2 Safety
Regulations
2.1 Important Instructions and Explanations
The instructions for operation and maintenance as well as the following safety regulations must be complied with to
safeguard the safety of personnel as well as the function of the unit. All personnel in-stalling/dismantling, starting
up, and servicing the unit must be familiar with and observe these safety regulations. Only qualified personnel may
perform the described work with suitable and intact tools, equipment, test equipment and materials.
Important instructions are highlighted by "CAUTION:", "ATTENTION:", "NOTE:" and indented text.
CAUTION:
This symbol identifies all working and operational procedures requiring absolute compliance to avoid
any danger to personnel.
ATTENTION:
This symbol identifies all working and operational procedures requiring absolute compliance to
prevent any damage, irreparable or otherwise, to the rectifier or its components.
NOTE:
This symbol identifies technical requirements and additional information requiring the operator's
attention.
2.2 Safety Notes / Precautions
Operation and maintenance procedures must be performed only by qualified personnel. The following rectifier
operation and maintenance requirements must be observed at all times to assure maximum safety and
performance.
Operate, service, and maintain the units as described in this manual.
Thoroughly understand unit and system operation and functions.
Understand all controls, indicators, and operating limits.
Before operating the rectifier, learn the significance of possible malfunc-tions and be prepared to take appropriate
action if one occurs.
Understand and observe the following safety notices and precautions.
2.3 Electrical Safety Precautions
The rectifier must be considered energized unless all sources of input power and batteries have been removed and
circuits are checked for voltage by an independent voltmeter.
Capacitors can retain voltage for long periods of time. All capacitors should be discharged with an adequate
device by qualified personnel be-fore rectifier maintenance, troubleshooting or repair is performed.
When switches have been opened or fuses removed to de-energize a circuit for maintenance, the switches and
fuses should be tagged out to prevent accidental closure or replacement.
To the fullest extent possible, all rectifier maintenance should be conducted with external power removed.
When it is absolutely necessary to work on energized equipment, the following precautions must be observed:
-
Never ground test equipment to live buses.
-
Insulate all surrounding circuitry not under inspection with sheet
rubber or dry heavy weight paper.
-
Stand only on rubber matting.
-
Use one hand only and wear insulating rubber gloves.
-
Wear safety glasses.
-
Never work alone.
-
Personnel qualified in CPR (cardiopulmonary resuscitation) should be readily available.
