KAESER ASK Series User Manual

For electrical connection of the machine, a symmetric three-phase supply is necessary.
In a symmetrical three-phase supply the phase angles and voltages are all the same.
Incoming line within the switching cabinet to be as short as possible.
If external sensors or communications lines are to be connected to the machine, use shielded ca‐
bles and insert the same through EMC connections into the switching cabinet.
This machine may only be supplied from an earthed TN or TT three-phase supply in which
the neutral point is earthed.
The connection to an IT three-phase supply or a three-phase supply with one earthed phase
is not permitted.
Further information The wiring diagram in chapter 13.4 contains further details of the power supply connection.
2.14 Power supply specifications
Supply diameters and fusing (class gG) are selected according to DIN VDE 0100 part 430
(IEC 60364-4-43) and DIN VDE 0298-4:2013-06 if the following conditions are met:
■ multi-core copper conductors at an operating temperature up to 70 °C
■ Cable length <50 m
■ For an ambient temperature of 30 °C
■ Wiring type C, without cable contact
■ Current carrying capacity: Table 3 Column 11
(European Harmonisation Directive HD 60364-5-522011)
■ Bundled cables: Table 21
─ Single layer on wall or floor
─ Spacing ≥ outside diameter
➤ For other application conditions, check and determine the supply diameters according to
DIN VDE 0100 and DIN VDE 0298-4:2013-06 or the local energy provider.
Other conditions would include, for example:
■ Higher ambient temperature
■ Other cable installation method
■ Other bundled cables
■ Cable length >50 m
