Chapter 2 Installation and Wiring
2.1 Ambient Conditions
Install the AC motor drive in an environment with the following conditions:
Operation Air Temperature: -10 ~ +40°C (14 ~ 104°F) for UL & cUL
-10 ~ +50°C (14 ~ 122°F) without dust cover.
Relative Humidity: <90%, no condensation allowed
Atmosphere pressure: 86 ~ 106 kPa
Installation Site Altitude: <1000m
Vibration: <20Hz: 9.80 m/s

(1G) max
20 ~ 50H: 5.88 m/s
2
(0.6G) max
Storage
Transportation
Temperature: -20°C ~ +60°C (-4°F ~ 140°F)

(0.6G) max
Pollution Degree 2: good for a factory type environment.
CAUTION!
1. Operating, storing or transporting the AC motor drive outside these conditions may cause damage to the
AC motor drive.
2. Failure to observe these precautions may void the warranty!
2.2 Installation
1. Mount the AC motor drive vertically on a flat vertical surface object by screws. Other directions are not
allowed.
2. The AC motor drive will generate heat during operation. Allow sufficient space around the unit for heat
dissipation.
3. The heat sink temperature may rise to 90°C when running. The material on which the AC motor drive is
mounted must be noncombustible and be able to withstand this high temperature.
4. When AC motor drive is installed in a confined space (e.g. cabinet), the surrounding temperature must be
within 10 ~ 40°C with good ventilation. DO NOT install the AC motor drive in a space with bad ventilation.
