Wire Type and Ratings
• All wiring must comply with local and national regulations regarding cross-
section and ambient temperature requirements.
• Power connection wire recommendation: minimum 167°F [75°C] rated copper
wire.
See Chapter 8.1 Electrical Data and Chapter 8.5 Cable Specifications for recom-
mended wire sizes and types.
4.2 EMC-compliant Installation
To obtain an EMC-compliant installation, follow the instructions provided in Chap-
ter 4.3 Grounding, Chapter 4.4 Wiring Schematic, Chapter 4.6 Motor Connection,
and Chapter 4.8 Control Wiring.
4.3 Grounding
For electrical safety
• Ground the adjustable frequency drive in accordance with applicable standards
and directives.
• Use a dedicated ground wire for input power, motor power and control wiring.
• Do not ground one adjustable frequency drive to another in a “daisy chain”
fashion.
• Keep the ground wire connections as short as possible.
• Follow the motor manufacturer wiring requirements.
• Minimum cable cross-section: AWG 7 [10 mm
2
] (or two rated ground wires
terminated separately).
For EMC-compliant installation
• Establish electrical contact between cable shield and adjustable frequency
drive enclosure by using metal cable connectors or by using the clamps
provided on the equipment (see Chapter 4.6 Motor Connection).
• Use high-strand wire to reduce electrical interference.
• Do not use pigtails.
Note:
POTENTIAL EQUALIZATION
Risk of electrical interference, when the ground potential between the adjustable
frequency drive and the system is different. Install equalizing cables between the
system components. Recommended cable cross-section: AWG 6 [16 mm
2
].
LEAKAGE CURRENT HAZARD
Leakage currents exceed 3.5 mA. Failure to ground the adjustable frequency
drive properly could result in death or serious injury.
• Ensure correct grounding of the equipment by a certified electrical installer.
