10 Connection
The following chapters describe the connection of the supply modules and drive controllers as
well as the available accessories.
10.1 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 [}17].
Make sure that all Quick DC-Link modules are covered, i.e. built over with a PS6 supply module
or SI6 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 and, if
applicable, the fast discharge. You can find the discharge time in the general technical data.
Information
You can check the output voltage at the marked measuring points at the front of the housing of
the PS6 supply module that are used for the DC link connection of the drive controllers.
ATTENTION!
Material damage due to overload!
Insufficient electrical strength of the measuring device can cause damage or failure of the
measuring device.
▪ Make sure that the measuring device has an electrical strength of at least 1000V
DC
.
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.
