Precautions of operation
Before turning ON power
CAUTION!
•
Choose appropriate power source with correct voltage setting as the input voltage
specification of the inverter. Check line voltage phase to phase and phase to ground
for compliance.
WARNING!
•
Special care must be taken while wiring the power circuit. The L1, L2 (and L3) terminal
must be connected to input power source and must not be connected to T1, T2, or T3
terminal by mistake. This will damage the inverter when the power is turned on.
CAUTION!
•
Do not attempt to transport the inverter by the front cover. Securely hold the inverter by
the chassis to prevent the inverter from falling.
•
Install the inverter onto firm metal base or other nonflammable material. Do not install
the inverter nearby any flammable material to avoid fire.
•
Additional ventilation fan should be installed if several inverters are installed into one
control panel to lower the temperature inside to below 40°C to avoid overheating.
•
Turn off power supply before proceeding removal or installation of operating panel.
Carry out installation procedure according to instructions given to avoid poor-contact
resulting in operating panel malfunction or display malfunction.
•
The inverter can be easily operated over a wide speed range. Please reconfirm the
operating range of motor and machinery with respective manufacturers.
•
Do not examine the signals on the PCB of the inverter when it is under operation.
•
All inverters have been adjusted properly at the factory. If adjustment is required
consult manual and do not exceed normal operating values.
•
Do not disassemble or examine before ensuring that the power is off and the charge
indicator (LED2) has been extinguished.
•
Insure that all fail safe equipment on machine is operating correctly such as: limit
switches, brakes, etc.
