12 ArmorStart EtherNet/IP Distributed Motor Controller Getting Started
Publication 280E-QS001B-EN-P – February 2011
equipment or device as open wiring. The cable shall be secured at intervals not
exceeding 1.8 m (6 ft) and installed in a “good workman-like” manner.
Equipment grounding for the utilization equipment shall be provided by an
equipment grounding conductor within the cable.
*Historically cable meeting these crush and impact requirements were designated
and marked “Open Wiring”. Cable so marked is equivalent to the present Type
TC-ER and can be used.
While the ArmorStart is intended for installation in factory floor environments
of industrial establishments, the following must be taken into consideration when
locating the ArmorStart in the application: Cables, including those for control
voltage including 24V DC and communications, are not to be exposed to an
operator or building traffic on a continuous basis. Location of the ArmorStart to
minimize exposure to continual traffic is recommended. If location to minimize
traffic flow is unavoidable, other barriers to minimize inadvertent exposure to the
cabling should be considered. Routing cables should be done in such a manner to
minimize inadvertent exposure and/or damage.
Additionally, if conduit or other raceways are not used, it is recommended that
strain relief fittings be utilized when installing the cables for the control and
power wiring through the conduit openings.
The working space around the ArmorStart may be minimized as the ArmorStart
does not require examination, adjustment, servicing or maintenance while
energized. In lieu of this service, the ArmorStart is meant to be unplugged and
replaced after proper lockout/tag-out procedures have been employed.
The Hand-Off-Auto (HOA) is a factory installed option that the user may select.
The HOA keypad may require the ArmorStart to be selected and installed as
follows if the application requires frequent use of the hand operated interface by
the equipment operator:
1. They are not less than 0.6 m (2 ft) above the servicing level and are within
easy reach of the normal working position of the operator.
2. The operator is not placed in a hazardous situation when operating them.
3. The possibility of inadvertent operation is minimized.
If the operated interface is used in industrial establishments where the conditions
of maintenance and supervision ensure that only qualified persons operate and
service the ArmorStart's operator interface, and the installation is located so that
inadvertent operation is minimized then other installation locations with
acceptable access can be provided.
