6.10.3 Mains power terminals (R/L1, S/L2, T/L3)
 Connect these terminals (R/L1, S/L2, T/L3) via a protective fuse breaker or earth leak-
age breaker to 3-phase mains power (some models to 1-phase mains power) for circuit
protection. It is unnecessary to consider phase-sequence.
 It is recommended to add a magnetic contactor in the power input wiring to cut off pow-
er quickly and reduce malfunction when activating the protection function of b maXX
®
BM1000. Both ends of the magnetic contactor should have an R-C surge absorber.
 Please make sure to fasten the screw of the main circuit terminals to prevent sparks
which is made by the loose screws due to vibration.
 When using a GFCI (Ground Fault Circuit Interrupter), select a current sensor with sen-
sitivity of 200 mA, and not less than 0.1-second detection time to avoid nuisance trip-
ping.
 Do NOT run/stop the b maXX
®
BM1000 by turning the power ON/OFF. Run/stop the
b maXX
®
BM1000 by RUN/STOP command via control terminals or keypad. If you still
need to run/stop the b
maXX
®
BM1000 by turning power ON/OFF, it is recommended
to do so only ONCE per hour.
 Do NOT connect 3-phase models to a 1-phase power source.
6.10.4 Output terminals (U/T1, V/T2, W/T3)
 The factory setting of the operation direction is forward running. The methods to control
the operation direction are: method 1, set by the communication parameters, method
2, control by the optional keypad.
 When the b maXX
®
1000 output terminals U/T1, V/T2, and W/T3 are connected to the
motor terminals U/T1, V/T2, and W/T3, respectively, the motor will rotate counterclock
-
wise (as viewed on the shaft end of the motor) when a forward operation command is
received. To permanently reverse the direction of motor rotation, switch over any of the
two motor leads.
 DO NOT connect phase-compensation capacitors or surge absorbers at the output
terminals of the device.
 With long motor cables, high capacitive switching current peaks can cause over-cur-
rent, high leakage current or lower current readout accuracy. To prevent this, the motor
cable should be less than 20 m for 3.7 kW models and below. And the cable should be
less than 50 m for 5.5 kW models and above. For longer motor cables use an output
choke.
 Use a well-insulated motor, suitable for inverter operation.
NOTE
No T/L3 terminal on 1-phase models
