Compliance with category C1 conducted emissions only is achieved. For compliance with category C1 radiated emissions,
additional measures may be required, contact your Sales Partner for further assistance.
Supply Cable
2
A screened (shielded) cable suitable for fixed installation with the relevant mains voltage in use. Braided or twisted type screened
cable where the screen covers at least 85% of the cable surface area, designed with low impedance to HF signals. Installation of
a standard.
3
A cable suitable for fixed installation with relevant mains voltage with a concentric protection wire. Installation of a standard cable
within a suitable steel or copper tube is also acceptable.
4
A cable suitable for fixed installation with relevant mains voltage. A shielded type cable is not necessary.
Motor Cable
5
A screened (shielded) cable suitable for fixed installation with the relevant mains voltage in use. Braided or twisted type screened
cable where the screen covers at least 85% of the cable surface area, designed with low impedance to HF signals. Installation of
a standard.
6
The cable screen should be terminated at the motor end using an EMC type gland allowing connection to the motor body
through the largest possible surface area. Where drives are mounted in a steel control panel enclosure, the cable screen may be
terminated directly to the control panel using a suitable EMC clamp or gland, as close to the drive as possible. For IP66 drives,
connect the motor cable screen to the internal ground clamp.
7
A cable suitable for fixed installation with relevant mains voltage with a concentric protection wire. Installation of a standard cable
within a suitable steel or copper tube is also acceptable.
Control Cable
8
A shielded cable with low impedance shield. Twisted pair cable is recommended for analog signals.

4.3.4. Wiring Precautions
Connect the Optidrive according to section
, ensuring that motor terminal box connections are correct.
There are two connections in general: Star and Delta. It is essential to ensure that the motor is connected in accordance with the
voltage at which it will be operated. For more information, refer to section
4.6. Drive and Motor Connection
.
It is recommended that the power cabling should be 4-core PVC-insulated screened cable, laid in accordance with local industrial
regulations and codes of practice.
