Earth Fault detection is set to active on one EPS per battery location. A battery location is any
cabinet connected to the master 4100 communications channel without a TIC. A transponder
cabinet is another battery location. Only ONE earth fault circuit should be active on all power
supplies (EPS, TPS, SPS, RPS) within a battery location. Disable earth fault detection on all
other power supplies at a battery location. Any system that includes one or more EPS MUST
have earth detection from an EPS.
