Professional Installation Caution
Caution: This product requires professional installation by a licensed
electrician.
•
The unit is sealed at the factory and must not be opened in the field. The unit shall be returned to
the factory for repairs.
•
The Ethernet connector is capable of sourcing power to other devices. Some devices may not be
compatible with this feature. In that case, do not connect the wires that supply the power. The
power is 48 volts DC, up to a maximum of 35 watts.
•
The dust caps must be installed on all unused ports. Without the dust caps, the unit does not meet
the IP66 requirements for water and dust protection. Severe damage to the SkyZhone access point
could occur if the caps are not installed.
Grounding and Isolation
Proper grounding of the SkyZhone platform must be completed before you connect power to the
unit.
•
The internal subassemblies signal/Logic ground is internally bonded to the Safety Ground
(chassis).
•
Proper Safety Grounding is required to insure proper operation and protection from lightning
strikes and surges. A copper ground lug is provided on the unit for this purpose. Connect a
length of #10 AWG solid, bare, copper wire to the grounding lug and firmly tighten the
grounding screw (see Figure 20). Connect the other end of the grounding wire to a grounded
surface or another earth ground such as a metal rod.
Operating Temperature, Venting and Circuit Overload Precautions
Observe the maximum recommended operating temperature as indicated:
•
Maximum ambient operating temperature should not exceed 55
•
Minimum ambient operating temperature should not exceed –35
Do not block system air vents; this will deprive the system of the airflow required for proper
cooling. Sufficient clearance must exist on all sides of the rack to permit equipment access.
Connect the system to the power supply circuit as described in this document. Do not overload
the system or power supply circuit. Ensure that proper system grounding is performed and
maintained.
