13.1.5 ESD protection
Damage to property due to ESD (electrostatic discharge)
At unassigned plug connectors, damage can occur to the device or to other system parts
as a result of ESD (electrostatic discharge).
To prevent this type of damage, comply with the following:
l Ensure proper earthing of all of the system components and wire the servo drive
completely prior to switching on the voltage supply.
l The person commissioning the system as well as the service and maintenance
personnel must have undergone ESD training and wear corresponding footwear.
l When handling the system, e.g. the USB connector, it is useful to touch the
control cabinet housing (should be at PE potential) with your hand prior to
touching one of the connectors of the servo drive.
