Efficiency Optimizer Function (HE Mode/High Efficiency Mode)
The Efficiency Optimizer Function is a feature for the UPS adding cost effectiveness,
minimizing power loss and reducing power consumption. Alternating between bypass and
on-line modes is achieved automatically and in accordance with the conditions of the utility
power. On-line mode may be used during times of intermittent power supply, and bypass
mode when power flows smoothly in order to obtain greatest efficiency. Irregularities can
be detected in less than a second, and on-line mode reactivated immediately. Switching
back to online mode occurs when input voltage is outside ±10% or nominal (±15%
selectable), when input frequency is outside of ±3Hz or when no input line is available.
Although high efficiency is standard, the default operation is in on-line mode. Bypass can
be activated in the LCD panel though on-line can be run permanently if preferred.
Free Run Mode
The UPS operates in free run mode when input frequency is outside of the selected input
frequency range. Free run mode is when output frequency does not match input
frequency. When starting the UPS, the frequency regulation detected is 50 or 60 Hz
±0.25Hz. Please refer to section 13 if you want bypass available while running in free run
mode.
Diagnostic tests
When you start the UPS, a diagnostic test is automatically executed that checks
electronics, battery, and reports any problems on the LCD display.
An advanced battery management system always monitors the conditions of the batteries
sends any fore warnings if replacement is needed. Otherwise every 30 days of normal
mode operation, a battery discharge test is performed and any problems reported on the
LCD display.
Except during the first 24 hours after startup while the UPS is in charging mode (please
see section 13), diagnostic tests can be performed manually from the front panel at any
time.

SYSTEM CONFIGURATION

The UPS device and the internal backup battery make up the system. Depending on the
site and load requirements of the installation, certain additional options are available as a
tailored solution.
The following items should be taken into consideration when planning a UPS system:

The total demand of the protected system shall dictate the output power rating (VA).
Allow a margin for future expansion or calculation inaccuracies from measuring
power requirements.

Backup time needed defines the battery size needed. If load is less than the UPS
nominal power rating then actual backup time is longer.

The following options are available:
 External Battery Cabinets
 Connectivity options (dry contact card, network monitoring card)
