4 FLEX I/O Power Supply Modules
ATTENTION: This product is grounded through the DIN rail to chassis ground.
Use zinc plated yellow-chromate steel DIN rail to assure proper grounding. The
use of other DIN rail materials (for example, aluminum or plastic) that can
corrode, oxidize, or are poor conductors, can result in improper or intermittent
grounding. Secure DIN rail to mounting surface approximately every 200 mm
(7.8 in.) and use end-anchors appropriately. Be sure to ground the DIN rail
properly. Refer to Industrial Automation Wiring and Grounding Guidelines,
Rockwell Automation publication 1770-4.1, for more information.
ATTENTION: Do not remove or replace a Terminal Base unit while power is
applied. Interruption of the backplane can result in unintentional operation or
machine motion.
