Goodrive300-19 series open loop vector inverter special for hosit Safety precautions
-7-
Do not carry the inverter by its cover. The cover may fall off.
Install away from children and other public places.
The inverter cannot meet the requirements of medium and low voltage protection in
IEC61800-5-1 if the sea level of installation site is above 2000m.
Please use the inverter on appropriate condition (See chapter Installation environment).
Do not allow screws, cables or other conductive items to fall inside the inverter.
The leakage current of the inverter may be above 3.5mA during operation. Ground with proper
techniques and ensure the grounding resistor 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 input terminals of the power supply, while U, V and W are the output
terminals of the motor. Please connect the input power cables and motor cables with proper
techniques; otherwise the damage to the inverter may occur.
1.4.2 Commissioning and running
Disconnect all power supplies applied to the inverter before the terminal
wiring and wait for at least the designated time on the inverter after
disconnecting the power supply.
High voltage is present inside the inverter during running. Do not carry out
any operation except for the keypad setting.
The inverter may start up by itself when P01.21=1. Do not get close to the
inverter and motor.
The inverter can not be used as “Emergency-stop device”.
The inverter can not be used to break the motor suddenly. A mechanical
braking device should be provided.
Note:
Do not switch on or off the input power supply of the inverter frequently.
For inverters that have been stored for a long time, check and fix the capacitance and try to run
it again before utilization (see Maintenance and hardware fault diagnosis).
Cover the front board before running, otherwise electric shock may occur.
1.4.3 Maintenance and replacement of components
Only qualified electricians are allowed to perform the maintenance,
inspection, and components replacement of the inverter.
Disconnect all power supplies to the inverter before the terminal wiring. Wait
for at least the time designated on the inverter after disconnection.
Take measures to avoid screws, cables or other conductive items to fall into
