3.7.4. HVAC Operation (PM62815INx Only)
The 6000BTU DC powered HVAC compressor has an internal thermostat. The compressor turns on when the air inside the cabinet is at
28°C and runs for at least three minutes, turning off at 26°C. The heating cycle turns on at 5°C and off at 15°C. The CUBE is equipped
with a cutoff switch that shuts off the HVAC compressor when a door is opened to minimize condensation buildup on the coils. See the
label on the HVAC for firmware information. For further information, refer to the HVAC documentation that ships with the CUBE.
-NOTE-
Changing the cooling or heating cycles’ default factory set points can lead to system performance issues, such as equipment failures, increased
power use, unnecessary alarms, noise, condensation build up, compressor or fan failure caused by excessive runtimes and vibration.
Avoid placing items in front of the HVAC’s return and supply vents. Maintain a minimum of 2” clearance to enable proper air flow.
3.7.5. Overheat Thermostat
The CUBE is equipped with an overheat (high temperature) alarm thermostat in the equipment compartment that provides a normally
closed connection. The overheat alarm is factory set at 50°C and opens the connection if this temperature is exceeded.
-NOTE-
Changing the overheat (high-temp) thermostat default factory set points can lead to unnecessary alarms or system performance issues,
such as equipment failures as a result of unreported alarms.
3.7.6. Alarm Block Connections
A pair of 16-position, labeled alarm blocks monitor the power shelf and other components in the equipment compartment. See the electrical
diagram for information about alarm connections. All connections are normally closed and will open upon alarm.
3.7.7. Slack Storage Tray
The slack storage tray is mounted in the rack rail. For convenience,
the tray can be removed from the rack rail prior to coiling slack.
Note: The total storage capacity of the tray is 147 feet of fiber cable
with a 3mm diameter.
1. Create a fiber service loop by pulling the fiber from the
rack rails toward the tray.
2. Coil the fiber slack inside the tray through one of the
openings in the rear of the tray. Wind the fiber around the
bend controls, observing the proper bend radius. Fiber exits
through the second opening on the rear (Figure 12).
3.7.8. Fiber and Copper Entry
The CUBE has knockouts on both sides that accommodate conduit
fittings. See Figure 2 for knockout locations.
Ø1.25” knockouts accommodate Ø1.00” fittings.
Ø1.50” knockouts accommodate Ø1.15” fittings
Ø1.75” knockouts accommodate Ø1.25” fittings.
Ø2.50” knockouts accommodate Ø2.00” fittings.
3.8. Conduit Seals
All conduit openings on the CUBE must be completely sealed with a duct seal compound to prevent
moisture from entering the CUBE. Use a moldable, flame-retardant putty style duct seal material. Do
not use an expanding foam seal. Mold the putty so that the open space around the wire or conduit is
completely sealed, as shown in Figure 13. If the openings must be accessed at any time, remove the
putty and set it aside. When work is complete, re-mold the putty to re-seal the opening.
3.9. Verifying the Installation
Verify that earth ground and all grounding and bonding is complete and functional. After verifying that
all installer connections are secure and complete, apply voltage.
