Installation and Wiring
■Precaution at wiring to HF-TM2
•COM and BC are common terminals for input and output signals, and they are insulated
from one another.
Do not make these common terminals shorted or grounded.
•Do not make them grounded via an external device.
•Separate the wiring to HF-TM2 from that of the main circuit line (power line) or relay
control circuit. If it is unavoidable to do so, make them positioned at right angles to each
other. Otherwise, the inverter may malfunction.
•Although the control circuit terminal block has two lines, you can easily perform wiring
by starting from the lower terminals. Make setting to perform wiring from the lower area.
•When wiring between analog inputs, make sure to check that they are at the desired input
(voltage or current).
•Input of erroneous voltage or current caused by input of a value outside the specification
range (using P24 terminal (24V) instead of ＋V terminal (10V)), incorrect wiring (wires
are installed in reverse orientation and input of voltage/current is reversed, short circuit
occurs between ＋V and COM, wiring of a knob causes short circuit between ＋V and
COM at 0Ω, etc.) may cause failure.
•For wiring to the control circuit terminal block, use twisted shield wires (Recommended
diameter is 0.75mm2), and connect the shield films to each common terminal.
Recommended tightening torque is 0.5 to 0.7 N·m (for M3 screw terminal) or 0.22 to
0.25 N·m (for spring clamp terminal).
•The wiring length to HF-TM2 shall be within 20m. If the connecting wire exceeds 20m,
you may not be able to get sufficient characteristics due to effects of voltage drop.
If it is unavoidable to set the length to more than 20m, use an insulation signal converter
or etc., and check that there is no problem with operation.
•After wiring, lightly pull the wires to check that wires are securely connected.
•For output terminals and relay output terminals, install a diode for preventing
counter-electromotive force.
Otherwise, counter-electromotive force is applied, which may cause failure.
