W ARNING
Only commence wiring after verifying that the power supply is turned OFF.
Failure to observe this warning can result in an electric shock or a fire.
Wiring should be performed only by qualified personnel.
Failure to observe this warning can result in an electric shock or a fire.
Make sure to ground the ground terminal
before connecting the other terminals.
Failure to observe this warning can result in an electric shock or a fire.
Install adequate branch short circuit protection according to applicable codes.
Failure to comply could result in damage to the drive.
The device is suitable for circuits capable of delivering up to 100 kA RMS Symmetrical Amperes, 240 Vac maximum (200 V Class), 480 Vac
maximum (400 V Class) or equivalent to the SCCR rating of the VFD to which it is connected - whichever value is less.
R5 Series of Power Regenerative devices shall be connected to a VFD which incorporates Solid State Short Circuit Protection Circuitry and was
found to comply with the High Fault Current Short Circuit Test.
CAUTION
Verify that the power regenerative unit rated voltage coincides with the AC power supply voltage.
Failure to observe this caution can result in personal injury or a fire.
Do not perform a withstand voltage test of the power regenerative unit.
It may cause semi-conductor elements to be damaged.
Connect the power coordinating reactor and the power suppressing reactor as described in this instruction manual.
Improper connection may cause a fire.
Verify that the rated voltage of the power regenerative unit coincides with the rated voltage of the power regenerative unit to be
connected.
Failure to observe this caution can result in a fire.
Tighten terminal screws.
Failure to observe this caution can result in a fire.
