5. Wiring
Warning
Turn the power supply to the instrument off before wiring.
Working or touching the terminal with the power switched on may result in severe injury
or death due to Electric Shock.

Do not leave bits of wire in the instrument, because they could cause fire, malfunction or trouble.
Insert the connecting cable into the designated connector securely to prevent malfunction.
Connect the wire for AC power source with its designated terminal as described in this instruction
manual.
The IF-400 will be damaged if the AC power source wire is connected to an incorrect terminal.
Tighten the terminal screw with the specified torque.
If excessive force is applied to the screw when tightening, the screw or case may be damaged.
When using a 24V DC for the power source, do not confuse polarity.
This unit does not have a built-in power switch, circuit breaker or fuse. Therefore, it is necessary to
install them in the circuit near the unit externally.
