PLEASE READ PRIOR TO INSTALLATION FOR SAFETY.

DANGE

 AC input power must be disconnected before any wiring to the AC motor drive

is made.

 Even if the power has been turned off, a charge may still remain in the DC-link

capacitors with hazardous voltages before the POWER LED is OFF. Please do

not touch the internal circuit and components.

 There are highly sensitive MOS components on the printed circuit boards.

These components are especially sensitive to static electricity. Please do not

touch these components or the circuit boards before taking anti-static

measures. Never reassemble internal components or wiring.

 Ground the AC motor drive using the ground terminal. The grounding method

must comply with the laws of the country where the AC motor drive is to be

installed.

 DO NOT install the AC motor drive in a place subjected to high temperature,

direct sunlight and inflammables.

CAUTION

 Never connect the AC motor drive output terminals U/T1, V/T2 and W/T3

directly to the AC mains circuit power supply.

 Only qualified persons are allowed to install, wire and maintain the AC motor

drives.

 Even if the 3-phase AC motor is stop, a charge may still remain in the main

circuit terminals of the AC motor drive with hazardous voltages.

 The performance of electrolytic capacitor will degrade if it is not charged for a

long time. It is recommended to charge the driver which is stored in no charge

condition every 2 years for 3~4 hours.

 Please use adjustable AC power source (ex: AC autotransformer) to charge the

driver gradually to rated voltage, and should not charge it directly with rated

voltage.

 Pay attention to the following when transporting and installing this package

(including wooden crate, wood stave and carton box)

1. If you need to sterilize, deworm the wooden crate or carton box, please

do not use steamed smoking sterilization or you will damage the VFD.

2. Please use other ways to sterilize or deworm.

3. You may use high temperature to sterilize or deworm. Leave the

packaging materials in an environment of over 56℃ for 30 minutes.

 It is strictly forbidden to use steamed smoking sterilization. The warranty does

not covered VFD damaged by steamed smoking sterilization.
