7.4.2 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 10, “Using Features.”
7.4.3 Options Cabinet
Input Isolation Transformer
An optional 208/208, 480/208, or 600/208 VAC input isolation transformer provides an
isolated input to the UPS rectifier for applications that require a DC link that is not
ground referenced or for applications requiring an input of 480 or 600 VAC. The
transformer is contained in the separate options cabinet.
Bypass Input Isolation Transformer (Dual Input)
An optional 208/208, 480/208, or 600/208 VAC bypass input isolation transformer
provides an isolated input to the UPS bypass for applications that require an isolated
bypass and an independently derived neutral, or for applications requiring an input of
480 or 600 VAC. The transformer is contained in the separate options cabinet.
Output Isolation Transformer
An optional 208/208 or 208/480 VAC output isolation transformer provides an isolated
output to the critical load or for applications that require 480 VAC. The transformer is
contained in a separate options cabinet.
Maintenance Bypass Switch
An internal Maintenance Bypass switch is provided to completely isolate the UPS
during service. The Maintenance Bypass Switch is described in detail in Chapter 9,
“UPS Operating Instructions.”
Power Distribution Module
An optional output Power Distribution Module (PDM) is available to distribute the
output power from the UPS to your critical load. The PDM contains up to 42 circuit
breaker switches (Square-D Type QO or QOB) that can be assigned with flexibility to
meet facility needs. The PDM is enclosed below the hinged top of the Options
Cabinet.
7.4.4 Battery Cabinets
System protection can be enhanced by equipping the UPS system with one to five
battery cabinets containing sealed lead-acid, maintenance-free batteries, in
addition to the internal batteries. The battery cabinets are designed for line up and
match installation and utilize quick disconnect cables for easy installation. The
cabinets use 24 Yuasa Type NPX---100R or NPX---100B batteries.
7.4.5 Parallel Cabinet
The Parallel Cabinet allows the creation of a system that allows two to four UPMs to
operate in parallel capacity or redundancy to provide more capacity than a single
UPM and as backup for each other.
