Prepare for Installation Chapter 2
While the drive is intended for installation in factory floor environments of
industrial establishments, the following must be considered when locating the
drive in the application:
• Cables that include control voltage cables, for example, 24V DC, safety,
and communications, are not to be exposed to operator or building
traffic on a continuous basis.
• Location of the drive to minimize exposure to continual traffic is
recommended. If a location to minimize traffic flow is unavoidable,
other barriers to minimize inadvertent exposure to the cabling must be
considered.
• Cables must be routed to minimize inadvertent exposure and/or
damage.
• If conduit or other raceways are not used, we recommend that strain
relief fittings be used when installing the cables for the control and
power wiring through the conduit openings.
• Three-phase power cabling must be kept at least 150 mm (6 in.) away
from EtherNet/IP network cables to avoid noise issues. EtherNet/IP is
an unpowered network. If the device status is important when the power
distribution disconnect is in the OFF position, the CP receptacle
(pin 2 + and pin 3 –) must have an unswitched power source.
Electromagnetic
Compatibility (EMC) The following guidelines are provided for EMC installation compliance.
General Notes
• The motor cable must be kept as short as possible to avoid
electromagnetic emission and capacitive currents.
• Conformity of the drive with CE EMC requirements does not
guarantee that an entire machine installation complies with CE EMC
requirements. Many factors can influence total machine/installation
compliance.
• Drives contain an EMI filter, so it must only be used in installations that
are solidly grounded (bonded) to the building power distribution
ground. Grounding must not rely on flexible cables and must exclude
any form of plug or socket that would permit inadvertent disconnection.
Some local codes can require redundant ground connections. The
integrity of all connections must be periodically checked.
