further information on other housings, refer to the
ControlWave Micro Process Automation Controller
Instruction Manual (Part D301392X012). Install the
ControlWave Micro in a suitable ATEX- or IECEx-
approved IP54 or better enclosure, using the
following guidelines:
Base housing. Position as desired on the

enclosure mounting plate and locate mounting
holes on the plate using the ControlWave
Micro as a template. See Figure 2 for
dimensions. Drill and tap mounting holes in the
plate. Position the ControlWave Micro over the
tapped locations and attach to the plate with
four screws (not provided). Torque the screws
to approximately 1.1 to 1.4 N-m.

Expansion housing. Position the expansion

housing to the right of the base housing and
locate mounting holes using the expansion
housing as a template (see Figure 3 for
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
JP2, JP3,
housing to a 4-slot or 8-slot base
& JP4
housing, remove the three bus
jumpers
terminators (JP2, JP3, and JP4, shown on
Figure 2) from the 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 Figure 2) that
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
