housing to the right of the base housing and
locate mounting holes using the expansion
housing as a template (see
dimensions).
Note: Remove the paper label over the
connector on the right back edge of the
base housing to firmly attach the
expansion housing to the base housing.

Note: If you are attaching an expansion housing
to a 4-slot or 8-slot base housing, remove
the three bus terminators (JP2, JP3, and
JP4, shown on
backplane of the 4-slot or 8-slot base
housing.
Drill and tap holes in the mounting plate. Position
the base housing over the tapped locations and
attach to the plate with four screws (not
provided). Do not fully tighten. Plug the expansion
housing into the base housing and attach to the
plate with four screws (not provided). Torque the
eight mounting screws to approximately 1.1 to 1.4
N-m.
3. Find a suitable location for the enclosure assembly.
When choosing an installation site, be sure to check
all clearances. Provide adequate clearance for wiring
and service. Seal any holes placed in the enclosure to
maintain the IP54 enclosure rating. Ensure the
mounting of the assembly meets all weight
requirements and the installation conforms to local
building codes.
4. Properly ground the ControlWave Micro.
Properly grounding the Micro helps to reduce the
effects of electrical noise on the unit's operation and
protects against lightning.
Base housings have a ground lug (see
accommodates up to 5.19 mm (4 AWG) wire size. After
you install the base and any expansion housings and
before you install any modules in the base or expansion
housings, you must run a ground wire between the
base housing ground lug and a known good earth
ground. All earth grounds must have an earth-to-
ground rod or grid impedance of 2.0 ohms or less, as
measured with a ground system tester. The grounding
conductor should have a resistance of 1 ohm or less
between the ControlWave Micro's enclosure ground
and the earth ground rod or grid.
Note: After you install the PSSM In the base
housing, run a 1.63 mm (14 AWG) wire from
the TB1-3 power connection (Ground) to the
same known good earth ground.
If the pipeline-to-earth impedance is greater than 2
ohms, electrically isolate the ControlWave Micro and
install a ground rod or grid grounding system.
The recommended cable for I/O signal wiring is an
insulated, shielded, twisted-pair. The twisted pair and
the shielding minimize signal errors caused by EMI
(electromagnetic interference), RFI (radio frequency
interference), and transients.
5. Install and configure the Power Supply/Sequencer
module (PSSM). Refer to the
