8 Connection
The following chapter describes the connection of the drive controller and the available
accessories.
The terminal specifications can be taken from the manual on the SD6 drive controller; see the
chapter Detailed information [}161].
8.1 Safety instructions for connection
Connection work is permitted only when no voltage is present. Observe the 5 safety rules; see
the chapter Working on the machine [}15].
If you couple the drive controller in the DC link, ensure that all Quick DC-Link modules are built
over with a drive controller.
The device housing must be closed before you turn on the supply voltage.
When the power supply voltage is turned on, hazardous voltages may be present on the
connection terminals and the cables connected to them.
The device is not reliably de-energized simply because the voltage supply is switched off and all
displays are blank!
Information
Note that the you can only determine that voltage is no longer present once the discharge time
has elapsed. The discharge time depends on the self-discharge of the drive controller. You can
find the discharge time in the general technical data of the drive controller.
Opening the housing, plugging in or unplugging connection terminals, connecting or removing
connecting wiring, and installing or removing accessories are prohibited while the voltage
supply is switched on.
Protect the devices against falling parts (bits or strands of wire, pieces of metal, etc.) during
installation or other work in the control cabinet. Parts with conductive properties may result in a
short circuit inside the devices and device failure as a result.
Use only copper conductors. For the corresponding conductor cross-sections, consult the
standards DIN VDE 0298-4 or DIN EN 60204-1 (Annexes D, G) as well as the relevant terminal
specifications in this documentation.
The protection class of the devices is protective grounding. This means operation is permitted
only if the protective grounding conductor is connected according to requirements.
All protective ground connections are identified by "PE" or the international symbol for
grounding (IEC 60417, symbol 5019).
The products are not designed for use in a public low-voltage network that supplies residential
areas. Radio-frequency interference can be expected if the products are used in this type of
network.
