2.7 LOAD CONNECTION
Load connections to the BOP power supply are achieved via the OUTPUT and COMMON termi-
nals located on the front and rear panels.
Use only one of these output ports. Sense connec-
tions must be made from the same location (front or rear panel) as the output and common
power connections.
2.7.1 LOAD CONNECTION, LOCAL SENSING
The basic interconnections between the BOP and the load using local sensing are shown in Fig-
ure 2-5 (using the rear panel) and Figure 2-6 (using the front panel).
The load wire size for the 2-wire connection shown should be rated for the nominal output cur-
rent of the BOP (20A for the BOP 5-20DL) and tied together to keep parasitic inductance low
and to reduce possible “pick-up” from stray magnetic fields. The basic 2-wire connection is use-
ful where the voltage drop in the load wires is small or of minor consequence, as for example,
operation in constant current mode.
