Remove Power from the
Device
• Remove and lock-out all incoming power to the device.
ATTENTION:
Remove power before making or breaking cable connections.
When you remove or insert a cable connector with power applied, an
electrical arc can occur. An electrical arc can cause personal injury or
equipment damage by:
• sending an erroneous signal to your systems field devices, causing
unintended machine motion
• causing an explosion in a hazardous environment
Electrical arcing causes excessive wear to contacts on both the device and its
mating connector. Worn contacts can create electrical resistance.
