Note: Cable must be suitable for a permanent Tª >75ºC. Use 600V cables for up to 500Vac rated
voltage. For 690Vac phase to phase rated equipment use 1kV cables. However, this is a
recommendation; ensure follow local regulation.
6.4. Ground connection
Before connecting the power conductors, be sure that the chassis of the filter, drive and the adjoining
cabinets are connected to ground through the dedicated (PE) terminals. They are situated at both sides
of the bottom metallic walls of the cabinets and they are labelled with the appropriate ground connection.
Check section
“6.9 and 6.10”.
Motor
‟s chassis grounding must be connected to the drive. In other words, connect the motor‟s ground
conductor
to the PE output terminal of the drive and not to the installation‟s ground. We recommend that
the cross section of the
motor‟s ground conductor (PE) should have at least the cross section of the
active conductor (U, V, W). Should be installed following the recommendations indicated in
section “6.3
Power Connection and wiring”.
When connecting the earth, ensure that all connected terminal lugs are securely tight and protected from
mechanical forces. The tightening torque in case of M10 PE terminals is 40Nm.
CAUTION
For safety reasons it is determinant to measure the grounding resistance of the plant itself.
This
must be established before the first start up of the plant and with the drive disconnected.
It is responsibility of the installer to provide the adequate number, type and cross section
grounding conductor
alongside with the characteristics of the drive used and of the Plant in order to
minimize the grounding resistance, that comply with the local and national regulation.
