Customer Power Connections
AC line input power and output motor connections are made by using
customer-supplied barrel lugs that are either crimp or mechanical type. Barrel
lugs that are used to make the power cable connections to bus bars must have
the dimensions in the following graphic.
Figure 13 - UL-listed Barrel Lug Dimensions
Use the vendor-recommended tooling to fasten crimp type terminals to
cabling. Torque mechanical type terminals according to vendor instructions.
L-Bracket Connections
Power cable connections in entry and exit wire bay are made using L-brackets.
The M10 hardware that is required to fasten the L-brackets to the extruded bus
bar is provided. Wires with appropriate barrel lugs can be bolted to both sides
of the L-brackets if necessary. Up to four conductors can be attached to each L-
bracket. Attach the conductors to the L-brackets using M12 or 0.5 in. diameter
bolts, nuts, and washers. Belleville spring washers, or equivalent, are
recommended. Keep the L-bracket connections at least 51 mm (2 in.) away
from the ends of the extruded bus bar.
