Terminals and Connectors
Connections to the BE1-11g are dependent on the application and logic scheme selected by the user. As
a result, some BE1-11g inputs and outputs may not be used for a given application. Before energizing a
BE1-11g, make sure the connections match the options associated with the model and style number
found on the BE1-11g nameplate. Refer to the style chart in the Introduction chapter for available options.
Be sure to use the correct input power for the specified power supply. Incorrect wiring may result in
damage to the BE1-11g.
Connections to the BE1-11g voltage inputs, contact inputs, power
supply inputs, and contact outputs should be made with a minimum
wire size of 14 AWG (2.08 mm
2
).
Connections to the BE1-11g current inputs and ground terminal should
be made with a minimum wire size of 12 AWG (3.31 mm
2
).
When the BE1-11g is configured in a system with other protective
devices, a separate ground bus lead is recommended for each BE1-
11g.
BE1-11g protection systems are supplied in either an S1 size case (J option) or an H1 size case (H or P
option).
J Type Case
Figure 199 shows the rear-panel connections with an RJ45 Ethernet connector. Figure 200 shows the
rear-panel connections with a fiber optic Ethernet connector.
