•
When removing and installing the terminal cover with a screwdriver, be sure not to
scratch your hand as these results in injury.
•
Pressing too hard on the screwdriver may scratch the inverter.
•
Always turn the power off when removing the wiring cover.
•
After wiring is complete, be sure to replace the terminal cover.
•
The main unit must be installed on a base that can bear the unit's weight.
Mandatory
If the unit is installed on a base that cannot withstand that weight, the unit may fall,
action
resulting in injury.
•
If braking is necessary (to hold motor shaft), install a mechanical brake.
The brake on the inverter will not function as a mechanical hold, and if used for that
purpose, injury may result.
■ Wiring
•
Do not connect input power to the output (motor side) terminals (U/T1, V/T2, W/T3).
Connecting input power to the output could destroy the inverter or cause a fire.
•
Do not insert a braking resistor between DC terminals (between PA/+ and PC/- or PO
and PC/-). It could cause a fire.
•
First shut off input power and wait at least 15 minutes before touching terminals and
wires on equipment (MCCB) that is connected to inverter power side.
Prohibited
Touching the terminals and wires before that time could result in electric shock.
•
Do not shut down the external power supply on ahead when VIA or VIB terminals are
used as logic input terminal by external power supply.
It could cause unexpected result as VIA or VIB terminals are ON status.
•
Electrical construction work must be done by a qualified expert.
Connection of input power by someone who does not have that expert knowledge may
result in fire or electric shock.
•
Connect output terminals (motor side) correctly. If the phase sequence is incorrect,
the motor will operate in reverse and that may result in injury.
•
Wiring must be done after installation.
If wiring is done prior to installation, that may result in injury or electric shock.
•
The following steps must be performed before wiring: (1) Turn off all input power. ; (2)
Wait at least 15 minutes and check to make sure that the charge lamp is no longer lit.
; and (3) Use a tester that can measure DC voltage (400VDC or 800VDC or more),
and check to make sure that the voltage to the DC main circuits (across PA/+ - PC/-)
Mandatory
is 45V or less. If these steps are not properly performed, the wiring will cause electric
action
shock.
•
Tighten the screws on the terminal block to specified torque.
If the screws are not tightened to the specified torque, it may lead to fire.
•
Check to make sure that the input power voltage is +10%, -15% of the rated power
voltage (±10% when the load is 100% in continuous operation) written on the name
plate. If the input power voltage is not +10%, -15% of the rated power voltage (±10%
when the load is 100% in continuous operation), this may result in fire.
•
Set a parameter f 109 when VIA or VIB terminals are used as logic input terminal.
If it is not set, it could result in malfunction.
•
Ground must be connected securely.
If the ground is not securely connected, it could lead to electric shock or fire.
Be Grounded
■ Wiring
•
Do not attach devices with built-in capacitors (such as noise filters or surge absorbers)
to the output (motor side) terminals. This could cause a fire.
Prohibited
■ Operations
•
Never touch the internal connector while the upper terminal cover of control panel is
opened. There is a risk of electrical shock because it carries a high voltage.
•
Do not touch inverter terminals when electrical power is going to the inverter even if
the motor is stopped. Touching the inverter terminals while power is connected to it
may result in electric shock.
Prohibited
•
Do not touch switches when the hands are wet and do not try to clean the inverter with
a damp cloth. Such practices may result in electric shock.
