2. Installation
2.2 Connecting the PDU
2.2.6 Connect PDU Input Plugs: (See the
Configuration and Operation section for more
information.) Connect the Primary input plug
preferred source of grounded 120V/230V AC power,
such as a SmartOnline
system must not share a circuit with a heavy
electrical load (such as an air conditioner or
refrigerator). Under normal operating conditions,
the PDU will distribute AC power from the Primary
input source. Connect the Secondary input plug
to an alternative source of grounded 120V/230V AC
power, such as a redundant SmartOnline UPS
System. The UPS system must not share a circuit
with a heavy electrical load (such as an air
conditioner or refrigerator). Do not plug the
Secondary input into the same power source as the
Primary input. The PDU will distribute AC power
from the Secondary input only if the Primary input
becomes unavailable.
Note: Immediately after the PDU is connected to live AC
power, you may notice a series of soft clicking sounds emitted by
electrical relays within the PDU. The relays may also click
occasionally during the operation of the PDU. This is normal.
2.2.7 Selecting Input Voltage Range (optional:
Models PDUMH20HVAT &
PDUMNH20HVATNET only): This model has two
selectable nominal input voltage ranges: 200V-208V
("LO") and 220V-240V ("HI"). Press the switch
next to the display to toggle the nominal voltage
setting to the desired "HI" or "LO" range. This
setting adjusts the voltage ranges for the primary
and secondary inputs. The display will indicate "HI"
or "LO" for five seconds.
2.2.8 Connect Equipment to PDU: Do not
exceed the load rating of the PDU. The total
electrical current used by the PDU will be displayed
on the digital meter in amperes. Each outlet includes
a green LED that illuminates when the outlet is
receiving AC power.
