Rating Units
For DWS 450 VSD+ < 10 mA
†Typical earth leakage values were measured at steady-state conditions.
Note that higher leakage currents may occur:
i) under transient conditions such as power on or pump acceleration
ii) with the abnormal supply configurations such as a missing or earthed phase or
unbalanced supply voltages.
Contact us for more information about the configuration requirements for earth
leakage reduction.
Recommended fuse type:
Fuse Class aR (IEC 60269), UL class T.
3.6.1. Electrical connections
WARNING: NETWORK CONNECTIONS
Risk of injury. Take special safety precautions when you use the machines
controlled by a frequency converter. The safety precautions depend on the type
of network used (TN, TT, IT system). Contact us for more information.
Most pumps are designed for use in TT/TN networks and are intended for an
industrial environment where the electrical supply is separated from the
residential/commercial supply network.
To use the pump in light industrial, commercial or residential environments with a
shared supply network, or in an IT network, extra precautions are necessary.
Contact us for information.
