You insert the PLC-5/VME processor in two adjacent slots in a 6U
(full-height) VMEbus chassis.
ATTENTION: Make sure that your VME system is powered
off. The PLC-5/VME processor is not designed to be inserted
or removed from a live system.
ATTENTION: Avoid touching the circuit board
and connectors.
After sliding the processor into the VME chassis using its cardguides, use
firm pressure on the top and bottom handles of the processor to make its
P1 connector fit firmly into the connector on the backplane. Tighten the
screws in the top and bottom of the front panel to prevent your
PLC-5/VME processor from loosening.

Allen-Bradley makes specific recommendations for properly grounding its
racks so that their operation is as safe and error-free as possible. VME
systems, on the other hand, may have no formal specifications for
grounding the VME chassis frame. Allen-Bradley recommends that you
ground the VME chassis frame and that you connect the logic ground
(common) of the VME power supply to the chassis frame’s earth ground.
