Selecting Input Voltage Range:
These models have two selectable nominal input voltage ranges: 200V-208V (“LO”) and
220V-240V (“HI”). Press the button 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.
2.2.4
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. (Select models only. See Feature Set Overviews chart above for
model-specific configurations.)
2.3 Networking the PDU (Models with SNMP Card
Installed only):
For network configuration instructions, please refer to the WEBCARDLX Owner’s Manual
included with this product.

Connect PDU Input Plugs:
(See the
Configuration and Operation
section for more information.) Connect the Primary input
plug
A
to a preferred source of grounded 230V AC power, such as a SmartOnline
®
UPS System.
The UPS 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
B
to an alternative source of grounded 230V AC
power, such as a redundant SmartOnline UPS System. 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.
