6.3.1Customer Interface

Computer Interface

One serial communications port, using the standard Powerware XCP interface, is provided via a plug-in interface card inserted in the communications slot on the front of the unit. This interface is supplied as standard with each Powerware 9335. You can use this port to link the UPS to the features described in Chapter 10, “Communications” and Chapter 11, “Options.”

6.3.2 Battery Management

A two-stage charging system ensures that the initial recharge is done in an optimal time, with current limited, constant current, DC applied to the batteries. When terminal voltage reaches a certain level, the charger switches to constant voltage.

6.3.3 Installation Features

Power wiring can be routed through the rear and bottom of the UPS cabinet with connections made to easily accessible terminal blocks at the bottom front of the cabinet. External monitoring and communication control wiring must be installed in accordance with approved wiring methods. Communication wiring can be routed through the top of each cabinet.
