ATTENTION: This product and its associated equipment
contains ESD (Electrostatic Discharge) sensitive parts and
assemblies. Static control precautions are required when
installing, testing, servicing or repairing this assembly.
Component damage may result if ESD control procedures are
not followed. If you are not familiar with static control
procedures, reference publication 8000-4.5.2 "Guarding Against
Electrostatic Damage" or any other applicable ESD protection
handbook.
ATTENTION: Only personnel familiar with the 1336 REGEN
Line Regen Package and associated equipment should plan or
implement the installation, start-up and subsequent maintenance
of the system. Failure to comply may result in personal injury
and/or equipment damage.
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.
