Installing The Drive - Danfoss VLT D1h Guia De Instalacion

VLT® Frequency Converters, 90–400 kW
Installation Guide
• If the shield connection points have a voltage potential difference, connect a low impedance equalizing wire parallel to the
shielded cable.
• When using relays, control cables, a signal interface, fieldbus, or brake, connect the shield to the enclosure at both ends. If the
ground path has high impedance, is noisy, or is carrying current, break the shield connection on 1 end to avoid ground current
loops.

1.8 Installing the Drive

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 sections in the product-specific design guide.
• Maximum surrounding air temperature: 45
• Minimum surrounding air temperature: 0
• Altitude < 1000 m (3280 ft) above sea level.
Procedure
1.
Identify the enclosure size. See
2. Identify any options that need extra wiring and setup by using the type code. See step 1 in the Illustrations section.
Scanning the QR code on the cover opens the documentation search page. Use the option number to search for related
documentation. For example, use MCA 120 to search for VLT
3.
Make sure that the operating environment and electrical installation meet the following standards.
- a. Indoor unconditioned/pollution degree 2.
- b. Overvoltage category 3.
4. Review the wiring diagram. See step 2 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 9 in the Illustrations section.
5. Review the fuse specifications. See step 3 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 product-specific design guide.
6. Review the power cable specifications. See step 4 in the Illustrations section.
Use copper wire with a minimum 70
7. Install the drive following the numbered steps in the Illustrations section. Certain illustrations/steps pertain to specific en-
closure sizes and are marked as such.
- a. Attach accessory bag components to the drive (step 5).
- b. Mount the drive on or against a solid, non-combustible mounting surface such as concrete or metal (step 6). En-
sure proper cooling by providing minimum clearance above and below the drive.
D3h–D4h are wall mounted, D1h–D2h and D5h–D6h are wall or floor mounted, and D7h–D8h are floor mounted.
- c. Create cable openings in the cable entry plate (step 7).
- d. Install the control wiring (step 8).
- e. Install the motor, mains, and ground wiring (step 9).
- f. Route the control cables (step 10)
8.
Securely fasten the cover to the drive.
9.
Perform initial drive and motor setup. Consult the product-specific programming guide.
Functional safety options require extra wiring and parameter configuration. See the specific functional safety operating
guide, such as the Safe Torque Off Operating Guide, for more information on installing the safety option.
