D
Never Short or Ground Output Terminals
If the output terminals are touched with bare hands or the output wires come into contact with the Invert-
er casing, an electric shock or grounding will occur. This is extremely hazardous. Also, be careful not to
short the output wires.
D
Do Not Use a Phase Advancing Capacitor or Noise Filter
Never to connect a phase advance capacitor or LC/RC noise filter to the output circuit. Doing so may
result in damage to the Inverter or cause other parts to burn.
D
Do Not Use an Electromagnetic Switch or Magnetic Contactor
Do not connect an electromagnetic switch or magnetic contactor to the output circuit. If a load is con-
nected to the Inverter during running, an inrush current will actuate the overcurrent protective circuit in
the Inverter.
D
Installing a Thermal Relay
This Inverter has an electronic thermal protection function to protect the motor from overheating. If,
however, more than one motor is operated with one Inverter or multi-polar motor is used, always install a
thermal relay (THR) between the Inverter and the motor and set n033 to 0 (no thermal protection).
In this case, program the sequence so that the magnetic contactor on the input side of the main circuit is
turned off by the contact of the thermal relay.
D
Installing a Noise Filter on Output Side
Connect a noise filter to the output side of the Inverter to reduce radio noise and induction noise.

Induction Noise: Electromagnetic induction generates noise on the signal line, causing the controller
to malfunction.
Radio Noise:
Electromagnetic waves from the Inverter and cables cause the broadcasting radio
receiver to make noise.
