Main power is applied to the EPM-15 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 Figure 7 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 +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 11.
