General Precautions In addition to the precautions listed throughout this manual, the following
statements which are general to the system must be read and understood.
ATTENTION: This drive may contain 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 A-B publication 8000-4.5.2, Guarding Against Electrostatic
Damage or any other applicable ESD Protection Handbook.
ATTENTION: Severe injury or death can result from electrical shock,
burn, or unintended actuation of controlled equipment. Hazardous
voltages may exist in the cabinet even with the circuit breaker in the
off position. Recommended practice is to disconnect and lock out
control equipment from power sources and discharge stored energy in
capacitors, if present. If it is necessary to work in the vicinity of
energized equipment, the safety related work practices of NFPA 70E,
Electrical Safety Requirements for Employee Workplaces, must be
followed. DO NOT work alone on energized equipment!
ATTENTION: Potentially fatal voltages may result from improper
usage of oscilloscope and other test equipment. The oscilloscope
chassis may be at a potentially fatal voltage if not properly grounded.
If an oscilloscope is used to measure high voltage waveforms, use only
a dual channel oscilloscope in the differential mode with X 100
probes. It is recommended that the oscilloscope be used in the A minus
B Quasi-differential mode with the oscilloscope chassis correctly
grounded to an earth ground. Refer to equipment safety instructions
for all test equipment before using with the 1395.
ATTENTION: The CMOS devices used on the control circuit boards
can be destroyed or damaged by static charges. If personnel will be
working near static sensitive devices, they must be appropriately
grounded.
