ROC800-Series Instruction Manual
Revised July-2017 Input/Output Modules 4-25
Note: Pay close attention to the connections; do not reverse the
power wires. Make these connections only after removing
power from the ROC800. Double-check connections for the
proper orientation before applying power. If the connections are
reversed and power is applied, you may damage both the MVS
module and the ROC800-Series processor board.
Caution
You can induce ground loops by tying commons from various modules
together.
