Installing The Drive - Danfoss iC7 Installation Manual

iC7-Automation Frequency Converters
Installation Guide
• Convey the currents back to the unit using an EMC plate. Ensure good electrical contact from the EMC plate through the mount-
ing screws to the drive chassis.
• Parts identified with ( ! ) must be installed. See step 4 in the Illustrations section.

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.
The installation location is important.
Full output current is available when the following installation conditions are met. For temperatures and altitudes outside this
range, consult the Derating section in the design guide.
• Maximum surrounding air temperature: 45
• Minimum surrounding air temperature: 0
• 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
480/600 V. For circuit breaker and 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
sures. For aluminum wire, see the design guide.
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.
a.
- Attach accessory bag components 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). En-
sure proper cooling by providing minimum clearance above and below the drive.
- c. For frames FK06–FK08, drill cable openings in the cable entry plate and install the cable glands (step 6).
- d. Install the control wiring (step 7).
- e. Install the motor, mains, and ground wiring (step 8).
- f. Route the control cables (step 9)
7. Securely fasten the cover to the drive.
8. Perform initial drive and motor setup. Consult the application guide.
