CTC modular MAXX box solutions allow for the monitoring of remotely mounted
vibration sensors, which would otherwise be restricted to human access due to
safety considerations.
MMX6000 Series Modular MAXX Box Overview: 3-12 Channel boxes, stainless
steel slope top enclosure
The MMX6000 3-12 channel enclosure is a common cable termination point for
bringing in a variety of sensor applications including single axis, biaxial, triaxial,
and dual output (vib/temp) sensors for routine data collection with portable data
collectors.
The MMX6000 Series offers convenient three position quick connect terminal
blocks for terminating the sensor of your choice.
Setup of DIP Switches
In addition to the most popular application of single axis sensors the MMX-MOD3
modules can be setup to provide grouped signals from a Dual Output sensor,
triaxial or biaxial style sensor that share the “common” conductor. By adjusting
the dip switches, the common connection can be shared between inputs 1 & 2,
2 & 3, for dual outputs and between inputs 1 & 2 for biaxial sensors or 1, 2, & 3
for triaxial sensors. This eliminates the need to insert jumper wires between the
different inputs within the module. The switches are displayed further on in this
manual. Note: All modules are set at “Commons OPEN” at factory.

Note: if you have purchased a modular MAXX box without cable entries provided,
you should add your own entry prior to mounting the modular MAXX box. CTC
does not recommend drilling holes in the top of the enclosure due to access and
moisture concerns.

If you are running conduit to your enclosure, ensure the conduit cable entry
enters from the bottom of the enclosure when mounted.
Note: To ensure moisture will not flow into the enclosure, a hole should be drilled
at the lowest point in the conduit to provide drainage for any moisture.

Ensure the shield ground wire on the MMX6000 Series Modular MAXX box is
grounded to earth ground.
A. Mounting to Earth Ground
When mounting MMX6000 Series Modular MAXX boxes to earth ground (such
as an I-Beam), no additional steps are necessary, as the enclosure is grounded
internally.
Figure 5. Proper Shield Grounding Technique

8
B. Mounting to non-grounded structure
When mounting the enclosure to a non-grounded structure, ensure the shield
ground wire or customer supplied ground wire is tied to a source of earth ground.

Installation of sensors/signal input cable
1. Feed blunt end through the cable entry at the bottom of the enclosure.
Note: it is recommended that cables are marked on both ends.
For cord grip cable entry, take off the cord grip cover with bushing and run cable
into enclosure, hand tighten cord grip cover to base to prevent damage of cord
grip.

1. Strip outer jacket of cable back 1¼ in. and remove all of the shielding.
2. Separate the internal wires from the shield and twist the shield.
3. Strip red and black insulation back ¼ in.

4. Locate the appropriate plug, identified by channel number, remove the plug and
install the wires using a small flathead screwdriver. Push plug back into location.
Orientation is as follows:
a. Red insulated conductor wire is connected to (+).
b. Black insulated conductor wire is connected to (-).
c. Shield drain wire is connected to ground (GND).
d. Depress selected position button to open terminal for respective wire (may
require a mini at head screwdriver).

5. Insert plug into the appropriate PC board connector and double check to ensure
that the cable is going to the correct channel.
6. Mark the Measurement Location Card located on the inside front cover with a
description of each measurement location.
