1. Current limitations of terminals:
TB4 Nonregulated terminals = 2.5 amps
TB4 Nonresettable terminals = 0.3 amps
TB4 Resettable terminals = 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 transformer installed;
6.0 amps with both standard transformer and optional XRM-24 (XRM-24E for 220/240 VAC
applications) transformer installed. Note that total current from TB4 Nonresettable and Resettable
terminals must not exceed 0.600 amps.
