SAFETY NOTES
The 28V DC GPU is a piece of electrical equipment which carries voltages and currents that are
hazardous to personnel. The following advice must therefore be observed at all times:
•
Installation, operation and maintenance of this equipment must be carried out according to the
instructions in this manual.
•
Ensure that the equipment is handled only by well-trained and authorized personnel.
•
Take suitable measures to ensure that only trained operating and maintenance personnel have
access to the interior of the system; the doors should be kept locked and the keys retained by
authorized persons.
•
System installation, service and maintenance must be performed by trained staff.
•
The relevant regulations of the local codes and standards, and other safety instructions should be
observed.
•
All personnel who have to work on the equipment should be familiar with first-aid procedures
relating to electrical accidents.
•
Even when the equipment is switched off, a few internal parts remain “live” while they are
connected to the incoming supply.
•
Work on the equipment must only take place with the unit switched off and isolated. Proper
Lockout / Tagout procedures must followed at all times.
•
Built-in capacitors can remain charged, even when the complete system is “de-energized”. They
should be suitably discharged by trained personnel before contact is made with the connections.
•
Fuses must not be rewired or shorted out and rewired fuses must not be used. When replacing
fuses, only the same or lower current ratings and the same types (slow-blow, quick-acting, very
quick-acting) should be used.
•
The system environment should be kept as clean as possible and metallic or other electrically-
conducting dust particles in particular must be prevented from being sucked in through the air
inlet.
The warning and hazard notices inside the equipment must be observed.
Explanation of the warning symbols used in these operating instructions are as follows:
WARNING
Appears alongside all instructions which must be followed exactly in order to
eliminate personal injury and corruption/destruction of data
IMPORTANT
Appears alongside all instructions which must be followed in order to eliminate
damage to equipment and/or malfunctions
NOTE
Indicates important information or advice, which must be followed during
