Safety Notes
28
Short Circuit and Electric Shock
To avoid short circuits and electric shock, the power lugs must not be energized before
removing the screws. It is essential to ensure that the power lugs are not energized before
loosening the screws. Be careful with the used tools in order to prevent a short circuit.
PEM Damage
Applying reversal power causes damage to the electrolytic capacitors of the filter. Therefore,
only switch on the breakers if no red light is visible.
Exchanging Fans
Personal Injury
Rotating Fans
Inserting tools or fingers into operational fans may cause injuries.
Fans become exposed when the fan tray is pulled. Keep clear of the fans as long as they are
rotating.
When the fan is removed, extreme care should be taken while handling the fan itself. The
centrifugal forces will make the unit difficult to handle.
Cabling
Personal Injury
The cabling should follow existing cable paths using existing or similar cable fastenings.
Never change the system's cabling as delivered by Artesyn. Check proper function of the
system after cabling extensions. To avoid injuries always ensure that cables are securely
installed so that nobody can trip over them.
Personal Injury through Electric Shock
Touching contacts and cables during system operation can cause injuries through electric
shock.
To avoid electric shock make sure that contacts and cables of the system cannot be touched
while the system is operating. If in doubt concerning cabling, ask your local Artesyn
representative.
