W A R N I N G
DISCHARGE TIME
The servo system contains DC-link capacitors that remain charged for some time after the mains supply is switched off at the
Power Supply Module (PSM 510). Failure to wait the specified time after power has been removed before performing service or
repair work could result in death or serious injury.
To avoid electrical shock, fully disconnect the Power Supply Module (PSM 510) from the mains and wait for the capacitors to
fully discharge before carrying out any maintenance or repair work on the servo system or its components.
Minimum waiting time (minutes)
15
D A N G E R
Risque du choc électrique. Une tension dangereuse peut être présentée jusqu’à 15 min après avoir coupé l’alimentation.

UNINTENDED START
The servo system contains servo drives, the PSM 510, and DAM 510 that are connected to the electrical supply network and can
start running at any time. This may be caused by a fieldbus command, a reference signal, or clearing a fault condition. Servo
drives and all connected devices must be in good operating condition. A deficient operating condition may lead to death, serious
injury, damage to equipment, or other material damage when the unit is connected to the electrical supply network.
Take suitable measures to prevent unintended starts.
W A R N I N G
UNINTENDED MOVEMENT
Unintended movement may occur when parameter changes are carried out immediately, which may result in death, serious in-
jury, or damage to equipment.
When changing parameters, take suitable measures to ensure that unintended movement cannot pose any danger.
C A U T I O N
DANGER OF BURNS
The surface of the servo drives can reach high temperatures of over 90°C during operation.
Do not touch the servo drives until they have cooled down.
N O T I C E
RCD COMPATIBILITY
The servo system contains components that can cause a DC current in the protective earthing conductor, which may result in
malfunction in any devices connected to the system.
Where a residual current-operated protective (RCD) or monitoring (RCM) device is used for protection in case of direct or
indirect contact, use a type B RCD or RCM device on the supply side of the system components.
