7-6 BE1-BPR Installation 9272000990 Rev J
Installing Escutcheon Plates
To install the escutcheon plate kit (Basler part number, 9272013100) you must first remove the mounting
flanges by removing the four screws from the relay (two from each side). To allow the escutcheon plate to
slide onto the relay, remove the four screws from the relay (two from each side).
Horizontal Mount
To install the escutcheon plate in the standard location, it is also necessary to remove four screws, two
each from the relay top and bottom. Position the escutcheon plate at the standard location and reinstall
the attaching hardware.
When installing the escutcheon plate at the alternate location (requires less space behind the mounting
panel), position the escutcheon plate in the alternate location and install the four screws that are provided
with the optional escutcheon plate kit. Reinstall four screws. Reinstall the four screws through the
escutcheon plate into the relay at the alternate location.
Vertical mount relays come with a standard adjustable escutcheon/mounting plate. The
escutcheon/mounting plate is pre-installed to the 9.452 inch depth. This can be easily adjusted to the
alternate location by removing ten screws (two from the top, two from the bottom, and three from each
side), sliding the plate to the alternate location, and fastening with the ten screws. Placement of the plate
in the alternate location requires 8.682 inches of space behind the mounting panel.
Vertical Mount
Vertical mount relays are designed to fit into existing panel cutouts for the following case types. No drilling
is necessary.
• Basler M1 cases
• GE M1 cases
• Westinghouse FT31 and FT32 cases
CONNECTIONS
BE1-BPR relay connections are dependent on the application and protective scheme. Incorrect wiring
may result in damage to the unit.
Terminations
Terminal layout and assignments are shown in Figures 7-6 and 7-7. Figure 7-6 illustrates the terminals of
a horizontal-mount unit and Figure 7-7 illustrates the terminals of a vertical-mount unit.
Typical Connections
Typical ac sensing connections are shown in Figure 7-8. Typical dc control connections are shown in
Figure 7-9.
NOTE
Be sure that the BE1-BPR is hard-wired to earth ground with no smaller than 12
AWG copper wire attached to the ground terminal on the rear of the unit case.
When the BE1-BPR is configured in a system with other devices, connect a
separate lead from the ground bus to each device.
