1.8 Connection Tightening Torques
Make sure to use the right torques when tightening all electrical connections. Too low or too high torque sometimes causes electri-
cal connection problems. To ensure that correct torques are applied, use a torque wrench. Recommended slot screwdriver type is
SZS 0.6x3.5 mm.

1.9 Installing the Drive
1.9.1 Installation Environment
Follow the information in this chapter to select a suitable installation location.
In environments with airborne liquids, particles, or corrosive gases, ensure that the IP/Type rating of the equipment matches the
installation environment. Failure to meet requirements for ambient conditions can reduce the lifetime of the frequency converter.
Ensure that requirements for air humidity, temperature, and altitude are met.
Full output current is available when the following installation conditions are met:
Maximum ambient air temperature: 45 °C (113 °F)
Minimum ambient air temperature: 0 °C (32 °F)
Maximum altitude without derating: 1000 m (3280 ft)
For temperatures and altitudes outside this range, consult the VLT
