Installation Guide
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 ambient temperature: 45 ºC (113 ºF) average over 24 hours and 50 ºC (122 ºF) for 1 hour.

Minimum ambient temperature: 0 ºC (32 ºF).

Altitude < 1000 m (3280 ft) above sea level.

1. Identify the enclosure size. See Illustration 1.
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® PROFINET MCA 120 documentation.
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 requirements.
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 ºC (158 ºF) rating. For aluminum wire, see the product-specific design guide.
7. Install the drive following the numbered steps in the Illustrations section. Certain illustrations/steps pertain to specific enclosure
sizes and are marked as such.
a. Attach accessory bag components to the drive. See step 5 in the Illustrations section.
b. Mount the drive on or against a solid, non-combustible mounting surface such as concrete or metal. Ensure proper cooling
by providing minimum clearance above and below the drive. See step 6 in the Illustrations section.
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. See step 7 in the Illustrations section.
d. Install the control wiring. See step 8 in the Illustrations section.
e.
Install the motor, mains, and ground wiring. See step 9 in the Illustrations section.
f.
Route the control cables towards the left side of the drive.
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.
