1.1 Important Safety Warnings
WARNING
HIGH VOLTAGE
The ISD 410 servo system contains components which
operate at a high voltage when connected to the electrical
supply network. A hazardous voltage is present on the
servomotors, the power supply module and the
connection box whenever they are connected to the mains
network. There are no indicators on the servomotor that
indicate the presence of mains voltage. This indication is
provided on the connection box. Installation, commis-
sioning and maintenance may only be performed by
qualified staff. Incorrect installation, commissioning or
maintenance can lead to death or serious injury.
WARNING
UNINTENDED START
The ISD 410 servo system contains servomotors which are
connected to the electrical supply network and can start
running at any time. This may be caused by an external
switch, a CAN bus command, a reference signal, or clearing
a fault condition. Servomotors 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.
WARNING
DISCHARGE TIME
The servomotors, the connection box and the power
supply module contain DC link capacitors, that remain
charged for some time after the mains supply is switched
off at the power supply module.
To avoid electrical shock, fully disconnect the power
supply module from the mains before carrying out any
maintenance on the ISD servo system or its components.
Wait for at least the time listed below before carrying out
maintenance work:
Number
Minimum waiting time (discharge time)
1-60 servomotors
10 minutes
Note: High voltage may still be present even if the LED on the
ISD connection box is not lit!
