Main power is applied to the EPM-5 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 16 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 both +5VDC pins and
all ground pins to prevent excess voltage drop. Some manufacturers include a pin-1
indicator on the crimp housing that corresponds to pin-10 of the pinout shown in
Figure 12.
