6.4 dv/dt filter compact plus Voltage Peak Limiter
Cable cross-sections
In a dv/dt filter with separate Voltage Peak Limiter (Type 4), the connections between dv/dt
reactor and Voltage Peak Limiter are already installed on the Voltage Peak Limiter.
Table 6- 27
Table 6- 28
Cable type: 600 V, UL style 3271, operating temperature 125 °C
CAUTION
The connection to the DC link of the Power Module or Motor Module must be routed
according to IEC 61800-5-2:2007, Table D.1 in order to rule out short-circuiting or ground
faults.
This can be accomplished, for example, by:
• Eliminating the risk of mechanical damage to the cables
• Using cables with double insulation
• Maintaining adequate clearance, using spacers, for example
• Laying the cables in separate cable ducts or pipes
Note
The connections should be kept as short as possible.
The maximum cable length between Power Modules or Motor Module and dv/dt filter
compact (motor cables and cables to the DC link) is 5 m.
An equivalent cable type must be used when replacing enclosed cables.
The connections at the dv/dt filter compact are not designed for direct mechanical
connection to the motor cables.
The customer is responsible for ensuring that mechanical loading caused by connected
cables cannot bend the terminals.
