1.4 EMC-compliant Installation

For EMC-compliant installation, refer to the operating or design guide and follow the electrical installation instructions.
• Use shielded cables for motor (unshielded cables in metal conduit are acceptable), brake, DC, and control wiring.
• Connect the shield to the enclosures at both ends. If the shield connection points have a voltage potential difference, connect a
low impedance equalizing wire parallel to the shielded cable. Otherwise, break the shield connection on 1 end to prevent
ground current loops.
• Ensure that motor, brake, and DC cables are as short as possible to reduce the interference level from the entire system.
• Provide a minimum 200 mm (7.9 in) separation between mains input, motor cables, and control cables.
• Convey the currents back to the unit using a metal mounting plate. Ensure good electrical contact from the mounting plate
through the mounting screws to the drive chassis.

1.5 Installing the Drive

SHOCK HAZARD
Touching an uncovered motor, mains, or DC connection plug or terminal can result in death or serious injury.
-
All plugs and terminal protection covers for the motor, mains, and DC connections must be installed within the IP20 enclo-
sure to provide an IP20 protection rating. If the plug and terminal covers are not installed, the protection rating is considered
IP00.
Installation location is important. Full output current is available when the following installation conditions are met. For tempera-
tures and altitudes outside this range, consult the Derating section in the design guide.
• Maximum ambient air temperature for high overload operation: 45
low overload, maximum ambient air temperature: 40
• Minimum ambient air temperature: -30
• Altitude < 1000 m (3280 ft) above sea level.
Procedure
1. Identify the frame designation. See
2. Make sure that the operating environment and electrical installation meet the following standards.
- a. Indoor unconditioned/pollution degree 2.
- b. Overvoltage category 3.
3.
Review the wiring diagram. See step 1 in the Illustrations section.
All wiring must comply with local and national regulations regarding cross-section and ambient temperature require-
ments. Loose connections can cause equipment faults or reduced performance. Tighten the terminals according to the
proper torque value shown in step 8.
4. Review the fuse specifications. See step 2 in the Illustrations section.
The drive can be suitable for use on a circuit capable of delivering up to 100 kA short circuit current rating (SCCR) at the
respective drive voltage rating. For mains disconnect switch SCCR ratings, see the design guide.
5. Review the power cable specifications. See step 3 in the Illustrations section.
Use copper wire with a minimum 70
6. Install the drive following the numbered steps in the Illustrations section. Certain illustrations/steps pertain to specific
frame designations and are marked as such. If the illustration or step applies to all variants, the 2nd character in the frame
designation is replaced with an x – for example Fx09 indicates FA09, FB09a, FB09c, FK09a, and FK09c. In instances where
FK09 or FK10 frame designations are used, the illustration/step includes both the standard height (a) and extended
height (c) variants.
- a. Attach the components from the accessory bag to the drive (step 4).
- b. Mount the drive on or against a solid, non-combustible mounting surface such as concrete or metal (step 5). If
configured with the heat sink access panel option, provide clearance for the access panel.
FK09a/FB09a, FK09c/FB09c, and FK10a/FB10a can be free-standing if installed with the optional pedestal kit.
