CTC termination box solutions allow for the monitoring of remotely mounted
vibration sensors, which would otherwise be restricted to human access due to
safety considerations.
CT142 Series Termination Box Overview: 2 channel boxes, polycarbonate
enclosure
The CT142 Termination Boxes are a common cable termination point for
bringing compatible cables for dual output temperature and vibration sensors
into a termination box for routine data collection with portable data collectors.
CT series enclosures are designed to have field input cabling installed on the
bottom of the cover.
Rated for NEMA 4X (IP66), the CT142 is resistant to hose directed fluid
and corrosion. The box can also withstand harsh environments, including
temperatures ranging from -58 to 180 °F (-50 to 82 °C). A cover featuring four
self-tapping screws allows the box to be sealed from the elements.

If you have purchased a enclosure without cable entries provided, you should add
your own entry prior to mounting the termination box. CTC does not recommend
putting holes in the top of termination boxes as it will cause restricted access to
the wire termination connection points and also allow possible moisture ingress.
Note: To prevent a buildup of condensation inside the enclosure, provide drainage
by drilling a hole in the lowest point of the conduit.

No ground lug is supplied on the CT142 Series. If the customer desires external
grounding, separateinstallationis required toinsure thebox isproperly connected
to earth ground.
A. Mounting to Earth Ground
When mounting CT142 Series termination boxes to earth ground (such as an
I-Beam), mount the shield ground wire using a mounting bolt through one of the
mounting brackets on the enclosure. See Figure 5 below.

B. Mounting to non-grounded structure
When mounting the termination box 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 cut 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
through it then into the 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.
3. Strip red, black, and white insulation back ¼ in.

4. While viewing the rear of the panel, locate the appropriate channel. Using a mini
flathead screwriver, loosen the three screws for the channel and insert the wires
into the termination block. Orientation is as follows:
a. Red insulated conductor wire is connected to (+) Vibration.
b. Black insulated conductor wire is connected to (-).
c. Shield drain wire is connected to ground (GND).
d. White insulated conductor wire is connected to (+) Temperature.
e. Tighten the screw on each wire to hold it in place.
