Application Considerations
Installation Guidelines
Turck’s Powerfast products are easy to install by following a few simple guidelines:
• It is important to know the electrical requirements of the application and
to select a cordset that has the proper amperage and voltage ratings for
the application.
• Cables must be supported to prevent movement on the equipment. Per
NFPA 79, the cable must be supported every 12 inches in a non-vertical
run, every 36 inches in a vertical run and every 18 inches when
suspended in air. The cable should also be supported at any connection
points or terminations.
Note: Consult NFPA 79 (Electrical Standard for Industrial Machinery) for required over current protection of conductors and other selection and installation guidelines
for industrial machine applications.
• The cordsets are not intended for disconnection under load. Turck
oers Powerlok ttings that prevent the possibility of disconnection
These ttings are not required for use, but can be used as a
precautionary measure.
• Power should never be supplied from the male connector. The source of
power should always be supplied from the female connector.
• Use Turck closure caps to protect connectors from damage or dirt
when not connected.
Cable Options
Turck oers multiple cable options for the Powerfast products. The
majority of Turck’s Powerfast products use cables that carry a tray
rated, exposed run (TC-ER) approval. Select Turck Powerfast
products may carry an additional STOOW cable approval, although
versions that carry the STOOW and TC-ER approval are also available
as TC-ER only.
Both the STOOW/TC-ER cable and the TC-ER only cable version are
premium cable oerings. However, the TC-ER only version has a
slightly reduced cable outer diameter. This feature oers more
exibility and is a more cost eective solution. This cable option
can be designated by adding a “/S4000” to the end of the part
description where applicable.
