Compaq R6000 - Manual (Page 23)

Introduction 1-13
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.”
