moisture in the conduit increases the likelihood of VFD faults or warnings. Proper installation is required to make sure there
is no intrusion of water/moisture.

•
Power cable types: Use only copper conductors.
•
Current rating: max. load current.
•
Voltage rating (minimum): 600 V AC cable is accepted for up to 500 V AC, 750 VAC cable is accepted for up to 600
V AC, 1000 V AC cable is accepted for up to 690 V AC.
•
Temperature rating: Use 75 °C conductors minimum, except for drives with a voltage rating of 575 Vac (-6) with
ambient temperature above 40 °C, use 90 °C conductors. Insulation temperature can be higher as long as the
ampacity is based on 75 °C conductors.
•
Size: Refer to
Ratings, fuses and typical power cable sizes
disconnect switch option (F254)
•
Select the control cables. Use double-shielded twisted-pair cable for analog signals. Use double-shielded or single-
shielded cable for the digital, relay and I/O signals. Do not run 24 V and 115/230 V signals in the same cable.
•
Protect the drive and input power cable with the correct fuses. Refer to
4. Examine the installation site
Examine the site where you will install the drive. Make sure that:
•
Site is dry and clean during the installation. Drive is not watertight until installation is complete.
•
The installation site is sufficiently ventilated or cooled to remove heat from the drive.
•
The ambient conditions meet the requirements. Refer to
•
Outdoor installations: protect the drive from direct sunlight to prevent overheating. Drive is UV resistant.
•
The installation surface is as close to vertical as possible and strong enough to support the weight of the drive. Refer to
Weights and free space requirements
•
The installation surface, floor and materials near the drive are not flammable.
•
There is sufficient free space around the drive for cooling, maintenance and operation. For the minimum free space
requirements, refer to
Weights and free space requirements
•
There are no sources of strong magnetic fields such as high-current single-core conductors or contactor coils near the
drive. A strong magnetic field can cause interference or inaccuracy in the operation of the drive.
5. Install the drive on the wall
Select fasteners that comply with local requirements applicable to wall surface materials, drive weight and application.
Prepare the installation site
1.
Make marks with the help of the mounting template. Remove the mounting template before you install the drive on the
wall.
2.
Drill the holes and put anchors or plugs into the holes.
3.
Install the screws. Leave a gap between the screw head and mounting surface.
