Delta Electronics VFD-VL manual Remove Front Cover, 15HP/5.5-11kWframe C & 20-30HP/15-22kWframe D

Chapter 1 Introduction

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!

3.Mount the AC motor drive vertically on a flat vertical surface object by screws. Other directions are not allowed.

4.The AC motor drive will generate heat during operation. Allow sufficient space around the unit for heat dissipation.

5.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.

6.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.

7.Prevent fiber particles, scraps of paper, saw dust, metal particles, etc. from adhering to the heatsink.

8.When installing multiple AC more drives in the same cabinet, they should be adjacent in a row with enough space in-between. When installing one AC motor drive below another one, use a metal separation between the AC motor drives to prevent mutual heating.
