FSP Amplifier Short Form Installation Guide Introduction
Wiring
CAUTION
• Do not connect a three-phase power supply to the U, V, or W output terminals.
Failure to observe this caution may result in injury or fire.
• Securely connect the power supply terminal screws and motor output terminal
screws.
Failure to observe this caution may result in fire .
• Do not bundle or run power and signal lines together in the same duct. Keep
power and signal lines separated by at least 30 cm (11.81 in).
Failure to observe this caution may result in fire .
• Use twisted-pair shielded wires or multi-core twisted pair shielded wires for
signal and encoder (PG) feedback lines.
The maximum length is 3 m (118. 11 in) for reference input lines and is 20 m (787.40 in) for PG
feedback lines. If feedback lines are longer than 20 m (787.40 in), use the 50 m (1968.50 in) cable.
• Do not touch the power terminals for 5 minutes after turning power OFF
because high voltage may still remain in the FS P Amplifier.
Make sure the charge indicator is out first before starting an inspection.
• Avoid frequently turning power ON and OFF. Do not turn power ON or OFF
more than once per minute.
Since the FSP Amplifier has a capacitor in the power supply, a high charging current flows for 0.2
seconds when power is turned ON. Frequently turning power ON and OFF causes main power
devices like capacitors and fuses to deteriorate, resulting in unexpected problems.
• Observe the following precautions when wiring main circuit terminal blocks.
Failure to observe this caution may result in injury, fire, or malfunction.
Remove the terminal block from the FSP Amplifier prior to wiring.
Insert only one wire per terminal on the terminal block.
Make sure that the core wire is not electrically shorted to adjacent core wires.
The leakage from the power lines may be extremely large for 400 V FSP Amplifier. Be sure to
secure the wiring of the power lines.
• Do not connect the FSP Amplifier for 100 V and 200 V directly to a voltage of
400 V.
The FSP Amplifier will be destroyed.
• Be sure to wire correctly and securely.
Failure to observe this caution may result in motor overrun, injury, or malfunction.
• Always use the specified power supply voltage.
An incorrect voltage may result in burning.
• Take appropriate measures to ensure that the input power supply is supplied
within the specified voltage fluctuation range. Be particularly careful in places
where the power supply is unstable.
An incorrect power supply may result in damage to the product.
• Install external breakers or other safety devices against short-circuiting in
external wiring.
Failure to observe this caution may result in fire.
