8-4 Operation, Storage and Transportation Environments
DO NOT expose the AC motor drive to a poor environment, such as one with dust, direct sunlight, corrosive or
inflammable gases, humidity, liquids or excessive vibration. The salt in the air must be less than 0.01 mg/cm

Altitude
Operation
If the AC motor drive is installed at an altitude of 0–1000 m, follow
normal operation restrictions. For altitudes of 1000–3000 m,
decrease the drive’s rated current by 1% or lower the temperature
by 0.5°C for every 100 m increase in altitude. The maximum
altitude for corner grounding is 3000 m. If installing at an altitude
higher than 3000 m is required, contact Delta for more information.

: TN system: The neutral point of the power system connects directly to the ground. The exposed
metal components connect to the ground through the protective grounding conductor.
2
: Single-phase models use a single-phase three-wire power system.
