Power Supply

P C
OWER ONNECTORS
Main power is applied to the VL-EPM-24 through a 10-pin polarized connector, with mating
connector Berg 69176-010 (housing) + Berg 47715-000 (pins). See the table below for connector
pinout and page 14 for location information.
Warning!
To prevent severe and possibly irreparable damage to the system, it is critical that
the power connectors are wired correctly. Make sure to use all +5 V
ground pins to prevent excess voltage drop. The power connector is not fuse or
diode protected. Proper polarity must be followed or damage will occur. Some
manufacturers include a pin-1 indicator on the crimp housing that corresponds to
pin-10 of the pinout shown in Figure 11.
Note:
The +3.3 V
that require these voltages.
Figure 11 shows the VersaLogic standard pin numbering for this type of 10-pin power connector
and the corresponding mating connector.
