Optional Input Choke; Emc Compliant Installation - ABB EC Titanium Series Manual

4.4 Optional Input Choke

An optional Input Choke is recommended to be installed in the supply line for drives where any of the following conditions
occur. In all other installations, an input choke is recommended to ensure protection of the drive against power supply faults.
• The incoming supply impedance is low or the fault level / short circuit current is high
• The supply is prone to dips or brown outs
• An imbalance exists on the supply (3 phase drives)

1. 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.
2. 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.
3. A cable suitable for fixed installation with relevant mains voltage. A shielded type cable is not necessary.
4. A shielded cable with low impedance shield. Twisted pair cable is recommended for analog signals.
5. 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.
6. Compliance with category C1 conducted emissions only are achieved. For compliance with category C1 radiated
emissions, additional measures may be required, contact your Sales Partner for further assistance.
7. Permissible cable length with additional external EMC filter.
