INTERLOCKS AND I/O INTERLOCKS AND I/O INTERLOCKS AND I/O INTERLOCKS AND I/O
Interlock and I/O connections are made to
connector P3 on the rear of the controller. P3
consists of three, 8-position terminal blocks A, B,
and C (see Figure 3). To wire to these terminal
blocks, perform the following (see Figure 4):
1. Loosen the two (2) screws of P3's connector
housing and remove P3 from the controller.
2. Loosen the four (4) screws holding the terminal
block assembly to the inside of the connector
housing and remove the terminal block assembly
from the housing.
3. Feed the I/O Interlock cable(s) through the
cable grommet attached to the connector housing
and pull out the other side. It may be necessary to
remove the cable grommet to fit the cable(s)
through. If so, slide the grommet connections onto
the cable(s) in the order shown in Figure 4 before
pulling the cable through the connector housing.
For maximum noise immunity, all wiring
>
should be run in cables having a foil shield
with an overall braided shield. The foil
shield provides 100% shielding, while the
braid provides a means of making proper
360° shield terminations at the cable ends.
4. Strip the jacket off the cable(s) 3" from the end
and remove the braid 1.5" from the end (see Figure
5).
5. Strip the individual cable wires, install appropriate
wire ferrules, and connect to the terminal blocks
according to Table 1.

If multiple I/O / Interlock cables are used,
>
connect the exposed 1.5" cable braids
together using copper tape.
6. Rotate the connector housing to achieve desired
routing of the cable bundle (right or left), then
reinstall the terminal block assembly into the
connector housing.
7. Tighten the connector grommet ensuring the
grommet spring makes 360° contact with the
exposed cable braid/copper tape for maximum
noise immunity.
For maximum noise immunity, the shields of the
I/O and interlock cables should also be connected
to earth ground at the end opposite to the MicroPak
controller connections.
If it is necessary or desired to run the interlock and
I/O cable(s) through conduit, an adapter can be
readily purchased that converts the PG21 male
threads of the P3 connector housing to 3/4" NPT
male threads. This adapter is available through
McMaster-Carr as their Part Number 7842K7.
