1. Current limitations of terminals:
TB4, Terminals 1 & 2 = 2.5 amps
TB4, Terminals 3 & 4 = 0.3 amps
TB4, Terminals 5 & 6 = 0.3 amps
TB1 and TB2, any one circuit = 2.5 amps
Total current draw from all terminals cannot exceed 3.6 amps with standard XRM-1 transformer installed (4000TAE
transformer for the MS-9200E); 6.0 amps with both standard XRM-1 transformer (4000TAE for the MS-9200E) and
optional XRM-24 transformer (XRM-24E for the MS-9200E) installed. Note that total current from TB4, Terminals 3
& 4 and 5 & 6 must not exceed 0.600 amps.
