Installation continued

Connecting the PDU continued

2-1Connect Input Plug Adapters (Optional - Model PDUMH20AT Only). The PDU includes two adapters that convert one or both of the L5-20P input plugs to 5-20P input plugs. Connecting the adapters is optional. The PDU will function normally without connecting the adapters.

2-2Connect Secondary Input Cord to PDU. Although the PDU will operate without connecting the Secondary input cord, the Secondary input is required for the PDU's Automatic Transfer Switch function.

2-3Connect PDU Input Plugs. Connect the Primary input plug A to a preferred source of

grounded 120V 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

Bto an alternative source of grounded 120V 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. See the Configuration and Operation section for more information.

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.
