1.1 Important Safety Warnings
WARNING
HIGH VOLTAGE
ISD 410 servomotors operate at a high voltage when
connected to the electrical supply network. A hazardous
voltage is present on the servomotors whenever they are
connected to the mains network via the power supply
module and the connection box. There are no indicators
on the servomotor that indicate the presence of mains
voltage. This indication is provided on the connection box.
Installation, commissioning and maintenance may only be
performed by qualified staff. Incorrect installation, commis-
sioning or maintenance can lead to death or serious injury.
WARNING
UNINTENDED START
A servomotor that is connected to the electrical supply
network 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 device is connected to the electrical supply
network. Take suitable measures to prevent unintended
starts.
WARNING
DISCHARGE TIME
The DC link capacitors of the servomotors 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
maintenance. The DC links of the individual ISD
servomotors are connected in parallel when they are
connected as a group, which increases the discharge time.
Wait for at least the time listed below before carrying out
maintenance work:
Number
1-60 servomotors
Note: High voltage may be present even if the LED on the ISD
connection box is not lit!
