204 YASKAWA ELECTRIC TOEP C710656 10B YASKAWA Power Regenerative Unit - R1000 Instruction Manual
◆ Power Coordinating Reactor/Current Suppression Reactor
To conform to UL508C, connect the power coordinating reactor to the input side of the drive, input fuses, and the current
suppression reactor to the input side of the regenerative unit. Refer to
Standard Configuration Devices on page 192 for
details.
◆
Installing Standard Configuration Devises
NOTICE: If a fuse is open or an Earth Leakage Circuit Breaker (ELCB) is tripped, check the wiring and the selection of the peripheral
devices. Check the wiring and the selection of peripheral devices to identify the cause. Contact Yaskawa before restarting the
regenerative unit or the peripheral devices if the cause cannot be identified.
■ Recommended Standard Configuration Devises
Yaskawa recommends installing standard configuration devises to maintain compliance with UL508C.
Refer to
Standard Configuration Devices on page 192 for details.
■ Low Voltage Wiring for Control Circuit Terminals
Wire low voltage wires with NEC Class 1 circuit conductors. Refer to national state or local codes for wiring. The
external power supply shall be a CSA certified or cUL Listed Class 2 power source only or equivalent.
Table D.5 Control Circuit Terminal Power Supply
■ Regenerative Unit Short-Circuit Rating
This regenerative unit is suitable for use on a circuit capable of delivering not more than 100,000 RMS symmetrical
amperes, 240 Vac for 200 V class regenerative units and 480 Vac for 400 V class regenerative units, when protected by
fuses as specified on the
Table D.6 .
Connect the regenerative unit to an AC drive which has built-in semiconductor short-circuit protection and conforms to
UL short-circuit test.
