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 ~ +50°C (14 ~ 122°F)

 

 

-10 ~ +40°C (14 ~ 104°F) for side-by-side

 

 

mounting

 

Relative Humidity:

<90%, no condensation allowed

 

Atmosphere pressure:

86 ~ 106 kPa

 

Installation Site Altitude:

<1000m

 

Vibration:

<20Hz: 9.80 m/s2 (1G) max

 

 

20 ~ 50Hz: 5.88 m/s2 (0.6G) max

Storage

Temperature:

-20°C ~ +60°C (-4°F ~ 140°F)

Transportation

Relative Humidity:

<90%, no condensation allowed

 

Atmosphere pressure:

86 ~ 106 kPa

 

Vibration:

<20Hz: 9.80 m/s2 (1G) max

 

 

20 ~ 50Hz: 5.88 m/s2 (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 by using bolts or 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 the 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.
