4-3．DC mode
1. Selection of bar length
・Select the length applicable to work size base on static charge elimination area and static charge
elimination characteristics.
2. Installation of body
・Keep the distance between the ionizer and charged objects within 50 to 2000mm. Although the ionizer
can be mounted outside of this range, it may not operate properly depending on the operating conditions.
Therefore, be sure to check if the ionizer will operate properly.
3. Installation of the sensor
・[Plus ion discharge] or [minus ion discharge] can be selected.
Ion polarity Switch setting
Plus ion discharge 8
Minus ion discharge 9
4. Wiring of the power supply cable
・Connect dedicated power supply cables.

○ ： Wires that are minimum required to operate the ionizer.
△ ： Wires that are required to use the functions.
－ ： Wires that are not necessary with the sensing DC mode. These wires should not be short-circuited with other
cables.
5. Air piping
・When the piping is only connected to one port, the other unused port should be plugged with the M-5P
that is packaged together with the ionizer.
