Wiring for two
SC-2030 with
one TM-2030
Each SC-2030 can deliver up to 31 Amps to batteries. If current exceeds 31
amps, this will not damage the SC-2030 but the battery current will then be
limited to less than 31A to protect the charger and the yellow light will flash.
One unit must be distinguished by inserting a “unit 2” identifying jumper on
connector J6 on rear of SC-2030. Temperature sensor should be placed
on unit 1.
