- Current and voltage wave: power voltage wave closes to sine.
- Without the gas, smoke, dust, defilement, other explosive and corrosive matters which can seriously effect the insulation of voltage regulator in the installation field.
- Without badly vibration and wallow in the installation field.
- Used indoors, parallel connection is not allowed.

USE AND MAINTENANCE
- During the normal operation,the regulator should be checked regularly by charcoal brush and make sure that the brush and contact parts won’t be more thanthe wide of two wires.
- Check the insulation resistance regularly(the relative humidity is 95%, tested with 500 meter),the insulation resistance between coil and base shouldn’t be less than 2 mm.
- For three-phase regulator, please check and adjust the brush regularly.
- Please connect the ground line to regulator case. After operation, turn the hand wheel pointer to “zero”place and cut off the power.
