Goodrive350A series high-performance multifunction VFD
Safety precautions
-3-
Protect the VFD against physical shock or vibration during delivery and installation.
Do not carry the VFD by its front cover only as the cover may fall off.
The installation site must be away from children and other public places.
When the installation site altitude exceeds 1000m, derate by 1% for every increase of 100m;
when the installation site altitude exceeds 3000m, consult local INVT dealer or office.
Use the VFD in proper environment. (For details, see "Installation environment".)
Prevent the screws, cables and other conductive parts from falling into the VFD.
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 (with the same cross sectional area).
R, S and T are the power input terminals, and U, V and W are 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
Disconnect all power sources applied to the VFD before terminal wiring, and wait
for at least the time designated on the VFD after disconnecting the power
sources.
High voltage presents inside the VFD during running. Do not carry out any
operation on the VFD during running except for keypad setup. The product
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 P01.21=1. Do not get close to the VFD and
motor.
The VFD cannot be used as "Emergency-stop device".
The VFD cannot act as an emergency brake for the motor; it is a must to install
mechanical brake device.
During driving a permanent magnet SM, besides above-mentioned items, the
following work must be done before installation and maintenance:
a) Disconnect all the input power sources including main power and control
power.
b) Ensure 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 stops, wait for at least the time designated
on the VFD, and ensure the voltage b and - is lower than 36V.
d) During operation, ensure the permanent-magnet SM cannot run again by the
action of external load; it is recommended to install effective external brake
device
or
disconnect
the
direct
electrical
connection
between
permanent-magnet SM and the VFD.
