1.7 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 MA7200 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 TECO. 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: 10
Ω
/5W, C: 0.1
µ
F/1000VDC) at the 2
terminals of coils of electromagnetic contactor.
