Mounting the Assembled Adapters on the I/O Base
Overview This section gives guidelines, safety precautions and a procedure for mounting the
assembled Processor and Option Adapter on an I/O base.
Guidelines The assembled adapters connect with the I/O base at these seven points:
l Two plastic snaps on the front of the Option Adapter fit into two slots on the
front of the I/O base
l
The plastic snap extensions on the two sides of the Option Adapter fit into the
two slots on the sides of the I/O base
l The 12-pin connectors on the center of the back walls of the two units mate
together
l
The plastic stirrup on the back of the Option Adapter clips onto the bottom of
the I/O base

CAUTION
ELECTRICAL CIRCUITRY MAY BE EXPOSED
Electrical circuitry on the I/O base may be exposed when an adapter is not mounted. Be
sure that the I/O base is not under power whenever it does not have a Momentum adapter
mounted on it.
To be sure that power is not present, do not insert the wiring connectors to the I/O base until
after the adapter has been mounted. When more than one connector is on the I/O base,
remove all connectors to prevent the unit from receiving power from an unexpected source.
Failure to observe this precaution can result in injury or equipment damage and will
void the product warranty.
