Basic Line Modules with internal air cooling
4.6.1
The Basic Line Modules generate a non-regulated DC voltage, which matches the rectified
line input voltage, from the 3-phase line voltage and feed this DC voltage into the DC link.
One Basic Line Module can supply one or more Motor Modules with power via the DC link.
To reduce the energy, e.g. for emergency retraction, the 20 kW and 40 kW Basic Line
Modules feature a control for an external braking resistor.
For 100 kW Basic Line Modules, an external braking unit is required for degradation of
energy. Either Braking Modules Booksize Compact (also in a parallel connection) or a
MASTERDRIVES braking unit (see Chapter "Braking units for 100 kW Basic Line Modules
(Page 544)") can be used.
Basic Line Modules are suitable for direct operation on TN, IT and TT systems. The Line
Modules have an integrated overvoltage protection function.
The 100 kW Basic Line Module features basic interference suppression, the 20 kW and
40 kW Basic Line Modules do not.
The ratio between the line short-circuit power (system fault level) and the rated power must
be ≥ 30.
The maximum total cable length is as follows:
● For all Basic Line Modules with upstream Basic Line Filter:
– 350 m shielded for radio interference voltage category C2
– 630 m shielded for radio interference voltage category C3
● For 100 kW Basic Line Modules without upstream Basic Line Filter:
– 350 m for radio interference voltage category C3
● For all Basic Line Modules without maintaining the limit values:
– 630 m shielded
Danger to life if the fundamental safety instructions and remaining risks are not carefully
observed
If the fundamental safety instructions and remaining risks in Chapter 1 (Page 25) are not
observed, accidents involving severe injuries or death may occur.
• Adhere to the fundamental safety instructions.
• When assessing the risk, take into account residual risks.
