Delta Electronics VFD-VL manual

WARNING!

1.DO NOT use Hi-pot test for internal components. The semi-conductor used in AC motor drive easily damage by high-voltage.

2.There are highly sensitive MOS components on the printed circuit boards. These components are especially sensitive to static electricity. To prevent damage to these components, do not touch these components or the circuit boards with metal objects or your bare hands.

3.Only qualified persons are allowed to install, wire and maintain AC motor drives.

CAUTION!

1.Some parameters settings can cause the motor to run immediately after applying power.

2.DO NOT install the AC motor drive in a place subjected to high temperature, direct sunlight, high humidity, excessive vibration, corrosive gases or liquids, or airborne dust or metallic particles.

3.Only use AC motor drives within specification. Failure to comply may result in fire, explosion or electric shock.

4.To prevent personal injury, please keep children and unqualified people away from the equipment.

5.When the motor cable between AC motor drive and motor is too long, the layer insulation of the motor may be damaged. Please use a frequency inverter duty motor or add an AC output reactor to prevent damage to the motor. Refer to appendix B Reactor for details.

6.The rated voltage for AC motor drive must be ≤ 240V (≤ 480V for 460V models) and the mains supply current capacity must be ≤ 5000A RMS (≤10000A RMS for the ≥ 40hp (30kW) models)
