4-11 Wiring
Parameter F.015 should be set to the sum of the wattage for both
resistors.
Installing Circuit Breaker
To protect the AC input power, install a circuit breaker with
supplemental contact (CB) in the AC input power line. Refer to
Figures 4.1 to 4.3 for the wiring. The rated ampacities of the
circuit breakers are as follows:
For Model 8720MC-RPS027BM unit : 50 Amps
For Model 8720MC-RPS065BM and
8720MC-RPS065BS units
: 100 Amps
The following are the recommended circuit breakers with
supplemental contact.
For Model 8720MC-RPS027BM unit:
Fuji Electric - SA100BA/50WD
BU3ESB-50 W (UL-listed)*
Westinghouse - FDB3050*
or equivalent
For Model 8720MC-RPS065BM and 8720MC-RPS065BS units:
Fuji Electric - SA100BA/100WD
BU3ESB-100 W (UL-listed)*
Westinghouse - FDB3100*
or equivalent
* Because supplemental contact of this circuit breaker does not
conform with load of 5mA, relay with less than 5mA should be
used for connection when a supplemental contact is connected
with sequence input PWR.
Be sure to provide required quantity of circuit breakers with
supplemental contact (CB) for all units connected in parallel (see
Figure 4.2 or 4.3).
Installing Main Magnetic Contactor
The 8720MC-RPS Regenerative Power Supply uses a magnetic
contactor for turning the main power supply ON/OFF. Install and
wire the main magnetic contactors as shown in Figure 4.1 to 4.4.
After the RUN sequence signal entered and the precharge operation
is completed, the main magnetic contactor will be turned ON.
Conversely, when the RUN sequence signal is turned OFF, or when
a fault occurs, the main magnetic contactor will be turned OFF and
the discharge operation will begin.
The following are the recommended main magnetic contactors.
For Model 8720MC-RPS027BM unit:
Allen-Bradley - 100-C23x10 or 100-C30x10 (CE
marked) (where x is voltage suffix
code of operating coil)
Fuji Electric - SC-N1 (UL listed component)
