Edwards Signaling eFSA250 - Manual (Page 10)

viii E-FSA64 and E-FSA250 Technical Reference Manual
Users should ensure for their own protection that the electrical ground
connections of the power utility, telephone lines, and internal metallic water pipe
system, if present, are connected together. This precaution may be particularly
important in rural areas.
Note: The Load Number (LN) assigned to each terminal device denotes the
percentage of the total load to be connected to a telephone loop that is used by
the device, to prevent overloading. The termination on a loop may consist of any
combination of devices subject only to the requirements that the sum of the Load
Numbers of all the devices does not exceed 100.
