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).
