Electrical installation
Mains connection conditions
To ensure undisturbed operation on the supply system with a Power Supply Unit, a
minimum requirement for the short-circuit power at the mains connection applies. The
transition at the mains filter is defined as the mains connection.
The requirement must be met in order to avoid impairment at the Power Supply Unit
and interference with other devices connected in parallel to this mains connection, and
to enable a reliable operating state.
The term “short-circuit power” is a theoretical value of an apparent power occurring in a
current network when a short-circuit is caused at a transfer point.

1) Rsc is defined as the short-circuit ratio of the short-circuit power (Sk) at the mains connection to the rated power (Sn) of
the Power Supply Unit (Rsc = Sk/Sn).
Table 3.5 Mains connection conditions
Procedure:
Define the cable cross-section depending on the maximum current and ambient temperature.
Cable cross-section according to local regulations and conditions.
Use shielded cables, as shown in Figure 3.15.
Wire the Power Supply Unit with the mains supply as shown in Figure 3.15.
Do not switch on the power!
For more information on connection of the terminal X21 precharge see section 3.6.2, p. 37.
For more information on connection of the components see section 3.15, p. 48 ff.
Technical data of components see section A.7, p. 72 ff.
ATTENTION!
If local regulations require the installation of a residual current operated
protective device, the following applies: In case of a fault the Power Supply
Unit is able to generate DC fault currents without zero crossing. The Power
Supply Unit therefore must only be operated with RCDs
1) of type B for AC
fault currents, pulsating and smooth DC fault currents which are suitable for
servo drive operation - see IEC 60755. RCMs
2)
can additionally be used for
monitoring purposes.
