― Product manual
▪ The earthing (grounding) screw of the mounting plate (see section 3.2 Device view on page 14) must also be connected to
the mains-side PE connector via a separate earth lead.
▪ The cross-section of each earth lead must not be smaller than the cross-section of the supply leads (L/N or L1-L3).
▪ The inner PE conductor of the motor cable must be connected to the PE connection point of the motor connector [X6].
▪ The signal lines must be as far away from the power cables as possible. They should not be laid in parallel. If intersections
cannot be avoided, they should be installed at right angles if possible.
▪ Unshielded signal and control lines should not be used. If their use is inevitable, they should at least be twisted.
▪ Even shielded cables will inevitably have short unshielded ends (unless shielded connector housings are used).
In general, the following applies:
▪ Connect the inner shields to the associated pins of the connectors.
▪ Connect the overall shield on the motor side to the connector or motor housing over a large contact area.
9.1.4 Operation with long motor cables
INFO
Compliance with the EMC standard EN 61800-3
Compliance with the EMC standard EN 61800-3 is ensured only for a motor cable length of 25 m maximum.
Operation with longer cables is not permissible.
In applications involving long motor cables and/or in the case of unsuitable motor cables with a non-permissible high cable
capacity, the filters, power output stage and sensors may be overloaded.
9.1.5 ESD protection
NOTICE
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:
▪ Ensure proper earthing of all of the system components and wire the servo drive completely prior to switching on the
voltage supply.
▪ The person commissioning the system as well as the service and maintenance personnel must have undergone ESD
training and wear corresponding footwear.
▪ When handling the system, e.g. the USB connector, it is useful to touch the control cabinet housing (should be at PE poten
-
tial) with your hand prior to touching one of the connectors of the servo drive.
