DESCRIPTION
INPUT CURRENT RESISTANCE INFORMATION
The Input Current (IC) resistance restricts the current maximum advertised by the EPC . The IC values are as described below:
MAX
no resistor (open, no resistor, IC not connected)

Input resistance less than 100-Ω, MIN, will cause the EPC to reduce the advertised current capacity to 7A for five seconds after which
charging and the interlock will be disabled and the EPC will enter into a forced Status A until input current resistance is increased .
3.4 LED DISPLAY & TROUBLESHOOTING
LED DISPLAY
The EPC has a 3-color LED for displaying operating states and fault conditions . The LED can be lit in blue, green, or red . The meaning of
the individual displays is shown in the following tables:
