IPE300 series engineering VFD Safety precautions
-3-
Note:
1. Select appropriate tools for VFD delivery and installation to ensure the safe and proper running
and avoid physical injury or death. To ensure personal safety, take mechanical protective
measures like wearing safety shoes and working uniforms.
2. Protect the VFD against physical shock or vibration during the delivery and installation.
3. Do not carry the VFD only by its front cover as the cover may fall off.
4. The installation site must be away from children and other public places.
5.
Use the VFD in proper environments. (For details, see “Installation environment”.)
6. Prevent the screws, cables and other conductive parts from falling into the VFD.
7. As leakage current of the VFD during running may exceed 3.5mA, ground properly and ensure
the grounding resistance is less than 10Ω. The conductivity of PE grounding conductor is the
same as that of the phase conductor (The cross-sectional area of the PE grounding conductor for
30kW and higher models can be reduced).
8. R, S and T are the power input terminals, and U, V and W are the output motor terminals.
Connect the input power cables and motor cables properly; otherwise, damage to the VFD may
occur.
1.4.2 Commissioning and running
 Cut off all power supplies connected to the VFD before terminal wiring, and wait
for at least the time designated on the VFD after disconnecting the power
supplies.
 High voltage presents inside the VFD during running. Do not carry out any
operation on the VFD during running except for keypad setup. For products at
3PH AC660V, the control terminals form extra-low voltage circuits. Therefore, you
need to prevent the control terminals from connecting to accessible terminals of
other devices.
 The VFD may start up by itself when power-off restart is enabled (P01.21=1). Do
not get close to the VFD and motor.
 The VFD cannot be used as an "Emergency-stop device".
 The VFD cannot act as an emergency brake for the motor; it is a must to install a
mechanical braking device.
 During driving a permanent magnet SM, besides above-mentioned items, the
following work must be done before installation and maintenance:
a) All input power supplies have been disconnected, including the main power
and control power.
b) The permanent-magnet SM has been stopped, and the voltage on output end
of the VFD is lower than 36V.
c) After the permanent-magnet SM has stopped, wait for at least the time
