Commission And Running - INVT Goodrive35 Series Operation Manual

Goodrive35 Series Closed-loop Vector Control VFD
 Install away from children and other public places.
 The VFD cannot meet the requirements of low voltage protection in IEC61800-5-1 if the altitude
of installation site is above 2000m.
 Please use the VFD on appropriate condition (See section 4.2.1 "Installation environment" for
detailed information).
 Don't allow screws, cables and other conductive items to fall inside the VFD.
 The leakage current of the VFD may be larger than 3.5 mA during operation. Perform reliable
grounding and ensure that the grounding resistance is lower than 10 Ω. The conductivity of the
PE grounding conductor is the same as that of the phase conductor. For models higher than 30
kW, the cross sectional area of the PE grounding conductor can be slightly less than the
recommended area.
 R, S and T are the input terminals of the power supply, while U, V and W are the motor
terminals. Please connect the input power cables and motor cables with proper techniques;
otherwise the damage to the VFD may occur.

Disconnect all power supplies applied to the VFD before the terminal wiring
and wait for at least the designated time after disconnecting the power
supply.
High voltage is present inside the VFD during running. Do not carry out any
operation except for the keypad setting. It must be noted that the control
terminals of the VFDs of 3PH AC 500V and 3PH AC 660V are ELV (Extra
Low Voltage) circuit, which cannot be connected directly to the accessible
terminals of other devices if no protective isolation measure is taken.
Control terminals of products -5 and -6 are ELV (Extra Low Voltage) circuits.
Without protection insulation, you need to avoid directly connecting control
terminals 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 be used to break the motor suddenly. A mechanical brake
device should be provided.
Besides the above items, check to ensure the following ones before the
installation and maintenance during the running of the permanent
synchronization motor:
1. All input power supply is disconnected (including the main power
supply and the control power supply).
