BE1-46N Installation
NOTE
Be sure the relay case is hard-wired to earth ground with no smaller than 12 AWG copper
wire attached to the ground terminal on the rear of the relay case. When the relay is
configured in a system with other protective devices, it is recommended to use a
separate lead to the ground bus from each relay.

CONNECTIONS
Incorrect wiring may result in damage to the relay. Be sure to check model and style number against the
options listed in the Style Number Identification Chart before connecting and energizing a particular relay.
Except as noted previously, connections should be made with minimum wire size of 14 AWG. Typical dc
control connections are shown in Figure 4-8. Typical ac sensing connections are shown in Figure 4-9.
Typical internal connections are shown in Figure 4-10.
Relays that operate using phase currents to determine the negative sequence component are sensitive to
phase rotation. BE1-46N Negative Sequence Overcurrent Relays are phase rotation sensitive. All
connections shown in this manual assume ABC rotation.
