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.
