1.1.2 Safety Precautions
WARNING
requirements may result in fire or serious personal injury or even death.
ATTENTION
requirements may damage to inverter or equipment system.
Notice: Based on different situations, "CAUTION" issue may also cause severe
consequences. Please comply with above two grade issues, which are both vital to our
individual safety.

Make sure the power is off before wiring.
 Within 10 minutes after turning off AC power supply, there's high voltage still inside
inverter, which is extremely dangerous. DO NOT touch the electric circuit or any
spare part inside.

When inverter is under working, DO NOT inspect the spare part or signal on electric
circuit.

DO NOT dismount or change the inside wiring, electric circuit or spare part by
yourself.

DO NOT operate inverter with a wet had in case of electric shock.

Ierter ground terminals must be correctly grounded.

It is prohibited to reassemble or change control board and spare parts, otherwise
there will be dangers such as electric shock, explosion, etc.

NEVER open inverter cover or touch the spare parts on circuit board when inverter is
power-on. There is high voltage on these parts. Beware of electric shock which
results death!!!

DO NOT carry out puncture test on the accessories inside the inverter, for they are prone
to be damaged by high voltage.

NEVER connect the output terminal U.V.W to AC power supply.

When power is on or has been cut off just for a short while, inverter and braking resistor
stay in high temperature, DO NOT touch them in case of being scalded.

The voltage on each terminal must comply with the indication on manual, to prevent
crack and damage.

Inverter main electric board CMOS, IC are prone to be influenced and damaged by static
electricity.

Only qualified specialized persons are permitted to install, debug and maintain the
inverters.

Dump the inverters as industrial waste. Burning is not allowed.

After the inverter being kept aside for long time, inspection and commissioning are
required before using.
Inverters can be set for high speed running easily. Please check whether the motor and
