Extended Runtime Modules (ERMs)

The Compaq R6000 UPS also supports Extended Runtime Modules. The UPS rear panel includes a power receptacle where the modules attach. Each ERM consists of dual battery packs in a 3U chassis.

At the recommended 80% load, one ERM will extend the available UPS runtime up to 18 minutes. Two ERMs can be serially connected to each UPS, increasing the total available runtime to up to 30 minutes.

NOTE: These figures were derived using the Compaq recommended 80% load.

Power Distribution Units (PDUs)

You can extend the capabilities of the Compaq R6000 UPS by attaching a Compaq Power Distribution Unit (PDU) to the high current receptacle associated with load segments 1, 2, or 3. This provides 12 additional receptacles to load segments 1, 2 or 3.

The Compaq High to Low Voltage Transformer (250VA), another Compaq Power Distribution Unit, may be connected to the Compaq R6000 UPS to supply two low-voltage outlets at 250 VA. See the documentation included with each unit for Installation and Operation instructions.

You can connect your devices to the PDU using IEC-320 jumper cords (Part No. 295633-B21). To order more IEC cords, see the section in this chapter entitled, “Configuring Load Segments.”
