1.
The AC utility conductors installed in the service entrance box must contain a safety ground conductor. The
Smart Tracker installer should verify that this grounding conductor is in place, having been installed along with
the AC utility input.
2.
A separate enclosure ground wire must be connected between the enclosure ground lug and an earth ground
connection provided by a ground rod installed at the Smart Tracker site. In most cases, one copper or copper-clad
steel ground rod of 2.5 meter (8 feet) length driven into the earth will be sufficient to provide the ground
connection required. In some instances, a more elaborate grounding method (such as a ring ground) may be
required; however, this may be dictated by state or local codes and depends on conductivity of the soil within the
installation area.
3.
The dead metal of the service entrance box must be bonded to the metal enclosure that houses the Smart Tracker.
Additionally, the ground bar within the service entrance box should be bonded to the metal enclosures; however,
this requirement may be subject to local codes and practices.
4.
The grounding wire connected between the Smart Tracker enclosure and the earth ground rod should be no
smaller in area than 13 mm² (6 AWG) copper. Both ends of the ground wire should be sealed with an appropriate
anti-oxidation compound.
5.
An optional ground bonding wire of the same size as specified in Step 4 above may be connected between the
optional ground lug at the left side of the Smart Tracker chassis and earth ground where such connection enters
the external system enclosure. Refer to the

Placement in the Enclosure
:
This Smart Tracker has been designed primarily for use within a cabinet or enclosure offering protection from outdoor
weather, entry of excessive dust, dirt or moisture, and from unauthorized contact by untrained personnel. If used in a
controlled environment, the Smart Tracker may be located within an indoor equipment cabinet or may be mounted to
a rack or placed on a shelf. If necessary, adjust the rack mount brackets on each side of the unit to recess outlets
further into the rack to avoid obstruction with enclosure doors.
Clearance of at least 1RU or 1.75 inches must be maintained around all surfaces of this Smart Tracker for
unobstructed airflow. Temperature of the air entering the Smart Tracker should not exceed 74°C (165° F). System de-
rating will occur at 55°C. See Specifications.
Surge Protection
:
Use of an external surge protection device is encouraged. The Smart Tracker does not provide surge protection to any
of the eight outlets available on the front panel in the event of AC utility input voltage spikes.
Wiring
:
Install the Smart Tracker according to the following procedure. Refer to Fig. 3-1 for control and connector positions.
1.
Operate the AC circuit breaker in the service entrance box to the OFF (O) position. Ensure that the branch circuit
breaker chosen to protect the AC receptacle for the Smart Tracker is operated to the OFF position, if necessary.
2.
Operate the Input circuit breaker on the front panel of the Smart Tracker to the OFF (O) position.
3.
Attach the AC power cord to the receptacle on the rear of the Smart Tracker.
4.
Attach the GPS Antenna to the connector on the rear of the unit.
5.
If using the output relays, input contacts, or DC voltage inputs, wire them accordingly.
6.
Connect an Ethernet cable to the Ethernet receptacle on the front panel of the Smart Tracker.
7.
Wiring of the Smart Tracker is now complete.
