i.3 Notes for Safe Operation
◆ Receiving
◆ Installation
◆ Wiring
CAUTION
Do not install or operate any power regenerative unit which is damaged or has missing parts.
Failure to observe this caution may result in personal injury or equipment damage (Refer to page
12 )
CAUTION
Lift the cabinet by the base. When moving the unit, never lift by the front cover or the front panel.
Otherwise, the main unit may be dropped causing damage to the unit. (Refer to page
16 )
Mount the power regenerative unit on nonflammable material (i.e. metal).
Failure to observe this caution can result in a fire. (Refer to page
16 )
When mounting units in an enclosure, install a fan or other cooling device to keep the intake air temperature below 45°C.
Overheating may cause a fire or damage to the unit. (Refer to page
16 )
In order to comply to UL regulations, the MOV and current suppression reactor must be installed on the input of the R5 unit.
Refer to the installation diagram. (Refer to page
16 )
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. (Refer to page
24 )
Wiring should be performed only by qualified personnel.
Failure to observe this warning can result in an electric shock or a fire. (Refer to page
24 )
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. (Refer to page 24 )
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. (Refer to page
24 )
Do not perform a withstand voltage test of the power regenerative unit.
It may cause semi–conductor elements to be damaged. (Refer to page
24 )
Connect the power coordinating reactor and the power suppressing reactor as described in this instruction manual.
Improper connection may cause a fire. (Refer to page
24 )
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. (Refer to page
24 )
Tighten terminal screws.
Failure to observe this caution can result in a fire. (Refer to page
