WARNING!
Never connect the output terminals U/T1, V/T2, and W/T3 of
brushless DC motor drive directly to the AC mains circuit power
supply.
DO NOT use Hi-pot test for internal components. The semi-
conductor used in brushless DC motor drive easily damage by
high-voltage.
A charge may still remain in the DC-link capacitors with hazardous
voltages, even if the power has been turned off. To prevent
personal injury, please ensure that power has turned off before
opening the brushless DC motor drive and wait for the capacitors
to discharge to safe voltage levels.
Only qualified persons are allowed to install, wire and maintain
brushless DC motor drives.
Some parameters settings can cause the motor to run
immediately after applying power.
CAUTION!
DO NOT install the brushless DC motor drive in a place subjected to high temperature, direct
sunlight, high humidity or liquids.
Only use brushless DC motor drives within specification. Failure to comply may result in fire,
explosion or electric shock.
When the motor cable between brushless DC motor drive and motor is too long, the layer
insulation of the motor may be damaged. Please use a specific brushless DC motor for the
brushless DC motor drive or add a reactor to prevent damage to the motor. Refer to appendix
B Reactor for details.
The rated voltage for brushless DC motor drive must be
≤ 240V (≤ 120V for 115V models and ≤
480V for 460V models).
