Installation/Wiring

General Notes
• Without external mitigation, LPM15 drives are not intended to be used
on a low-voltage public network which supplies residential or office
premises; low frequency and radio frequency interference is expected if
used in such an environment.
• The drive motor cable should be kept as short as possible in order to
minimize capacitive currents which are a source of high frequency
conducted emissions.
• Use of line filters in unearthed supply systems is not recommended.
Requirements for CE Compliance
1. Compliance with all warnings in this manual relating to electrical shock
and thermal considerations in the installation.
2. In general, machines in the industrial environment must meet the high
frequency emission requirements of EN 61000-6-4. Machines in the
residential, commercial, and light industrial environment must meet the
high frequency emission requirements of EN 61000-6-3.
3. Suitable high frequency line filter to mitigate conducted high frequency
emissions.
4. Suitable line inductors for mitigation of harmonic current emissions if
necessary for the application (public low voltage supply system).
5. Suitable enclosure which provides adequate mitigation of high frequency
radiated emissions.
6. Grounding as described in Grounding the Drive on page 1-15.
7. Output power wiring to the motor and all control/signal wiring must use
braided, shielded cable with a shield coverage of 75% or greater, or
metal conduit.
8. The shields of all shielded cables must be terminated with the proper
connectors to chassis/earth.
