Getting Started
2.5.3 Power Distribution Module (LV models only)
An optional output Power Distribution Module (PDM) is available to distribute the output power of the UPS to the critical load. The PDM cabinet has one or two panels, each containing up to 42 poles for breaker switches. This arrangement provides flexibility for the needs of your facility. Each panel is controlled by one 225A feeder breaker. The PDM is enclosed in a separate cabinet that matches the UPS. This option requires a 480 to 208V transformer.
2.5.4 Upgrade Capability
The UPS is available in various output power ratings in both 50 and 60 Hz models. If your power requirements increase, you can upgrade the UPS system to provide more output power with minimum impact on your facility.
2.5.5 Remote Monitor Panel
An optional Remote Monitor Panel (RMP) contains backlit status indicators and a local horn, allowing you to monitor the operational status and alarm condition of the UPS from virtually any location within your facility. You can install multiple RMPs at remote locations to increase your monitoring capabilities. This option is described further in Chapter 6,
2.5.6 Relay Interface Module
An optional Relay Interface Module (RIM) uses relay contact closures to indicate the operating status and alarm condition of the UPS system. The module uses a serial interface line and may support up to eight critical loads. This option is described further in Chapter 6,
2.5.7 Input Isolation Transformer
Optional 480/480, 208/480, or 600/480 Vac input isolation transformers provide an isolated input to the rectifier for applications that require a DC link that is not ground referenced or for applications requiring an input of 208 or 600 Vac. The transformers are contained in separate cabinets.
2.5.8 5% Input Filter
An optional 480/480 Vac 5% input filter reduces input harmonic current distortion and minimizes upstream interference that can damage sensitive hardware components. The filter is contained in a separate cabinet.
