ATTENTION:
Electric Shock can cause injury or death. Remove
all power before working on this product.
For all 1336 REGEN Line Regeneration Packages, a separate 120VAC 
user power supply is required.
Hazards of electrical shock exist if accidental contact is made with parts 
carrying bus voltage. Before proceeding with any installation or 
troubleshooting activity, allow at least one minute after input power has 
been removed for the bus circuit to discharge. Bus voltage should be 
verified by using a voltmeter to measure the voltage between the DC+ 
and DC– Converter Output Terminals. Do not attempt any servicing 
until bus voltage has diminished to zero volts.
