Use Stage Safety Grade Precautions
Before
Installation
²Do not install the product if the package is with water,
or component is missing or broken;
²Do not install the product if the label on the package is
not identical to that on the VFD.
²Be careful of carrying or transportation. Risk of devices
damage;
²Do not use damaged product or the VFDs missing
component .Risk of injury;
²Do not touch the parts of control system with bare
hands. Risk of ESD hazard.
²Installation base shall be metal or other non-flammable
material. Risk of fire;
²Do not install VFD in an environment containing
explosive gases, otherwise there is danger of explosion;
²Do not unscrew the fixing bolts, especially the bolts with
red mark.
Installation
CAUTION
DANGER
DANGER
²Do not leave cable strips or screws in the VFD. Risk of
VFD damage;
²Install the product at the place with less vibration and
no direct sunlight;
²Consider the installation space for cooling purpose
when two or more VFDs are placed in the same
cabinet.
DANGER
2. Safety Precautions
²Wiring must be performed by authorized and qualified
personnel. Risk of danger;
²Circuit-breaker should be installed between VFD and
the mains. Risk of fire;
²Make sure the input power supply has been completely
disconnected before wiring. Failure to comply may
result in personnel injury and/or equipment damage;
²Since overall leakage current of this equipment may be
bigger than 3.5mA, for safety's sake, this equipment
and its associated motor must be well grounded so as
to avoid risk of electric shock;

Use Stage Safety Grade Precautions
Wiring
²Never connect the power cables to the output terminals
(U,V,W) of the VFD. Pay attention to the marks of the
wiring terminals and ensure correct wiring. Failure to
comply will result in damage to the VFD;
²Install braking resistors at terminals (P+)and (P- or PB)
only. Failure to comply may result in equipment
damage.
²Since all adjustable frequency VFDs from Gozuk have
been subjected to hi-pot test before delivery, users are
prohibited from implementing such a test on this
equipment. Failure to comply may result in equipment
damage.
²Signal wires should to the best of the possibility be
away from main power lines. If this cannot be ensured,
vertical cross-arrangement shall be implemented,
otherwise interference noise to control signal may
occur.
²If motor cables are longer than 100m, it is recommend-
ed output AC reactor be used. Failure to comply may
result in faults.
CAUTION
DANGER
²VFD shall be power-on only after the front cover is
assembled. Risk of electrical hazard.
DANGER
Before
Power-on
²Verify that the input voltage is identical to the rated
voltage of product, correct wiring of input terminals R,S,
T or L1, L2 and output terminals U, V, and W, wiring of
VFD and its peripheral circuits, and all wires should
be in good connection. Risk of VFD damage.
CAUTION
²Do not open the cover after power. Rick of electrical
hazard;
²Do not touches any input/output terminals of VFD with
bare hands. Rick of electrical hazard.
DANGER
After
Power-on ²If auto tuning is required, be careful of personal injury
when motor is running. Risk of accident;
²Do not change the defaults of parameters. Risk of
devices damage.

Use Stage Safety Grade Precautions
²Non-professionals shall not detect signals during
operation. Risk of personal injury or device damage;
²Do not touch the fan or the discharging resistor to
check the temperature. Failure to comply will result in
personal burnt.
DANGER
During
Operation
²Prevent any foreign items from being left in the devices
during operation. Risk of device damage;
²Do not control start/stop of VFD by ON/OFF of
contactor. Risk of device damage.
CAUTION
²Maintenance and inspection can only be performed by
professionals. Risk of personal injury;
²Maintain and inspect devices after power is off. Risk of
electric hazard;
²Repair or maintain the VFD only ten minutes after the
VFD is powered off. This allows for the residual voltage
in the capacitor to discharge to a safe value. Failure to
comply will result in personal injury;
²All pluggable components can be inserted or pulled out
only when power has been turned off;
²Set and check the parameters again after the VFD is
replaced.

Ø
Ø
Ø
Please mount inside a well-ventilated location. The ambient temperature is
required to be within the range of -10~40℃. If the temperature is higher than 40
℃, the VFD should be de-rated, at the same time the ventilation and heat
dissipation should be enhanced.
Be away from the location full of dust or metal powder, and mount in the
location free of direct sunlight.
Mount in the location free of corrosive gas or combustible gas.
Humidity should be lower than 90% with no dew condensation.
Mount in the location where vibration is less than 5.9m/s2（0.6G）.
Please try to keep the VFD away from EMI source and other electronic devices
which are sensitive to EMI.
3.2 Mounting Space and Direction
Ø
Ø
Ø
Generally in vertical way.
For the requirements on mounting space and distance, refer to Fig.3-1.
When several VFDs are installed in one cabinet, they should be mounted in
parallel with special incoming and out coming ventilation and special fans.
When two VFDs are mounted up and down, an air flow diverting plate should
be fixed as shown in Fig.3-2 to ensure good heat dissipation.

Single phase motor generally means asynchronous single phase motor powered
by single phase AC 220V, there’re two phase winding in motor stator and motor
rotor is common squirrel cage. The distribution of two phase winding and
different power supply will lead to different starting characteristics and operating
characteristics
Usually single phase motor is with single capacitor or double capacitor, photos of
motor are as below:
