Connecting Cables
When you have finished with installation, connect the earth lead, the connection cable for the Static
Elimination Blower Unit and the power supply.
■ Connecting the earth lead
Connect the accessory earth lead to the earth connection terminal on the side panel of the Controller
Unit, to conduct grounding.
Alternatively, you can connect the earth lead to the input terminal section on the front panel of
the Controller Unit.
(Refer to
"Controller Unit (I/O Terminal Section)" on page 3)
To prevent electric shock and to ensure accurate static elimination, be sure to
connect a Class D earth.
■ Connecting the cable
Connect the connection cable of the Controller Unit to the input terminal [IN] of the Static Elimination
Blower Unit.
Turn off the power before connecting the connection cable.
When installing the Controller Unit separately from the Static Elimination Blower Unit, use the optional
extension cable (SJ-C2J, SJ-C5J and SJ-C10J).
