  2. 2. DZB Series Preface Preface Thank you for choosing DZB 200M&J Series AC Motor D rives. This manual will be helpful in the installation, parameter setting, t rou bleshooting, and daily maintenance of the AC motor drives. To guaran tee safe operation of the equipment,read the following safety guidelines before connecting power to the AC drives. Keep this operating manual han dy and distribute to all users for reference. Attention: ◆ Al ways read this manual thoroughl y before using DZB series A C Motor Drives. ◆ Do not connec t or disconnect wi res and connectors whi le power is applied to the ci rcui t. ◆AC input power must be disconnect ed before any maintenance. ◆The re are hi ghly sensitive components on the printed ci rcui t boards. These components are especially sensit ive t o ESD (electrostatic discharge). To avoi d damage to th e dr ive ,do not touch component s or the ci rcuit boards until stat ic control precautions have been ta ken. ◆To avoid personal i njury, do not remove the cover of the AC motor dri ve until al l of the digi tal keypad "DISPLAY LED" lamps are off. The DC-link capacitor remains charged with a hazardous voltage even after input power is removed. ◆ Never connect the main circuit output terminals U, V, and W directly to the AC main circuit power suppl y as this will damage the drive . ◆ Grounding the Inverter by c onn ecting the Earth Ground to the drive ground terminal.
