VLT Frequency Converters, 0.25–90 kW
Installation Guide
Minimum ambient temperature: 0 ºC (32 ºF).

Altitude < 1000 m (3280 ft) above sea level.

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® PROFINET MCA 120 documentation.
3.
Make sure that the operating environment and electrical installation meet the following requirements.
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 and (Moeller) circuit breaker specifications. In certain instances, a specific enclosure size is shown in
parentheses, indicating that the item applies only to that specific enclosure size. See step 3 in the Illustrations section.
The drive may 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.
c. Create 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 ground wiring, then the motor wiring, and then the mains wiring. See step 9 in the Illustrationssection.
f. Route the control cables to the left side of all drives except for the B3. For B3 drives, route the control cables to the right
side.
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.
Fire/Emergency Mode
1.8
When running in fire/emergency mode, the frequency converter can be programmed to sacrifice itself so the applications (for example,
ventilation or water pumps) continue to operate as long as possible.
