Table 7- 25
Cable type: 600 V, UL style 3271, operating temperature 125° C
Risk of fire due to ground fault / short-circuit
Inadequate installation of the cables to the Motor Module DC link can result in a ground
fault/short-circuit and place persons at risk as a result of the associated smoke and fire.
• Comply with local installation regulations that enable this fault to be ruled out.
• Protect the cables from mechanical damage.
• In addition, apply one of the following measures:
Note
Maximum cable lengths
The connections should be kept as short as possible.
The maximum cable length between Power Modules or Motor Modules 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.
Damage to the dv/dt filter compact through mechanical load on the connections
The connections at the dv/dt filter compact are not designed for direct mechanical
connection to the motor cables.
• Take measures on the installation to ensure that the connections cannot be deformed
