up while power is not
being supplied. In this case, the unit will have a minor failure status.
• If the battery is not connected to the unit or if the clock is not set, the unit will have a minor failure status.
• If the removed battery is connected to the unit again, the unit may
take time to recognize the battery. Until it is recognized, the unit
will have a minor failure status.
• If there is a risk of power surge caused by lightning, use Azbil
Corporation’s FA SurgeNon surge protector (QN430C series).
Make the wiring between the unit and the SurgeNon as short as
possible.
