The enclosed

ePC-Plus units are powered from 100-240 VAC, 50/60 Hz only. Because these are

stand alone Type 1 devices and do not require an additional NEMA type enclosure, a different type power
connection is required. These units use a more standard IEC type power cord like found on most
computers. There is a retention clip that can be utilized to help retain the cord from falling out. A US
three prong cord is supplied. If another country connection method is required then an appropriate UL
recognized power cord can be chosen locally (not supplied by Nematron). Optionally available is an IEC
type connector that can be directly wired to for field wiring. This can be ordered separately from
Nematron and is part number PWR-AC-EN

The ePC-Plus units include a retention mechanism for securing USB connections. USB

connections are not secure and can easily fall out. The use of this mechanism is suggested for all
applications and is required for any hazardous locations installations. Simply remove the bracket insert
your USB cables through the bracket. Connect your USB cables to the unit and move the bracket into
position. Snugly push the bracket toward the USB connector and secure with the screw provided.

On the ePC panel mount, Rack Mount, and Enclosed units the USB bracket is a simple L shaped

bracket with cutouts to retain up to four USB cables and a mounting screw. On the nPC200 the bracket is
two pieces; one (flat piece) is secured to the bottom of the unit using two #4-40 screws and then the other
functions the same as the ePC-Series USB retention bracket.
