Chapter 5 Operation of Inverter
5.1 Trial Operation
5.1.1 Safety Instructionon Trial Operation
HAZARD
Never open the front cover while the inverter is switched ON.
Otherwise, there is the danger of electric shock.
Never touch the inner side of the inverter while it is power ON,
nor put any foreign matter, i.e., rod or other matter inside the
inverter. Otherwise, it may result in serious damage to the
equipment or death to personnel.
CAUTION
Motor insulation should be checked before the inverter is used for the
first time or reused after a long-term idle. Be sure the insulation resistance
measured is no lower than 5M
An inverter stored for a year or longer must be given powerup test before
use, so that the main circuit filtering capacity of the inverter could be
recovered. Do raise the voltage gradually by using a voltage regulator to
some rated value before it is recharged. Generally, the recharging period
lasts 1~2 hours. Otherwise, there is the danger of electric shock or
exposure.
5.1.2 Check before trial operation
The following steps should be inspected and confirmed before the trial operation of the inverter:
Be sure the application ambient and installation for the inverter is in accordance with the
requirements specified in Clause 3.1.
Be sure the main circuit is correctly wired. The input power supply of the inverter must be
connected to the terminal R, S and T. The output terminal U, V and W must be connected to the
motor.
Be sure the ground terminal is reliably and properly grounded.
Be sure all the switches and terminals are in proper state of off or shutdown.
Be sure there is no short cutting or short to ground of all the terminals and electrified parts.
Be sure all the terminals, connectors and screws are tightly fastened.
Be sure the motor has no other loads.
