Safety Instructions
1
When using Shihlin inverters, please follow the installation to ensure the safety of user and others.
The following instructions will be classified and described by icons
:
DANGER
It means dangerous instructions, and incorrect handling may result in death or severe
injury.
CAUTION
It means caution instructions. Incorrect handling may result in injury or property
damage.
It means caution and execution need to be done. Please operate according to the
instructions.
DANGER
Inverters must be used on the location except corrosive gas, water, flammable
gas.
Please operate far from flammable substance or explosives.
Please do not lay the inverter on an intense trembling or shaking occasion.
Do not operate wires soaked under oil or water.
Prohibit touching any part in the inverter when power is ON to avoid electric
shock.
Three-phase power cannot be connected to terminal U/T1, V/T2, W/T3.
The terminal
of the inverter must be correctly grounded.
Do not conduct wiring when the power is ON.
CAUTION
Do not conduct hi-pot test on internal components of the inverter, for
semiconductor is easily damaged by high voltage.
There are CMOS IC components on PCBAs which are especially sensitive to
static electricity. Please do not touch PCBAs before taking anti-static measures.
Even if the motor stops, a charge may still remain in the main circuit terminals of
the inverter with hazardous voltages.
Only qualified persons are allowed to install, wire and maintain the inverter.
After some functions are set, the motor may start immediately once power is ON.
Please choose the safe area to install the inverter, avoiding heat, direct sunlight,
moisture humidity and splashing of droplets.
When wiring between the inverter and motor is too long, it may damage the layer
insulation of the motor. A reactor can be mounted between inverter and motor,
avoiding insulation is damaged.
For the installation power system of rated voltage, it cannot be over 240V for 220
series; it cannot be over 480V for 440 series.
Only qualified personnel familiar with wiring is allowed to perform wiring.
For the installation direction and method, please refer to the regulations.
Make sure to use the temperature in a safe range.
Please follow the installation to use the voltage.
When there are problems in operation, please first unload the motor, after
zero-load operation is OK, and then connect to the machine.
Please confirm whether the inverter power is in line with the motor power.
Before running, please confirm whether the emergency switch can operate
normally.
Power wire, U, V, W wires and signal wire should not be stranded, but separately.
Please turn off the power if it is not used for a long time.
