Connecting power

The GigaPlus is supplied with a three position locking terminal block for connecting the -
48 VDC power supply. The middle position is Earth Ground and the outer two positions
are -48 VDC. See the Figure below.

Figure 19 Power Connection on Front Panel

Although only one of the -48 VDC connections is required, dual power supplies can be
used to provide redundancy by connection the left position to one supply and the right
position to the other supply.
Internal diodes prevent current from flowing the wrong direction in the case that one of
the power supplies should fail. Under normal operation the current will be divided
between the two supplies.
As mentioned previously, the power supply wires should be twisted to improve the
noise rejection of the system.
The wiring used should be two stranded copper wires of a size no smaller than 18 AWG.
The wires should be twisted together to reduce susceptibility to noise. At least one turn
per inch is recommended. Tighten the two #2 screws to the chassis after installation of
the connector to prevent it from pulling out.
