3310F Series Operation Manual 53
If a reverse polarity situation occurs the load will sink power even if the LOAD button is
OFF. No current will be displayed on the 3310F series load module. Current up to the
load’s maximum current rating will be tolerated in reverse polarity. However there is no
OVP OCP and OPP protection. It is strongly recommended that the load lines be fused if
it is likely that the load could be subject to reverse polarity. These fuses should be fast
acting and rated at the maximum current of the load module +5%.
