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 be 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
