■
Installation
• Mount the product vertically on a wall or on a DIN Track. Leave the prescribed space between
this product and the control panel surface and other devices.
■
Main Circuit Power Supply
• Use a three-phase, 200 to 230 V, 50/60 Hz power supply.
■
Operation after Power Interruptions
• If continuing operation is selected for the momentary power interruption restart selection pa-
rameter (P09), the system may unexpectedly start operation after a momentary power inter-
ruption is reset. Exercise suitable caution.
■
Operation Command Selection
• If the operation command selection parameter (P10) is set to “PLC” to enable using the control
circuit terminal inputs (STF and STR), the motor may start operation when the power supply
is turned ON or an alarm is reset if the control circuit terminals are left ON. Exercise suitable
caution. Also, if signals are checked during operation and a voltage is incorrectly applied to the
control circuit terminals, the motor may start moving unexpectedly. Always check safety before
performing signal checks.
■
Motor Overheating Protection (Electronic Thermal)
• The Inverter uses an electronic thermal to protect the motor from overheating. Set the rated
current of the motor in the rated motor current parameter (P01). If more than one motor is op-
erated with one Inverter, set the rated motor current parameter (P01) to 0.0 to disable motor
overload detection, and install a thermal relay between the Inverter and each motor. Set the
thermal relay to the nameplate current at 50 Hz and to 1.1 times the nameplate current at 60
Hz.
■
EEPROM Life
• The EEPROM has a limited life. Use RAM mode when using communications or other meth-
ods to frequently write data.
■
Disposing of the Inverter
• Observe all applicable legal requirements when disposing of the Inverter.
