3-2. Wiring
·
Wire power cables according to the connection circuit and wiring chart.
3-2-1. Ground the ground terminal
·
Make sure to ground the ground
terminal (F.G.) with a ground resistance of 100Ω or less.
·
The ground terminal (F.G.) is used as a reference electric potential for static neutralization. If the F.G. cable
is not grounded, an optimal offset voltage (ion balance) cannot be obtained, and it may damage the ionizer
and power supply.
3-2-2. Connection Circuit
·
Do not apply excess stress to the mounting part of the controller connector.
·
When the power supply cable is bent, maintain the minimum bend radius.
[Minimum bend radius]
: 40 mm
·
Connect the lead wires according to the wiring diagram.
·
Unused wires should be cut short, or insulated using insulation tape.
·
To satisfy the current capacity, make sure to wire 2 brown cables in which a voltage of 24 VDC is supplied
and 2 blue cables in which 0V is connected.
1)Wiring of IZTC40
When the product is used in DC mode, make sure to ground the F.G. cable (green) and DC(-) cable (blue)
of the input power supply with a resistance of 100 ohms or less. Without grounding the DC(-) cable, the
ionizers and/or power supply may be damaged.
