1.6 Wiring main circuit and notice
■ Main circuit wiring
The non-fusible-breaker (NFB) should be installed between the AC source and
the R/L1-S/L2-T/L3 input terminal of 7200MA inverter. The user can make his own
decision of installing electromagnetic contactor block (MCB) or not. To protect
against the false triggering of leakage-current, the user should install a leakage
current breaker with amperage sensitivity≧200mA and operation time≧0.1 sec.

*1 : It is assumed constant torque load.
*2 : The main circuit has terminals of R/L1, S/L2, T/L3, U/T1, V/T2, W/T3, B1/P,
B2/R, B2,Θ.
*3 : The control wire is the wire led to the pin terminals of control board.
*4 : In Table 3, the specified Part No. of NFB and MC are the item No. of the
products of Taian. The customer can use the same rating of similar products
from other sources. To decrease the noise interference, be sure to add R-C
surge suppressor (R: 10Ω/5W, C: 0.1µF/1000VDC) at the 2 terminals of coils
of electromagnetic contactor.
