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.

DeviceNet Network Installation

The ArmorStart Distributed Motor Controller contains the equivalent of

30 in. (0.76 m) of DeviceNet drop cable's electrical characteristics and

therefore 30 in. of drop cable must be included in the DeviceNet drop cable

budget for each ArmorStart in addition to actual drop cable required for the

installation.

Other DeviceNet System Design Considerations

The separation of the control power and DeviceNet power is recommended

as a good design practice. This minimizes the load on the DeviceNet supply,

and prevents transients which may be present on the control power system

from influencing the communication controls.
