8 Connection
The following chapter describes the connection of the drive controller and the available accessories.
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 [}14].
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 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 (protection class I in accordance with DIN EN 61440). This means
operation is permitted only if the grounding conductor is connected according to requirements.
All protective ground connections are identified by "PE" or the international grounding symbol (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.
8.2 Line routing
Observe the valid provisions for your machine or system, e.g. DIN IEC 60364 or DIN EN 50110, during the installation of
electrical equipment.
