AC POWER REQUIREMENTS
Standard JBL DrivePack systems are equipped with a DP multi-channel Crown Class-I power amplifier and
loudspeaker specific DSP electronics and require appropriate AC power.
CAUTION: In compliance with safety agency criteria and proper system operation, it is critical
that the system installer observe all electrical safety practices at all times and provide proper earth
grounding for all AC Power connections.
AC POWER CORD KIT
Convenience 10VAC North America NEMA 5-15 Edison type AC plug to PowerCon® connector and
0V Europe CEE 7/7 Schuko type AC plug to PowerCon connector cord sets are provided with this JBL
DrivePack product for light-duty shop testing or system configuration type use.
One spare gray Neutrik (P/N NACFCB) PowerCon connector is included in the AC Power Cord Set for your
convenience to create a pass-through AC power cable. To create a pass-through cable the system installer
may choose to simply cut off the AC plug from one of the provided AC cord sets and replace it with the
provided Gray PowerCon AC Outlet connector. Follow the wiring convention indicated in Table 1.
NOTE: Tighten set screws to .5Nm (1.8lb-ft) torque to prevent opening by hand.

their specific JBL DrivePack system configuration. See Table 1 for custom application wiring and connector
information.
