Main power is applied to the

EPM-4

through a 10-pin polarized connector. Mating connector Berg

69176-010 (Housing) + Berg 47715-000 (Pins). See the table below for connector pinout and
page 20 location information.

Warning!

To prevent severe and possibly irreparable damage to the system, it is critical that
the power connectors be wired correctly. Make sure to use all three +5VDC pins
and all four ground pins to prevent excess voltage drop. Some suppliers include a
pin-1 indicator on the crimp housing that corresponds to pin-10 of the pinout.
