General
1
Compliance with category C1 conducted emissions only is achieved.
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 cable within a suitable steel or copper tube is also acceptable - in this case, ensure that metal tube is adequately
grounded.
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 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 cable within a suitable steel or copper tube is also acceptable – in this case, ensure that metal tube is adequately
grounded.
6
The cable shield should be terminated at the motor end using an EMC type gland allowing connection to the motor body through
the largest possible surface area. The shield must also be terminated at the drive end, as close as practically possible to the drive
output terminals. Where drives are mounted in a steel control panel enclosure, the cable screen may be terminated directly to the
control panel backplate using a suitable EMC clamp or gland fitted as close to the drive as possible. The drive earth terminal must
also be connected directly to this point, using a suitable cable which provides low impedance to high frequency currents. For IP55
and IP66 drives, connect the motor cable shield to the gland plate or internal ground clamp.
7
A cable suitable for fixed installation with relevant 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.
