11.1 General
Note: An ECODRIVE03 drive controller must be permanently
connected to the power supply network.

Mains Connections.

Note: Mains lters are available to comply with EMC-limits. For a

Systems", doc.-type DOK-GENERL-EMV********-PRxx.
11.2 The Ground Conditions of the Power Supply Network
Drive controllers of the ECODRIVE03 family can be operated on three-
phase current networks with grounded star point or external conductors
without potential isolation.
Ungrounded networks (IT networks) present the increased danger of
unallowable phase to ground overvoltages occurring. Drive controllers of
the ECODRIVE03 family can be protected against overvoltages
• By connecting them via an isolating transformer (the star point of the
output side and the PE connection of the power supply unit are linked
on a shared ground rail)
- or -
• If the facility is protected via an overvoltage suppressor.
Connecting ECODRIVE03 drive controllers via an isolating tr
ansformer
oers the best protection against overvoltage as well as the greatest
operating safety.
The periodic overvoltage of ECODRIVE03 drive controllers between
phase (L1, L2, L3) and ground may not exceed 1000 V (threshold value).
Transient overvoltage (< 50 µs) may, as per EN61800-3/1996, equal a
max value of 1000 V phase to phase and 2000 V phase to ground.
Note: If higher overvoltages occur, then they must be limited with the
use of overvoltage suppressors in the cabinet or building.
Note: Mains voltages exceeding the specied range require the use
of a step-down transformer.
