I
PLEASE READ PRIOR TO INSTALLATION FOR SAFETY.
D ANGER

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.
C AU TION

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.

If the AC motor drive is stored in no charge condition for more than 3 months, the
ambient temperature should not be higher than 30 °C. Storage longer than one year is
not recommended, it could result in the degradation of the electrolytic capacitors.

The performance of electrolytic capacitor will degrade if it is not charged for a long time.
It is recommended to charge the drive which is stored in no charge condition every 2
years for 3~4 hours. NOTE: When the AC motor drive is in charge condition, it should
supply 70~80% of rated voltage by using variable AC power (ex. AC autotransformer) for
30 minutes first (don’t operate it), and then provide rated voltage for 1 hour (still don’t
operate it), to make electrolytic capacitor revive and start operating. Do not provide rated
voltage to operate the drive directly.

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.
4. It is strictly forbidden to use steamed smoking sterilization. The warranty does
not covered VFD damaged by steamed smoking sterilization.

Type of electrical supply system (3WYE) to which the drive shall be connected.
