Connection of mains filter for power line
To prevent the noise generated from the driver being transferred to the outside through
the power supply transformer, connect a mains filter to the AC input line of the power
supply transformer.
Use FN250-12/07 by Schaffner Electronik AG, 10ESK1 by CORCOM, ZAG2210-11S by
TDK or their equivalent as the mains filter.
Install the mains filter as close as possible to the driver. Use cable clamps or similar tools
to fix the input cable and output cable. The input cables and output cables to be firmly
ensured that they will not be separated from the surface of the enclosure. Connect
the grounding terminal of the mains filter to the grounding point in the shorter distance.
Do not connect the AC input cable (AWG18: 0.75mm
2
or more) and mains filter output
cables in parallel to each other. Otherwise, the noise in the enclosure may be connected
directly with the power cable through the floating capacity. This may result in the effects
reduced of the mains filter.

Grounding method
To ensure that potential difference will not occur, connect the driver, motor and mains
filter to the grounding point in the shorter distance by the use of a larger grounding cable.
Use a large uniform conductive surface for the grounding point.

Connection of signal cable
High quality braided-screen cable of AWG24 (0.2mm
2
) or more should be used for signal
cabling, and connect it to a controller in the shorter distance.
For some products, such braided-screen cable is available as an option. Please inquire
at your nearest Oriental Motor sales office.
To earth the braided-screen, use such clamps as metallic cable clamps which can be in
contact with the circumference of the braided-screen cable. Cable clamps on the
braided-screen cable should be installed as close to the cable end as possible as per
illustrated. On of the braided-screen cable, as illustrated. Connect the earth wire to the
adequate grounding point.
