6.2.3 Maintenance Bypass Switch
An internal Maintenance Bypass Switch is provided to completely isolate the main power processing of the UPS during service. The Maintenance Bypass Switch is described in detail in Chapter 8, “UPS Operating Instructions.”
6.2.4 Cold Start Capability
The 9335 UPS system cannot be powered up without a utility input initially present. Accordingly, it is not able to power a load if the system is not started first on utility power.
6.3UPS Standard Features
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.
Communication option cards are quickly installed in the slot behind the front door panel. X-slot cards are hot pluggable.
