I do not recommend to use one transformer for two units. Each A-100LC3 should have it's own transformer. As the transformer has 2.4A available the max. current would be 600 mA only (= 2400/4). And if the wiring of the second connector is wrong you generate a short circuit and will damage the transformer and possible the supplies and installed modules.
